What I do

LLM & AI Integration

I integrate LLMs (OpenAI, Anthropic, local models) into your existing product or build AI-native features from scratch — RAG pipelines, agents, and workflow automation.

OpenAI API LangChain RAG Vector DBs

MVP Development

Fast, clean, production-ready MVP delivery. I take an idea and turn it into a working, deployable product — backend, APIs, database, and deployment all in one engagement.

Python FastAPI PostgreSQL Docker

Backend Architecture

Scalable, maintainable backend systems — REST APIs, database schema design, async processing, and system architecture designed to grow with your product.

Backend Rescue & Refactoring

Got a fragile legacy codebase slowing you down? I audit, restructure, and improve existing backends — improving performance, reliability, and developer velocity.

Code Audit Refactoring Performance Testing

Internal Tools & Business Systems

Custom internal platforms, admin dashboards, ETL pipelines, and business automation — built for your exact workflow, not adapted from a generic template.

ETL Pipelines Automation Dashboards Integrations

Technical Consulting

Architecture reviews, tech stack decisions, and engineering strategy for teams who need senior-level thinking without a full-time hire.

How I work

My process

Discovery call

We talk about your project, requirements, timeline, and goals. No sales pitch — just honest engineering conversation.

Architecture proposal

I map out a clear technical approach — stack choices, data models, system boundaries — before writing a single line of code.

Build & iterate

Focused delivery in tight cycles. You see real progress weekly, not a black box that opens 3 months later.

Handover & support

Clean docs, deployment ready, code you can actually maintain. I don't disappear after delivery.
