MVP Developer: AI Personal Assistant (Voice, Email & Calendar Automation - CrewAI, LangGraph, AG-UI)
Job Description:
We are seeking a highly skilled and motivated AI/Full-Stack Developer or a small, agile team to partner with us in building the Minimum Viable Product (MVP) for an innovative AI Personal Assistant. This is not just another chatbot; we are creating a sophisticated agent designed to learn from user communication patterns and calendar behavior to take autonomous action, much like a human executive assistant. The goal of this MVP is to demonstrate core functionalities including multi-modal command execution (voice and text), intelligent email automation (reading, identifying, drafting context-aware replies based on a learned "communication profile," and sending after approval), smart calendar management (availability checks, event creation, conflict resolution), and asynchronous task preparation (e.g., proactively drafting emails). A key component will be an interactive user dashboard for approving actions, viewing real-time agent activity, and basic configuration, all underpinned by a modular agent architecture (CrewAI, LangGraph) and standardized frontend-backend communication using the AG-UI protocol.
Core Responsibilities & MVP Scope:
The successful candidate(s) will be responsible for the end-to-end development of this MVP, working in close collaboration with the company founder.
On the backend (FastAPI, Python), you will implement the agent orchestration using CrewAI and LangGraph. This includes a Main Delegator Agent and specialized agents for Email Processing (reading, identifying context), Communication Profile Management (analyzing past emails via Supabase/pgvector to build a user's communication style profile for email drafting), Email Drafting (using LLMs like GPT-4o-mini), Calendar Management (Google API integration), and an Asynchronous Task Agent (initially focused on proactive email drafting). You will develop approval workflows using LangGraph (e.g., Draft Email, User Approval, Send Email). A crucial part will be implementing the server-side of the AG-UI protocol for event-driven communication with the frontend, including streaming text, handling tool calls (e.g., requestUserApproval, executeGmailAction), and emitting state updates for the dashboard. You'll also build necessary API endpoints, manage database interactions with Supabase/PostgreSQL (including pgvector for embeddings), and integrate ElevenLabs for streaming voice STT/TTS.
On the frontend (Next.js, React), you will develop the user interface, including a chat interface for text/voice commands (using RecordRTC) and a comprehensive dashboard. The dashboard will feature an "Action Center" for users to approve/deny agent-proposed actions (like email drafts or meeting creations), an "Agent Activity Log" providing real-time visibility into what agents are doing (powered by AG-UI state events), a viewer/editor for the user's "Communication Profile," and basic agent configuration settings. You will implement the client-side of the AG-UI protocol (likely over Socket.IO) to handle event streams, manage UI updates, and define/execute frontend logic for AG-UI tools requested by the backend. State management (SWR or similar) and full integration of Supabase Auth (Email/Pass + Google OAuth) for secure user login and API communication are also key.
Key Deliverables:
The primary deliverable is a fully functional MVP encompassing the features described above, including all source code. This includes a modular agent system ready for future expansion (e.g., easily adding new agents to CrewAI). While the founder will handle final deployment, the system must be demonstrably deployable and working. Basic unit tests for critical backend logic and frontend components should be set up, alongside thorough functional testing of all features.
Required Skills & Experience:
We are looking for individuals or teams with strong proficiency in Python/FastAPI and React/Next.js. Demonstrable experience with AI agent frameworks like CrewAI and LangGraph (or very similar tools) is essential, alongside experience integrating LLM APIs (OpenAI preferred). You should be comfortable with PostgreSQL (Supabase a plus), vector databases (pgvector), implementing OAuth 2.0 (Supabase Auth a plus), and real-time communication via WebSockets (Socket.IO preferred). Familiarity with the AG-UI protocol or a proven ability to quickly learn and implement its event-driven patterns is a significant advantage. Experience integrating third-party APIs like Google Workspace and ElevenLabs, a commitment to writing clean, modular, and well-documented code, and excellent communication skills for a highly collaborative environment are also required.
Project Details & Collaboration:
This is an intensive, collaborative project with an estimated timeline of 1 month and a budget of up to $5000 USD. You will work side-by-side with the founder, participating in daily check-ins and joint problem-solving. The founder will provide guidance, feedback, and can assist with aspects like Supabase setup and deployment. Successful completion of this MVP with high-quality work opens the door to significant future opportunities, including ongoing development work, the potential for a full-time role, and equity discussions.
To Apply:
Please submit a brief cover letter detailing your specific experience with CrewAI, LangGraph, and any similar AI assistant or agentic system projects. Include examples of previous work that showcase your capabilities in the required skill areas. We'd also appreciate your initial thoughts on tackling the "Communication Profile Agent" and its learning aspect for the MVP, and confirmation of your availability for the next month. We look forward to hearing from you!
Client's questions:
  • Please describe any relevant experience you have and why you believe you or your team will be the best fit for this job.
  • Include a link to your GitHub profile and/or website

Job Overview
I’m building a RevOps data management system that uses Supabase as the central database, acting as the source of truth between HubSpot (CRM) and Clay (enrichment platform). We need an experienced backend or API-focused developer to help build a few lightweight scripts and webhook handlers that support two-way data sync between these systems.

Deliverables
1. HubSpot to Supabase sync script
Pull contacts and companies from HubSpot

Store/update them in Supabase tables (contacts, companies)

Use lastModifiedDate for incremental sync

Handle pagination and rate limits

2. Supabase to HubSpot sync script
Monitor records in Supabase with recent changes

Push updates back to HubSpot via their CRM API

Only update if Supabase values differ from HubSpot

Include basic deduplication and error logging

3. Clay webhook handler
Create a webhook endpoint to receive enrichment data from Clay

Parse incoming payload

Match enriched record to existing Supabase record by email/domain

Update properties in contacts or companies tables

4. (Optional) Supabase to Clay sync/export
Export a filtered view of records to a CSV

Prepare for manual or API-based import into Clay

Automate this via a cron job or endpoint trigger

Tech Requirements
JavaScript/TypeScript or Python (your choice)

Experience with REST APIs (HubSpot, Supabase, ideally Clay)

Comfortable working with PostgreSQL and Supabase

Knowledge of webhooks, cron jobs, and error handling

Optional: Supabase Edge Functions or deployment on Vercel/Render

Project details
MVP stage — you’ll be building reusable scripts, not a full UI

We’ll provide API keys, Supabase schema, and sample records

Expectation is clean, modular code with good logging and comments

Database size: 100K+ records, 100–200 properties per object

Potential for long-term work if MVP succeeds

How to Apply
Briefly explain your experience with similar API integrations or Supabase

Mention any relevant projects (especially HubSpot or CRM integrations)

Company Name: COSIE
Job Description:
We are looking for a freelancer with strong experience in AWS Lambda, Prisma ORM, and PostgreSQL to help us resolve deployment issues with our Node.js application.
The Problem:
Our application is successfully deployed on AWS Lambda, but we're facing issues with Prisma ORM. Specifically, we receive the following error:

PrismaClientInitializationError: Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x"
PrismaClientInitializationError: Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x".

This is likely caused by a bundler that has not copied "libquery_engine-rhel-openssl-3.0.x.so.node" next to the resulting bundle.
Ensure that "libquery_engine-rhel-openssl-3.0.x.so.node" has been copied next to the bundle or in "../../node_modules/.pnpm/@prisma+client@6.6.0_prisma_d3fe9aa60353bd2d0fe07784257bd634/node_modules/.prisma/client".

We would appreciate if you could take the time to share some information with us.
Please help us by answering a few questions: https://pris.ly/engine-not-found-bundler-investigation

The following locations have been searched:
/node_modules/.pnpm/@prisma+client@6.6.0_prisma_d3fe9aa60353bd2d0fe07784257bd634/node_modules/.prisma/client

/tmp/prisma-engines","reason":{"errorType":"PrismaClientInitializationError","errorMessage":"Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x".

Prisma Engine is correct and located where it should be, still getting this error

We need a solution to this issue so that our app can successfully interact with the PostgreSQL database without any issues.
Key Requirements:
Experience with AWS Lambda deployment and serverless architecture.
Proven experience with Prisma ORM and PostgreSQL database in AWS environments.
Familiarity with AWS services, especially RDS, VPC, and IAM for managing cloud infrastructure.
Ability to troubleshoot and fix Prisma errors related to deployment on Lambda.
Strong communication skills and the ability to provide solutions in a timely manner.
Responsibilities:
Resolve the Prisma Client initialization error while maintaining the app’s compatibility with PostgreSQL.
Ensure that the database is correctly set up in the AWS environment and Lambda can communicate with it securely.
Provide clear, concise updates throughout the process
Application Process:
Please submit your proposal with your relevant experience, especially in deploying serverless applications using AWS and Prisma ORM.
Include any previous work examples or projects where you solved similar issues.

Budget: ₹10000

We are looking forward to working with a skilled freelancer who can help us fix these deployment challenges. If you think you're a good fit for this job, please feel free to apply.
