Project Overview
We have an MVP built with Streamlit that helps users input their macronutrient needs (protein, fats, carbs) and receive AI-generated recipe suggestions using OpenAI’s API. The app is currently deployed on Replit, but it has several limitations that need to be addressed. We are looking for a backend developer to improve and migrate the backend, ensuring it integrates seamlessly with a new React frontend (which I will handle myself). Additionally, the recipe data, which is currently stored in multiple raw files, needs to be moved to a structured database (SQL or Supabase). Project Requirements The backend developer will be responsible for: ✅ Backend Migration (if needed) The current backend is built with Streamlit, but it lacks flexibility and scalability. If necessary, migrate the backend to Flask or Django for a more robust API-based architecture. ✅ API Development & Integration Ensure smooth integration between the backend and the new React frontend. Expose necessary endpoints for frontend interaction (e.g., user authentication, recipe queries, OpenAI interactions). ✅ Database Setup & Migration Move recipe data from raw files to a proper SQL-based database (e.g., PostgreSQL, MySQL, or Supabase). Optimize queries for fast and efficient recipe retrieval based on user inputs. ✅ AI & OpenAI API Handling Ensure OpenAI API is being used efficiently for recipe generation. Implement caching or optimization strategies if necessary (to reduce API costs). ✅ Authentication & Payments (Stripe, Supabase Auth, etc.) Ensure that authentication (if handled by Supabase) remains intact. Ensure Stripe payments (if used) are properly integrated into the backend. ✅ Data Processing & Machine Learning The app uses Pandas, NumPy, SciPy, and Scikit-learn for processing recipes and nutritional calculations. The freelancer must be proficient in these libraries to maintain or improve the current functionality. Ideal Candidate Strong experience in Python backend development (Flask or Django preferred). Experience with API development & database management. Proficiency in Pandas, NumPy, SciPy, and Scikit-learn (a must). Familiarity with Supabase and Stripe (a plus). Ability to optimize performance and scale the backend. Experience working with OpenAI API Good communication skills and ability to work with a frontend developer.

Project Overview
We’re building an AI-powered voice assistant app for Spanish-speaking service businesses (e.g., salons, clinics) to automate phone calls, answer FAQs, and book appointments.

You can see our MVP at https://recepcionistaai.com Key Features • Real-time voice interaction with callers in natural Spanish (multiple dialects) • Integration of LLMs (e.g., GPT-4, Claude) for dynamic conversations • AI-driven appointment scheduling with Google Calendar/Calendly • Admin dashboard for businesses to configure workflows, FAQs, and voice preferences Current Tech Stack (Open to Improvements) • Frontend: React + TypeScript • Backend: Python + FastAPI (RESTful APIs) • Database: PostgreSQL (open to NoSQL alternatives if justified) Open to Suggestions If you propose a better stack (e.g., Next.js for frontend, Go/Rust for backend), explain why it benefits scalability, latency, or cost. Scope of Work 1. AI/ML Development (Priority) • Integrate speech-to-text (STT) and text-to-speech (TTS) systems (e.g., ElevenLabs, OpenAI Whisper) for fluid Spanish conversations. • Fine-tune LLMs (GPT-4, Claude, or Mistral) to handle industry-specific jargon (e.g., medical terms for clinics). • Implement call-handling logic using Twilio/Voximplant APIs. 2.

Description:
We are building a scalable, responsive and secure web application targeting the public sector (local governments) and private providers. This is not a marketplace or a store — it's a SaaS-style tool focused on structured communication and formal procedures between two verified user types. We’re in the MVP phase and need a professional, detail-oriented full-stack developer (or team) to bring this platform to life using Next.js + Django. While we already have the branding, component structure, and functional mockups done, we need someone to take this from prototype to production-ready code with a focus on best practices (modularity, security, performance, and clarity). 🔍 About the platform (overview only): The web app allows two roles: Public Institutions (such as city councils) — who publish structured needs. Verified Providers — who browse, filter, and respond to those needs via a proposal. Each role will have a custom dashboard, forms, notification options, file attachments, and activity logs. The platform must also include a basic admin module to monitor usage and manage plans. We already validated the concept with a pilot involving several municipalities. Now, it’s time to build it right. 🛠️ Tech Requirements Frontend: Next.js (preferred) or modern React Fully responsive (mobile-first approach) Basic theming system (light/dark mode) Backend: Django / Django REST Framework PostgreSQL (structured models for users, roles, opportunities, responses, evaluations, etc.) Role-based permissions logic Other: Email authentication (including institutional domain verification) File upload (PDFs, securely stored) Email notifications Internationalization-ready (Spanish + English to start) Subscription logic (after 6-month free period) Admin panel (users, plans, data access) 📌 Key Features (simplified) Dual registration flow (institution / provider) Structured publication form (title, category, deadline, location map, budget, etc.) Search & filter opportunities (by location, category, deadline) Proposal submission (with PDF upload and basic description) System of proposal review & response status per item Dashboard analytics per role PDF or Excel export of publication data Responsive UI + smooth UX 💼 We provide: Examples from similar platforms Legal and copywriting support 👤 Who you are: You’ve built real-world platforms or SaaS products You write clean, modular, scalable code You care about UX and UI consistency You understand the value of clarity and communication You’re comfortable working with agile structure, async updates You understand basic B2B/B2G logic

TITLE: Build a Dockerized Anomaly Detection Pipeline for User Activity Data (2-Week Project)
PROJECT OVERVIEW: We have an urgent requirement for a production-ready anomaly detection pipeline, to be delivered within 2 weeks. This system will: - Fetch user activity data from multiple REST APIs (up to 10 endpoints). - Store it in a local PostgreSQL database. - Run anomaly detection (ML inference) to flag suspicious behavior. - Broadcast alerts via RabbitMQ. A training mechanism is needed—first to learn user baselines, then to transition to real-time anomaly detection. Additionally, if an anomaly is later labeled as “normal” by an admin (through a separate dashboard built by another team), your system must expose an API so these labels can be saved and used to improve or retrain the model over time. We also require a simple HTML dashboard (in this project scope) to display detection results. (Note: The more advanced “admin labeling” dashboard is handled by another team.) SCOPE & REQUIREMENTS: 1) Data Ingestion & Database - Write a Python script that runs every 5 minutes to query ~10 REST APIs for new user activity data (e.g., application usage, device usage, email activities, file operations, network traffic, etc.). - Maintain a last-fetched timestamp in PostgreSQL to ensure incremental data retrieval. - Store the fetched data in structured tables (PostgreSQL). 2) RabbitMQ for Messaging - After each successful data ingestion, send a timestamp signal to RabbitMQ. - Multiple worker services will pick up this signal to run ML inference. 3) ML Inference & Anomaly Detection - Workers receive RabbitMQ messages, load the latest data (covering multiple activity domains), and run anomaly detection. - Models should consider cross-domain correlations (for instance, unusual network usage paired with abnormal file operations). - Account for user roles (e.g., accountant, developer) to differentiate normal patterns. - Store anomaly flags and scores in PostgreSQL; send an alert (via RabbitMQ or a dedicated channel) if anomalies are detected. 4) Automated Training - Implement an auto-training pipeline that: • Uses an initial period (e.g., historical data or the first chunk of data) to learn each user’s normal behavior. • Switches to real-time inference after that initial training. • Supports re-training as data evolves over time. 5) Feedback Mechanism (API for Admin-Labeled Data) - Provide an API endpoint to capture admin feedback when an anomaly is labeled as “normal.” (The front-end for labeling anomalies is built by another team.) - Any labeled anomalies must be incorporated into future training (e.g., stored in PostgreSQL with updated labels) so the model learns from these corrections. 6) Simple HTML Dashboard - Provide a minimal HTML or web-based interface to view recent anomaly detection results with pagination. - Note: The advanced admin-labeling dashboard is out of this project’s scope, but we must expose an API to receive those labels. 7) Containerization - Package everything (data ingestion, inference workers, PostgreSQL, RabbitMQ, and the web UI) with Docker. - Supply a docker-compose.yml for simple, one-command startup. ACCELERATED 2-WEEK TIMELINE: Despite the complexity, this project must be completed within 2 weeks. Here is an accelerated plan: Week 1: - Day 1-2: Architecture & Setup • Finalize pipeline design: data flow, database schema, and Docker structure. • Spin up RabbitMQ and PostgreSQL containers; confirm connectivity. - Day 2-4: Data Ingestion • Implement REST API fetching and incremental storage in PostgreSQL. • Integrate logging and error handling. - Day 4-5: Initial Training Logic • Set up quick initial training on a sample or mock historical dataset. • Confirm model choice(s) for anomaly detection (e.g., Isolation Forest, HBOS, LOF, etc.). Week 2: - Day 1-3: Inference & Cross-Domain Anomaly Logic • Implement real-time ML inference triggered by RabbitMQ messages. • Incorporate user role logic and cross-domain correlations. - Day 3-4: Alerts & Web Dashboard • Raise alerts if anomalies are detected (publish to RabbitMQ or a separate channel). • Create a minimal HTML page to display recent anomalies (pagination required). - Day 4-6: Feedback API & Full Dockerization • Build an API to handle admin feedback (“this anomaly is normal”). • Incorporate labeled data into the training set for future retraining. • Finalize Docker images for each service; integrate them in docker-compose.yml. • Run integration tests to ensure everything works end-to-end. - Day 6-7: Refinements & Handover • Fix critical bugs, optimize performance if needed. • Provide final documentation (installation, model usage, re-training, troubleshooting). Note: Days refer to working days within the 2-week window. Tasks may overlap as needed to meet the deadline. REQUIRED SKILLS & QUALIFICATIONS: 1) Python & Data Engineering - Strong experience with Python (production-grade code). - Familiar with scheduled tasks, REST API integration, and PostgreSQL. 2) Machine Learning & Anomaly Detection - Hands-on experience implementing ML-based anomaly detection. - Skilled in cross-domain anomaly logic and incremental or batch re-training strategies. - Knowledge of user-role–based anomaly detection is a plus. 3) RabbitMQ (or Similar) - Proficiency with asynchronous, message-driven architectures. 4) Web Development - Able to build a minimal HTML/Flask/FastAPI UI for anomaly results (with pagination). - Understand how to build or expose APIs for external dashboards to call. 5) Docker & DevOps - Proven ability to containerize multi-service systems. - Proficiency writing Dockerfiles and docker-compose.yml. DELIVERABLES: 1) Code & Docker Setup - Python scripts for data ingestion, ML inference, auto-training, and the feedback API. - Docker images for each service, plus a single docker-compose.yml file to orchestrate everything. 2) PostgreSQL Schema - Designed to store user activities, anomaly outputs, and labeled anomalies for future training. 3) RabbitMQ Workflow - Producer (data ingestion) → Consumer (inference) → Alert channel if anomalies arise. 4) Feedback API - Receives admin-labeled anomalies (“this anomaly is normal”) from an external dashboard. - Updates the database and pipeline to leverage this feedback for future training. 5) Anomaly Detection Pipeline - Initial training plus real-time detection, storing results in PostgreSQL. 6) Minimal HTML Front-End - Displays recent anomalies in a paginated format. 7) Documentation & Handover - Setup & usage instructions (with Docker). - Guidance on re-training or adjusting models. - Basic troubleshooting tips. HOW TO APPLY: Please submit: 1) A brief summary of your relevant experience (emphasize any successful deliveries under tight deadlines). 2) Examples of prior work (e.g., Git repositories, demos, or references to similar anomaly detection or data pipelines). 3) An outline of how you plan to handle cross-domain data, user-role–based detection, and feedback integration within 2 weeks. 4) The tech stack and libraries/frameworks you propose to use. We’re looking for someone who can start immediately and deliver under intense time constraints. If you have the expertise and thrive in fast-paced projects, we look forward to your proposal!
