Let’s make your idea real.

Your product doesn't need another developer who ships fragile code and vanishes. It needs one who takes it from idea to production and keeps it standing after launch. That's what I do. I'm a Full Stack Developer (8+ years) who builds complete products: React/Next.js on the front, Node.js and Python on the back, AI woven in natively, for founders who need to ship fast without rebuilding in six months. I've shipped 10+ live products across fintech, healthcare, e-commerce, and education, including a legal-AI platform that helped its company raise $2M, and a learning platform now used by Yale, Tulane, and 600+ schools. Real products. Real users. Real revenue. Hire me and you get a React developer, Node.js developer, and Python developer in one: a true full-stack engineer who owns the whole build. I work across React / Next.js / TypeScript (frontend), Node.js, Express, and Python (FastAPI, Django) on the backend, and MongoDB / PostgreSQL for data. When a project needs AI, I integrate it natively with OpenAI and modern LLM tooling (RAG, vector databases, AI agents), built into the product, not bolted on as an afterthought. PROOF I SHIP REAL PRODUCTS: • DecoverAI: Legal document search platform. Python backend + React frontend, RAG retrieval over a vector database. Deployed in US law firms; the company raised $2M in seed funding after launch. • Speakology: Avatar-based language-learning platform. React/Next.js + Node.js + OpenAI voice. Adopted by 600+ schools and 12K students, including Yale University and Tulane University. Plus 8 more production apps: healthcare clinical screening, AI sales intelligence, supply-chain forecasting, hospital management, 3D-printing e-commerce, and more. All React / Node.js / Python full-stack builds. WHAT I DO: • Build complete web applications from scratch: React/Next.js frontend + Node.js or Python backend + database • Design and ship REST APIs, GraphQL, and third-party API integrations (Stripe, OpenAI, custom) • Build and scale multi-tenant SaaS platforms and MVPs from idea to launch • Migrate and refactor legacy code into clean, maintainable architecture, no rewrites • Add AI features to existing products: chat, semantic search, automation, RAG, LLM integration • Deploy and run apps on AWS with Docker and CI/CD STACK: Frontend: React, Next.js, TypeScript, JavaScript, Redux, Tailwind CSS Backend: Node.js, Express, Python, FastAPI, Django, REST APIs, GraphQL Databases: MongoDB, PostgreSQL, Redis AI: OpenAI API, LLM integration, RAG, vector databases, LangChain, AI agent development Cloud/DevOps: AWS, Docker, CI/CD HOW I WORK: I write code that matches your conventions, communicate clearly, and ship on schedule. Clients describe the work as "amazing… really dedicated and loves to think along about product improvements," and as understanding requirements quickly and delivering outstanding results. I think about the product, not just the ticket. Available 30+ hours/week and responding within a few hours. Tell me what you're building: a SaaS MVP, an AI-powered web app, an API integration, or a rescue of an existing codebase, and I'll tell you exactly how I'd build it.

It should be scalable, maintainable, secure, and easy to evolve as the business grows. I communicate clearly, move quickly, and focus on delivering production-ready solutions—not just prototypes. If you're looking for someone who can combine strong software engineering with practical AI implementation, I'd be happy to discuss your project.

I help teams build and improve Python backends for SaaS products and growing platforms, whether that means starting an MVP from scratch, integrating AI capabilities, or improving an existing production system. Most of my work involves owning backend systems: reviewing code, fixing performance issues, migrating services, designing scalable APIs, and making sure applications stay stable as they grow. I mainly work with Python, Django, FastAPI, Flask, and AWS, while selecting the right architecture and tools based on the actual business problem and computer vision solutions for image processing, detection, and AI-based analysis and AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation. Moreover, I have been working as a Python developer for 8+ years, supporting real production systems across different industries. I’m comfortable building new features, cleaning up legacy code, integrating AI/ML solutions, and handling the important engineering work that keeps systems reliable. What I usually work on: Python backends using Django, FastAPI, and Flask SaaS platforms & MVPs (early builds → production) Microservice migrations and backend restructuring REST API development and third-party integrations Code reviews, refactoring, and performance optimization Databases like PostgreSQL, MySQL, and MongoDB Background jobs with Celery, Redis, and RabbitMQ Deployments and scaling on AWS AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation Computer Vision solutions for image processing, detection, and AI-based analysis Key Projects: Touringery: Multilingual tour booking APIs → improved booking throughput by 50%. Moeving EV: Fleet tracking microservices → real-time data processing for 500+ vehicles. Kera Health: Healthcare backend handling patient data, appointments, and AI-powered diagnostics. Healthcare AI Diagnostics: Integrated ML models for automated patient reporting and intelligent insights. AI Chatbots & NLP Systems: Built LLM-powered conversational solutions, knowledge retrieval systems, and AI automation workflows. I work well independently or with a team, communicate clearly, and take ownership of the backend and AI systems I build. I’m available 40+ hours per week and can overlap with US and European time zones. If you’re looking for someone who can step into your backend, improve your systems, and build scalable AI-powered solutions, "just click Invite" I usually reply within a few hours.
