I build software that has to be right.

Enterprise SaaS backend systems, REST APIs, and AI features — engineered to stay fast, correct, and unremarkable under real load.

All work

Work, launched like a product.

Not a gallery of mockups. Each project shipped to production, moved a metric that mattered, and paid down long-term quality.

Why hire me

What I bring to a team.

01

Problem solving

I start from the data model, not the library. When a query is slow I read the query plan before touching the code.

02

Ownership

Production issues are feature requests. I read the logs first, then refactor so the next engineer doesn't trip.

03

Product thinking

The metric, not the ticket, is the requirement. A feature that ships on time and stays reliable wins.

04

AI engineering

LLMs are only useful grounded and evaluated. Retrieval, not prompts, is where the quality lives.

05

Backend craft

Clean schemas and fast queries beat clever code. The best backend is the one nobody has to think about.

06

Performance

I profile against real load before calling it done — query plans, latency, and the p95, not the happy path.

Build philosophy

How I approach software.

01

Architecture first

Schema and contracts before code. Interfaces are the product — everything else is implementation detail.

02

Quality is a habit

Tests, reviews, and refactors are the norm, not the exception. The code you inherit is code you improve.

03

Ship, then measure

Perfect is the enemy of shipped. Get it to production, watch the metrics, and iterate on reality.

AI journey

From exploration to automation.

01

Exploration

B.Tech in AI & ML — learned models are easy and production is hard.

02

RAG

Grounded LLMs on real company knowledge, not a demo corpus.

03

LLMs

Prompt engineering, evaluation, and shipping AI features to enterprise customers.

04

AI tools

Agentic helpers for my own workflow — to see what actually holds.

05

Automation

Production ML applications that quietly do a job end-to-end.

Thought process

From problem to measured outcome.
