Familiarity with vector databases
Previous work on AI chatbots or customer automation systems

Contract Details

Long-term/ongoing project (more than 6 months)
Hourly contract
Work from home, but developers will remote login (via secure VPN + company-managed access) into a US-based development computer for all work
Flexible working hours

We will start with a small paid test task to evaluate the collaboration before moving forward with a longer-term contract.
If you’re a full-stack Java developer excited about building production-grade AI systems using modern tools and AI assistants, we would love to hear from you!
Please apply with relevant project links (especially any AI/LLM/RAG work) and your expected hourly rate.

We are a Minneapolis-based SaaS Electronic Health Record (EHR) company. We are embarking on a massive greenfield rebuild of our platform—migrating our active user base from a 15-year-old legacy Java 1.7 monolith into a modern, highly scalable, and HIPAA-compliant architecture.

The Project:
We are sunsetting our old code and building a brand-new platform using Java 21, Spring Boot 3, React, and GCP.

We are looking for a Lead Java Architect / Senior Backend Engineer to partner directly with our CEO/Product Owner. You will own the core backend architecture, database normalization, and cloud infrastructure from initial build through production release. (Note: We are also hiring a dedicated UX/UI designer and a mid-level React developer to handle the frontend, allowing you to focus heavily on the database, APIs, and system architecture).

Core Responsibilities:

Legacy Extraction & Modernization: Safely untangle and extract business logic from a Java monolith.

Database Architecture: Map and migrate our existing highly denormalized MySQL database into a clean, modern, 3NF normalized relational database structure.

API Development: Build a robust library of Spring Boot REST APIs to power our new React frontend.

Cloud Infrastructure: Set up secure, HIPAA-compliant cloud infrastructure (GCP or AWS) and reliable CI/CD deployment pipelines.

Data Integrity: Ensure absolutely zero data loss or corruption of patient ePHI and financial ledgers during the migration.

Healthcare Integration: Support backend logic for healthcare-specific functions (e.g., ANSI 837 claim generation, 270/271 eligibility parsing).

Required Skills & Experience:

Deep Java Expertise: You must be comfortable reading legacy Java and writing modern Enterprise Java (17/21) using Spring Boot 3 and Spring Security.

Database Mastery: Advanced SQL skills, schema design, and experience breaking apart legacy monoliths into scalable architectures.

Cloud & DevOps: Proven track record of setting up secure, regulated environments (HIPAA or Finance) in GCP or AWS.

Bonus Points: Previous experience building EHRs, EMRs, or working directly with EDI healthcare billing payloads.

How to Apply:
We are looking for a true partner who wants to own a critical system end-to-end, not just clear Jira tickets.

To ensure you have read this description and understand the scope of the work, please start your proposal with the answer to this question:

"How would you approach migrating a live, 15-year-old Java 1.7 monolith and a flat database into a 3NF normalized Spring Boot API without breaking the current production system or losing patient ePHI?"

Please include your hourly rate, availability, and a brief overview of similar modernization projects you have completed.

I am seeking a skilled developer to create a trading bot. I will provide the strategies, and I am open to suggestions from interested developers. The ideal candidate should have experience in trading bot development and be able to implement the strategies effectively. If you are interested in this project, please connect with me to discuss further details.

Requirements and specifications:

1- The application must be compatible with the GS web application through synchronization with the same database.

2-The application should work without needing the internet connection.

3-The application should support point of sale system Supports screen size 15.6 inch + screen with an 8 digital customer price display (customer price display - quick printing of the invoice when pressing the payment button - opening the cash drawer at the same time as printing the invoice).

4- The application is controlled through a web application system.(Verify the accuracy of the login data by checking the account status/customer license/subscription expiry date/subscription type.)

5- All data is matched between the web application and the Android application through synchronization.(Add/Edit/Delete....etc)

Note: The application will be on the seller's device, so it must contain everything the seller needs from the web application system, and application management will be through the web application.

The ideal candidate will have experience in AI automation and cloud computing, with a strong understanding of API integration and HTTP request management.

We have a web app currently built on Base44, an AI app-building platform. It works well for prototyping, but Base44 runs on shared infrastructure with no SLA, limited backup control, and no real authorization auditing — so before this app goes live with real client data, we need it migrated to infrastructure we own and control.

The app is a customer-facing tool that lets users submit a lookup request and pay via Stripe. Frontend is React (exported via Base44's GitHub sync). We're looking for a developer who has done this kind of migration before, or who is very comfortable with Supabase and can move quickly without breaking what already works.

Scope of work:

Review the exported Base44 codebase (React/Vite) and the existing GitHub repo.
Export all data currently stored in Base44 and recreate the schema in a new Supabase project.
Set up Row Level Security on every table, with proper ownership checks (not just "is logged in") — this is the most common gap in Base44 apps and the priority item.
Replace Base44 SDK calls throughout the codebase with Supabase client calls.
Reimplement any backend logic currently running as Base44 functions (including the Stripe payment flow) as Supabase Edge Functions.
Add rate limiting on any endpoint that triggers a paid API call or a Stripe charge.
Add proper error handling on all API, database, and third-party integration calls — no silent failures.
Review data-fetching patterns for N+1 queries and inefficient calls; add indexes where needed.
Move any hardcoded keys or secrets into environment variables / a secrets manager.
Deploy the frontend to Vercel on our custom domain, with CI/CD through the existing GitHub repo.
Provide short documentation covering environment setup, deployment, and a checklist confirming each item above is addressed.

Must-haves:

Strong hands-on experience with Supabase (Postgres, RLS policies, Edge Functions, Auth)
Solid React/Vite experience
Experience deploying and configuring CI/CD on Vercel
Experience integrating Stripe
Comfortable reviewing and securing AI-generated code
Can explain tradeoffs clearly to a non-technical stakeholder

Nice-to-haves:

Prior experience migrating an app off Base44, Bubble, Lovable, or a similar no-code/AI builder
Experience with small business or agency client tools

Deliverables:

Fully migrated app live on Vercel + Supabase, functionally equivalent to the current version
RLS and authorization confirmed working (not just configured)
Written handoff doc for future maintenance

To apply, please briefly describe how you'd approach auditing and fixing authorization/RLS issues in an AI-generated app, and share an example of past Supabase work if you have one.

Create a link to grab an approximate location of IP address without a warning message. I am seeking this to target location of someone that clicks on it as I am seeking where to market my business.
I would like it to be ending with a .jpg and be able to click and see who views it.
Please let me know if you need more information.

About the role
A hybrid Product Manager / DevOps owner for infra and product managment. Can be full time. You write the PRD specs, then make sure the systems behind them run reliably, securely. You need to use AI to move fast on both product and code alongside the development team.

When applying for this role, please note we will require you to do a live test with us, and be serious when applying, don't just send templated AI written proposals. Proof out that you really can do it.

Details:
Product Management
• Build the roadmap with the product team: write PRDs, groom sprints, validate delivered features.
• Facilitate requirements discovery and bridge technical feasibility with product value.
• Drive product and coding through AI, working hand-in-hand with the dev team.
