Five years, 30+ projects, and one rule that hasn't changed: I won't build something I know will break under real growth. That's saved clients from expensive rebuilds more times than I can count, and it's why most of them come back. The core of what I do is SaaS. Multi-tenant architecture, Stripe subscription billing, role-based access controls, admin dashboards built to scale from your first user to your first ten thousand without touching the foundation again. I've shipped platforms that handle real traffic, real payments, and real users, not just demos that look good in a Loom video. Beyond SaaS, I build web applications on Next.js and React that are fast, SEO-ready, and built to convert. E-commerce stores with checkout flows that reduce cart drop-off. REST APIs and backends with Django, FastAPI, and Node.js that are documented well enough that any developer can pick them up without calling me. In 2025 and into 2026 I've been building AI-powered features into SaaS products, integrating large language model APIs, building prompt pipelines, and connecting AI capabilities into products that actually needed them, not just as a marketing checkbox. Before any code gets written, scope, timeline, and cost are locked in. You get regular updates throughout. If something in your plan is going to hurt you long-term, I'll tell you before I bill you for it. When delivery happens, I stay until it works. If you're building something and want a straight answer on whether your approach makes sense, send me a message. I'll respond within a few hours with honest feedback, not a pitch.

I build Python backends and the AI features that run on them. Most of the AI work I get pulled in to fix has the same story: it was built as a demo, and it broke the first time it met production traffic, live data, or a real bill. I work the other way around — backend first, then the AI wired in properly. Backend and APIs This is the core of what I do. REST APIs in Django and FastAPI, built to handle production traffic rather than just pass a quick test. Auth with JWT and OAuth, payments through Stripe and Razorpay, PostgreSQL and MongoDB schema design and indexing, and background jobs on Celery and Redis. With third-party integrations, I handle the part most people skip: what the system does when the external service is slow, down, or returning errors. GenAI integration On the deeper end, I build agentic systems in LangChain and LangGraph: custom tools, multiple agents working together, and proper memory and context handling across a workflow, with tool calls connected to the actual backend. On the everyday end, that's chatbots, content generation, automation, and retrieval over a client's own data (RAG) where it fits. I work across OpenAI, Claude, and Gemini, and I trace LLM calls and track token spend, because in production the cost matters as much as the output. What I care about is that the AI sits on a solid system — auth, a database, error handling, retries — so it behaves like a feature, not a science project. Deployment I deploy what I build. Docker, AWS or DigitalOcean, so the work goes out live and running, not handed over as a folder of code someone else has to figure out. How I work I ask questions before I write anything, because the wrong assumption early gets expensive later. I deal with edge cases instead of hoping they won't show up. I keep the code clean enough for the next person to read, I reply quickly, and I hit the dates I commit to. Industries I've worked in: e-commerce, SaaS, education, logistics, and internal tools. If you need a backend you can rely on — a new build, a broken system that needs sorting, or AI features that have to hold up in production — send me the details and I'll tell you how I'd approach it.

⭐ Top Rated Plus | 100% Job Success | 40+ five-star projects | $70K+ earned Your backend shouldn't crumble at 10,000 users. Your LLM features shouldn't hallucinate in production. And your MVP shouldn't need a rewrite six months in. I'm a Senior Python + AI Engineer with 7+ years building SaaS products, production APIs, and multi-agent AI systems that hold up under real users. Clients hire me when the AI hype meets reality — and they need someone who ships working systems, not demos. ⭐ WHAT RECENT CLIENTS HAVE SAID 💬 "One of the best technical decisions we've made this year. The OCR automation system he built for our law firm has fundamentally changed how we handle documents." — Law firm, PDF Form Automation 💬 "Top-tier developer.

He is the best." — Django + PostgreSQL Engagement 🤖 AI & LLM SYSTEMS (My Specialty) - Multi-agent systems with LangGraph, LangChain, MCP - RAG pipelines with vector databases (Pinecone, pgvector, Chroma) - OCR + LLM document automation at 98–99% accuracy - LLM-based monitoring, anomaly detection & evaluation systems - OpenAI, Anthropic Claude, and open-source model integration 🐍 BACKEND ENGINEERING - Django / Django REST Framework / FastAPI - Scalable REST APIs, SaaS backends, authentication, billing - PostgreSQL, Redis, Celery, async workflows - Scaled production systems from MVP to 100K+ users ⚛️ FULL-STACK (When Needed) - React / Next.js with real-time features - Tiered billing, dashboards, auth flows, admin panels - End-to-end delivery paired tightly with the backend 🔧 DATA & DEVOPS - Web scraping & ETL pipelines - Docker, AWS (EC2, Lambda, S3, RDS), CI/CD - Production-grade monitoring and deployment 🎯 I'M THE RIGHT FIT IF YOU NEED: ✅ A LangGraph or multi-agent system that works beyond the demo ✅ A RAG or LLM pipeline that's accurate, observable, and scalable ✅ A Django or FastAPI backend built for real growth ✅ A senior engineer who communicates clearly and hits deadlines (40 consecutive 5-star reviews) ❌ Not a fit if you want the cheapest developer, or "vibe coding" with no thought to architecture or scale. Send me a message describing what you're building and the problem you're solving. I'll reply within 2 hours with honest feedback on scope, approach, and whether I'm the right person for it.

I have experience of working with nearly everything inside and outside of programming domain. All of my external ventures have had the pleasant effect of allowing me to make connections where most people don't even think to look, and make use of all of my skills to the best of my abilities. I absolutely love thinking outside of the box, and most of my personal projects are just a touch crazy in general; I call them creative. Tech buzzwords: - Python (2, 3x), FastAPI, Flask, Celery, asyncio, Django, multithreading/multiprocessing, pytest, unittest; - Databases: PostgreSQL, MongoDB, Redis, ORMs (SQLAlchemy/Alembic, Django ORM - Web: WebSockets, gunicorn, Nginx, a bit of JavaScript/CoffeeScript/Angular, HTML/CSS; - DevOps: Terraforms, Kubernetes, Docker/docker-compose, Linux, deployed things to AWS, DigitalOcean and Heroku; - Machine learning related: Pandas, NumPy, did an API around a TensorFlow model. - AI/ML, NLP, RAG, LLM, LSTM, AGI, RNN, Transformers Usually, I develop individual Python script for each scraping task, so I can adapt my program to any website and deliver output data in different formats(CSV, XLS, JSON, text, database). My scripts can extract data from websites with JavaScript/AJAX, use proxies, solve captchas via 3rd party services, use multi-threading. I have proficiency to setup scripts on Digital-ocean or AWS server. Freelancing is my main source of income, so I pay a lot of attention to my clients, available to respond throughout the day and work full days to complete the projects as fast as possible. I tend to be extremely straight forward about what I can do and how long it might take me to do it. I know my limits, and I try to break past them every single day. Definitely won't be disappointed if given a chance to work together.
