I’m a Senior AWS Backend & MLOps Engineer with 7+ years of experience building production-grade backend systems and ML automation pipelines from scratch. I help startups and teams design scalable APIs, data pipelines, and MLOps workflows using FastAPI, Flask, Airflow, and AWS, with a strong focus on reliability, performance, and clean architecture. I’ve worked extensively with PostgreSQL, MySQL, ClickHouse, and built internal tools and dashboards . I’m comfortable owning systems end-to-end—from architecture and development to deployment and automation in production.

I build web and mobile products that ship, scale, and stay maintainable. Over the past year I've taken SaaS platforms from early-stage to production, led small dev teams, and integrated AI features that actually move the needle. On the backend I work with Node.js, Django, and FastAPI, designing REST APIs, handling database architecture across MongoDB, PostgreSQL, and Supabase, and wiring up third-party integrations including Stripe Connect, OpenAI, and payment systems. On the frontend I build with React, Next.js, and React Native, delivering interfaces that are fast, responsive, and clean across web and mobile. For infrastructure I deploy on AWS EC2, manage containerized environments with Docker, implement CI/CD pipelines, and handle Redis caching for high-performance systems. For browser automation and scraping I use Puppeteer. On the AI side I've integrated LLMs, LangChain workflows, voice assistants, chatbots, and real-time AI-driven features into production applications. I approach LLM prompt engineering practically, building prompts that produce reliable, production-grade outputs rather than impressive demos. I've shipped an AI-powered accessibility SaaS platform, a cross-platform ride-sharing app, a production EHR system, and an HRM platform managing payroll and onboarding workflows. Real products, real users, real deadlines. If you need someone who takes ownership, reads an existing codebase quickly, and delivers without hand-holding, let's talk.

I build production-grade algorithmic trading systems and scalable trading platforms for traders and fintech teams who care about capital protection, execution quality, and long-term stability.

I build entire products, not just features. From database design to deployment pipelines, I handle the complete journey of turning ideas into working software. Started my career fixing a production server that crashed during Black Friday. That baptism by fire taught me something crucial: good code is just the beginning. Real value comes from understanding the entire system – how users interact with your frontend, how data flows through your backend, and how everything stays running when traffic spikes. ✦ What full stack means to me: It's not about knowing every technology (nobody does). It's about connecting the dots. When your React component is slow, sometimes the fix is in your MongoDB indexes. When your API times out, maybe it's your Nginx configuration. I debug across the entire stack because problems rarely respect boundaries. ✦ Technologies I work with daily: → Frontend • React • Next.js • JavaScript, TypeScript • Redux toolkit, Zustand • Tailwindcss, Shadcn ui, MUI and other • Whatever UI library makes sense for your project. I write interfaces that feel fast even on slow connections. → Backend ↳ For JavaScript projects; • JavaScript • TypeScript • Node.js • Express • Aggregation Framework ↳ For Django/DRF projects; • Python • Django & Django REST Framework • Django/DRF → Databases ↳NoSQL; • MongoDB • Mongoose. ↳SQL; • PostgreSQL • MySQL. → Others REST APIs, GraphQL servers, and real-time systems with Socket.io. PostgreSQL, MongoDB, Redis – I pick databases based on your data, not trends. → DevOps Docker containers that actually work in production, CI/CD pipelines that don't break every Tuesday, AWS/GCP deployments that don't cost a fortune. I automate the boring stuff so we can focus on building features. ✦ Real projects I've shipped: ↳ Built a food delivery platform handling 50K daily orders (MERN + Redis for caching) ↳ Created a learning management system for 100K students (Django + React + AWS) ↳ Developed a real-time analytics dashboard that processes millions of events (Node.js + ClickHouse + WebSockets) ↳ Set up auto-scaling infrastructure that saved a startup $30K/month in cloud costs My approach: I start by understanding your business, not your tech stack. Sometimes the best solution is a simple Express server. Sometimes you need microservices. I've seen both over-engineered MVPs and under-engineered enterprise apps. I'll tell you what you actually need. I write code like someone else will maintain it (usually future me). Clear variable names, useful comments, and documentation that actually helps. I've inherited enough mysterious codebases to know better. ✦ The truth about full stack: Nobody is equally good at everything. My strength is connecting pieces and making them work together. I can build your entire MVP solo, or I can jump into your team and fill whatever gap is slowing you down. Need someone to dockerize your app? Set up monitoring? Build that complex dashboard? Debug why your server crashes at 3 AM? I've done it all. If you want someone who asks "why" before "how" and delivers solutions that work in the real world, reach out. Tell me what you're building and what's keeping you up at night. I'm here to make those problems go away.
