I am a FULL STACK ENGINEER with strong experience in building scalable, cloud-based applications using ReactJs, NextJs, JavaScript, Python, Ruby, AWS, NodeJS, NestJS, MongoDB, Stripe, Twilio, OpenAI, iElevenLabs and more. Over the past few years, I have led the development of froentend & backend systems for web and mobile apps, including a social media platform MVP where I designed and implemented serverless architecture using AWS Lambda, API Gateway, S3, and DynamoDB. This allowed the platform to scale smoothly and stay cost-effective. My core strength lies in designing RESTful APIs, setting up database structures, and writing clean, efficient code that performs well even under high traffic. I regularly work with MongoDB and have a solid understanding of database design, indexing, and query optimization. I also have hands-on experience in authentication systems, role-based access control, and integrating third-party APIs. I enjoy solving complex problems and making backend systems faster, more secure, and easier to maintain. I’m comfortable working independently or with cross-functional teams, and I often collaborate with frontend developers to ensure the entire application works smoothly from end to end. While my main focus is backend, I also have experience with React, which helps me understand how backend and frontend connect. If you're looking for someone who can take ownership of the end to end development, set up reliable cloud infrastructure, and deliver robust and well-documented APIs — I’d love to help.

9+ years of full-stack engineering experience, with a focus on AI integrations, scalable SaaS architecture, and production system reliability. I help product teams and founders build AI-powered web applications that are stable, maintainable, and ready for real users — not just demos that work in development. Best fit: LLM integrations, RAG pipelines, AI agent workflows, SaaS backend architecture, real-time systems, RBAC design, and technical rescue work. I work well with clients who need clean API design, reliable backend systems, secure authentication flows, and long-term code maintainability. ------------------------------------------------------------ Core Areas AI and LLM Engineering: RAG pipeline design and optimization, LLM integrations (OpenAI, Claude, Gemini), AI agent workflows, multi-agent orchestration, semantic search, vector databases, prompt engineering, token cost optimization, and production AI debugging. Software Architecture: Multi-tenant SaaS platforms, RBAC and permission systems, event-driven backends, modular monolith and microservice design, API-first architecture, codebase audits, and technical rescue work. Backend Engineering: NodeJs, NestJS, Express, TypeScript, REST APIs, WebSockets, JWT Auth, Queue systems, Serverless functions Frontend Engineering: NextJs, React, TypeScript, Tailwind CSS, Material UI, Server Components, App Router Databases and Storage: MongoDB, PostgreSQL, Redis, Supabase, Firebase, Prisma, Mongoose, Vector databases (Pinecone, pgvector, Qdrant) Cloud and DevOps: AWS Lambda, Docker, CI/CD pipelines, Serverless architecture, Environment management and production deployment ------------------------------------------------------------ Relevant Experience: AI-powered SaaS platforms with LLM features, semantic search, and document processing pipelines built for production workloads. RAG systems with retrieval tuning, chunking strategy, embedding pipelines, and accuracy optimization across real datasets. Multi-agent orchestration workflows using Claude and OpenAI APIs with structured output, fallback handling, and observability. Multi-tenant SaaS backends with role-based access control, scoped data isolation, and subscription-aware APIs. Real-time applications using SocketIo and WebSockets for live collaboration, notifications, and event-driven features. Full-stack bill management and invoicing platforms built with NextJs, Supabase, and customizable document templates. Serverless backend systems on AWS Lambda with TypeScript, MongoDB, JWT token rotation, and CI/CD integration. RBAC engine design with modular architecture, Drizzle ORM adapters, Auth0 integration, and NestJS API layer. ------------------------------------------------------------ I think like an architect, but I still write the code. I care about clean data flow, proper error handling, security by design, and systems that the next engineer can understand without a guided tour. I do not build fragile prototypes. I build production systems that survive real users and can be maintained after launch. If your project needs an engineer who can understand the product, identify technical risk early, and ship reliable software — let's talk.
