I have been on the founder side myself, which means I understand your budget, your deadline, and what done actually means for a real business.
If you're reading this, you probably have one of these problems:
You have a great idea, but need an MVP built fast without sacrificing quality
Your current codebase is slow, messy, or falling apart under scale
You need AI integrated into your product (OpenAI APIs, RAG pipelines, vector search), and most devs don't really get it
You've been burned by developers who vanished or delivered something unusable
I solve all four.

Full-stack AI developer with 𝟭𝟬𝟬% 𝗝𝗼𝗯 𝗦𝘂𝗰𝗰𝗲𝘀𝘀 𝗮𝗻𝗱 𝟴 𝗳𝗶𝘃𝗲-𝘀𝘁𝗮𝗿 𝗿𝗲𝘃𝗶𝗲𝘄𝘀 ⭐⭐⭐⭐⭐. I build AI chatbots, OpenAI-powered web apps, and REST APIs for startups and SaaS businesses; React, Node.js, Next.js, from idea to deployment.
Most AI projects fail because they're built without context or strategy. I help businesses choose where AI actually makes sense, design the right architecture, and integrate it securely into existing systems; so you get results, not just a prototype that breaks in production.

Hello there 🤝
I am a full-stack developer with 6+ years of experience building scalable web apps, SaaS platforms, and AI-powered products from scratch to production.
I specialize in both:
working as part of engineering teams, contributing to existing codebases and product development
and taking full ownership of building applications from idea to production (architecture, development, deployment, and scaling)
My focus is always on building real, production-ready software that solves business problems — not just prototypes or demo applications.
🧠 What I build:
I help startups and companies design and develop:
SaaS platforms (multi-tenant, subscription-based systems)
AI-powered web applications and automation tools
MVPs for early-stage startups (fast and scalable)
Dashboards, admin panels, and internal tools
API-driven platforms and client portals
Real-time systems and workflow automation tools
Tech Stack:
Frontend
React, Next.js, TypeScript, JavaScript, Redux, HTML, CSS, SCSS, Tailwind CSS, Material UI, Ant Design
Backend:
Node.js, NestJS, Express.js, REST APIs, GraphQL (Apollo), WebSockets (Socket)
Databases:
PostgreSQL, MongoDB, MySQL, SQLite, DynamoDB, Supabase, Firebase (Firestore, Realtime DB)
Cloud & DevOps:
AWS, GCP, Vercel, Cloudflare, Docker, CI/CD (GitHub Actions)
Authentication & Integrations:
JWT, OAuth2, Auth0, Firebase Auth, Stripe, PayPal, Webhooks
AI & Modern Development Tools:
I use modern AI-assisted development tools to increase productivity and shipping speed:
Cursor IDE
Claude Code / Claude AI
ChatGPT (OpenAI API integration & engineering assistance)
GitHub Copilot
AI-assisted debugging, refactoring, and code generation workflows
I also integrate AI features directly into products:
OpenAI API (GPT-based systems)
AI automation workflows
intelligent backend logic and assistants inside SaaS products
How I work:
join an existing engineering team and contribute immediately
take ownership of a feature, module, or full product area
build applications completely from scratch (architecture → deployment → scaling)
I focus on:
clean and scalable architecture
maintainable and production-ready code
performance and system reliability
fast and structured delivery
Additional expertise:
Real-time systems (WebSockets, Socket, Pub/Sub architecture)
WebRTC and streaming applications
Chrome extensions (TypeScript-based)
CMS integrations (Strapi, Contentful)
Performance optimization and system refactoring
AI-powered automation systems
My goal:
To help startups and teams turn ideas into scalable software products and AI-powered platforms — and to contribute as a reliable full-stack engineer who can work independently or as part of a product team.
If you're looking for someone who can build or scale your SaaS, AI product, or web platform from idea to production - feel free to reach out.

One of my clients just closed $1M in seed funding on a SaaS platform I built. Another is running a live AI agent inside medical practices, fully HIPAA compliant. I am a Full Stack AI Engineer with 8 years of experience and 20+ AI and SaaS products shipped. If that is what you need, keep reading.
Most AI projects fail between the demo and production. The agent works in a sandbox, the RAG pipeline pulls wrong context in the real environment, and the SaaS MVP that looked perfect in staging cannot handle actual users. That gap is what I close.
IBM and Meta certified |Top Rated. FinTech, MedTech, and EdTech.
Here is what I build and what it actually does for your business:
AI Agents and Multi-Agent Systems using LangGraph, LangChain, and CrewAI that execute real business workflows so your team stops doing manually what a system should handle automatically.
2. RAG systems that stop your AI from giving wrong answers to paying customers. Hybrid retrieval, re-ranking, and evaluation pipelines built on Pinecone, pgvector, and ChromaDB.
3. SaaS MVPs and multi-tenant SaaS platforms with auth, Stripe billing, role-based access, and admin dashboards that go live in weeks, not quarters.
4. AI workflow automation connecting n8n, Make, and Zapier to LLM backends that permanently replace manual processes across your operations
5. Production deployments on AWS, GCP, and Supabase with Docker, CI/CD, and observability built in from day one, not patched in after something breaks.
Two products I shipped recently:
Dandalee is a procurement SaaS platform for the Architecture, Engineering, and Construction industry. Built end-to-end on Next.js, Express.js, and n8n automation. It onboarded 2,000+ sellers, closed a $50K bridge round, and secured $1M in seed funding in Q1.
Doclatch is a HIPAA-compliant AI healthcare assistant built on LangChain and FastAPI. It parses unstructured medical documents, extracts clinical context, and generates structured staff task cards with source-level citations so every AI output is liability-proof for the practice.
Stack:
AI & LLM: OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, MCP, Function Calling, Model Routing, AI Agents, Multi-Agent Systems, AI Copilots
RAG & Search: RAG, Embeddings, Semantic Search, Pinecone, pgvector, ChromaDB, Document AI, OCR
Automation & Reliability: n8n, Make, Workflow Automation, Human-in-the-Loop Systems, Evaluation Frameworks, Hallucination Reduction
Frontend: Next.js, React, TypeScript, Tailwind CSS
Backend: Python, FastAPI, Django, Node.js, NestJS, REST APIs, GraphQL, WebSockets
Databases: PostgreSQL, Supabase, Redis, MongoDB
SaaS: Multi-Tenant Architecture, Tenant Isolation, RBAC, Admin Dashboards, Stripe Billing
Cloud & DevOps: AWS, Docker, Vercel, CI/CD, Monitoring
Security: OAuth2, JWT Authentication, Encryption, Audit Logs
Voice AI: Vapi, Retell AI, ElevenLabs, Deepgram, OpenAI Realtime API, Twilio
Integrations: Stripe, Plaid, Open Banking APIs, QuickBooks, Xero, CRM Integrations, ERP Integrations
If you are building an AI agent, RAG system, SaaS MVP, or full stack AI product and need it to work in production, message me with what you are trying to build. I will tell you in the first reply whether it is feasible, what the architecture looks like, and roughly what it costs. No sales call needed to get a real answer.
