What I Do

Engineering focus areas that guide how I design systems, ship features, and iterate in production.

01

Backend Systems

I build mostly using Typescript and Python(actively discovering new languages), focusing on accurate error handing, clear data ownership and clear API routes

02

Applied ML

I love fine-tuning and evaluating open-source models for practical use cases, and have a lot of fun with muti-agent experiments and prompt engineering.

03

Practical Product Delivery

Turning prototypes into actual usable products across web, mobile, and desktop with measurable user outcomes and feedbacks.

04

Light Weight Developer Tooling

I like making small but useful tools that improve my daily productivity, and I prefer simple scripts and local setups over complex platforms and cloud services for most use cases.
