Need a reliable backend — or want to add AI/LLM features to your
product? You're in the right place.
I'm a Backend Developer with 9+ years of experience building scalable
web applications, REST APIs, and automation systems using Python,
Django, and FastAPI. Over the last few years, I've specialized in
integrating Generative AI and LLMs into real products — not demos,
but production-ready features your users can actually rely on.
Here's how I can help you:
🔹 Backend & API Development — Robust REST APIs and backend services
with Django & FastAPI, built to scale.
🔹 AI & LLM Integration — GPT/LLM-powered features like text
generation, chatbots, and intelligent automation using LLM APIs,
RAG, and tools like n8n.
🔹 Automation & Web Scraping — Custom Python scripts that automate
repetitive workflows and save you hours.
🔹 Database Design — Optimized PostgreSQL & MySQL structures for
fast, reliable data handling.
🔹 Cloud Deployment — Deploying and maintaining applications on AWS.
A bit about my background: I currently work as an Associate Consultant
Developer at GlobalLogic, building Python automation and AI-powered
backend workflows. I've also led development teams and delivered
healthcare, e-commerce, and SaaS applications for clients across
multiple industries.
What you can expect working with me:
✅ Clean, well-tested, maintainable code (Pytest, debugging, tuning)
✅ Clear communication and regular updates
✅ Deadlines I actually meet
If you want a developer who understands both solid backend engineering
AND modern AI, let's talk. Send me your project details and I'll reply
with exactly how I'd approach it.

Cut ~70% of a client's manual support work with an AI agent. I build AI agents, voice AI, RAG and n8n automation on Python/FastAPI. 7 years backend, 3 on LLMs, 15+ systems in production.
Shipped recently
→ AI support agent — 70% less manual ticket handling
→ Voice intake agent — takes the call, qualifies, writes to CRM
→ Document Q&A — answers pulled from PDFs, with citations
→ Instagram automation — content delivered, no one touching it
