Full Stack Developer with 6+ years shipping production SaaS: React and Next.js on the front, Node.js and NestJS APIs behind it, PostgreSQL, MySQL and MongoDB under that, AWS and DigitalOcean on top, and AI (OpenAI, RAG, AI agents) where it actually earns its place. I build complete web products and stay for the boring parts after launch. 20+ shipped apps across fintech, e-commerce, enterprise ERP, and AI SaaS. Most clients hire me because they do not want to stitch together a frontend person, a backend person, and an AI person. 🚀 What I build: - Full-stack web apps and SaaS: Next.js and React front ends, Node.js or NestJS APIs, PostgreSQL or MongoDB, deployed on AWS, DigitalOcean, or Vercel. - Backend and APIs: REST and GraphQL API development, authentication, microservices, background job pipelines with BullMQ and Redis, real-time features with Socket io and WebRTC. - AI-native products: RAG and document chat, AI agents and multi-agent orchestration, OpenAI, Claude, and Gemini integrations, vector search, streaming AI responses, embeddable AI widgets. - Payments and billing: Stripe, Stripe Connect marketplace payouts, subscriptions, usage and credit based billing, Razorpay, PayPal. - Legacy rescue and migrations: modernizing old systems onto a current stack without taking the business offline. 🛠 Technical stack: - Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS, Redux, shadcn/ui. - Backend: Node.js, NestJS, Express.js, Python, Laravel, REST APIs, GraphQL, microservices. - Databases: PostgreSQL, MySQL, MongoDB, Redis, ClickHouse, Oracle, ChromaDB, Supabase. - AI: OpenAI API, Anthropic Claude, Gemini, Vercel AI SDK, RAG pipelines, vector search, AI agents, Mem0. - Cloud and DevOps: AWS (EC2, Lambda, S3, SQS, IVS), DigitalOcean, Vercel, Docker, CI/CD. - Developer flow: Cursor Pro and Claude Code (Max plan) built directly into my daily work. 📊 Milestones and shipped work: - High-traffic scale: run production systems handling 10M+ requests a day, with databases up to 7B+ rows, under long-term SaaS contracts. - Cloud cost: cut server infrastructure cost by half with zero downtime (one DigitalOcean setup went from $1,600 to $700 a month), and reconfigured AWS SQS to drop monthly queue cost by 90%. - Performance: cut API latency by 90% on a legacy platform that was buckling under load, from around 1.5 seconds to 50-150ms. - KitchenCloud.AI: built the multi-agent orchestration layer routing to 6 specialized sub-agents with vector search and persistent memory, for an agentic AI kitchen assistant. - Enterprise ERP migration: ran a zero-downtime legacy migration to NestJS, Next.js, and Oracle for a NASDAQ listed US corporation, leading the core backend integration team. - StockPe: built on a fintech platform now serving 300,000+ active users that reached #2 Product of the Day on Product Hunt. - E-commerce and apps: shipped live applications on the Shopify App Store (including Aura AI) using the GraphQL Admin API and custom search architectures. On Upwork I am Top Rated with 100% Job Success and 2,260+ hours billed, and every review so far is 5 stars. One client put it as "delivered much faster than expected with higher quality than asked for." I am available now for 30 to 40 hours a week, I overlap with US and EU hours, and I reply the same day. If you want, send me your idea or your existing repo and I will tell you honestly what it needs before you hire anyone. Let's build something that works in production, not just in a demo.

I build software systems and automations that work as one. I am a Software Development Engineer with 3+ years of expertise in building and maintaing production grade systems and automations. I help businesses build reliable software, automate repetitive operations, connect their tools, and turn messy workflows into structured systems. My work sits at the intersection of full-stack development, automation, and systems design. Whether you need a web application, an internal tool, a complex automation, or several platforms connected through APIs, I focus on building the entire system, not just one isolated piece. I don't just deliver features or individual Zaps. I design end-to-end systems that are reliable, scalable, maintainable, and easy to reason about. What I Work With: Development ▪ Node.js, TypeScript, Express, NestJS ▪ PostgreSQL, SQL, REST APIs ▪ Full-stack web applications ▪ Backend systems and internal tools ▪ API integrations and webhooks ▪ Data modeling and system architecture Automation & No-Code ▪ Notion - advanced databases, relations, and business systems ▪ Zapier and Make (Integromat) ▪ Airtable, Monday, HubSpot, and other business tools ▪ Webhooks and API-based integrations ▪ Multi-step workflow automation ▪ Cross-platform data synchronization Systems & Workflow Design ▪ Data modeling and integrity ▪ Workflow architecture ▪ Automation reliability and error handling ▪ Process optimization ▪ Connecting disconnected tools and systems ▪ Replacing manual processes with structured workflows How I Can Help: ▪ Build full-stack applications and internal tools ▪ Design backend systems and APIs ▪ Automate repetitive business operations ▪ Build advanced Notion-based systems ▪ Connect your tools through APIs and webhooks ▪ Automate workflows using Zapier or Make ▪ Design reliable data flows between multiple platforms ▪ Replace manual processes with scalable systems Why Clients Work With Me: ▪ Engineering + automation: I can work across both traditional software development and no-code automation. ▪ Systems thinking: I look at the entire workflow rather than solving one isolated task. ▪ Logic-first approach: I care about how data, processes, and systems interact. ▪ Reliability over quick fixes: Automations should continue working when something unexpected happens. ▪ Long-term thinking: I build systems that can be maintained, extended, and understood as your business grows. If you need someone who can build the product, connect your tools, and automate the operations around it, you're in the right place.
