About

I began my professional journey as a freelance frontend engineer, building frontend products with Next.js, TypeScript, and Tailwind while also creating smart contracts and working on Web3 projects. I later gained 1+ years of experience in a fast-paced product startup, shipping features quickly and solving complex problems. Currently, I also evaluate code generation quality of LLMs on real-world engineering tasks. I love coding, exploring new technologies, contributing to open source, and building ideas from scratch. I created ResumeGenie, an AI resume builder made at a time when “vibe coding” wasn't even a term, along with a full Web3 freelancing platform built end-to-end. Active open-source contributor to projects including Next.js, shadcn/ui, Cal.com, Dub.sh, and multiple repos with 20k+ GitHub stars.

Work Experience

Mercor / Alignerr

2025 - Present
Software Engineer (AI Model Evaluation)
Evaluated code generation quality of LLMs on real-world engineering tasks across bug fixes, feature work, refactors, and system design prompts in TypeScript, Python, Rust, and Solidity. Reviewed agent outputs for diff quality, tool usage, test coverage, and correctness across large open-source repos; delivered structured feedback for RLHF and ranking pipelines. Spotted hallucinations, unsafe code paths, and weak abstractions in model-generated solutions; flagged recurring failure patterns to improve prompt-response workflows. Benchmarked and compared outputs across multiple models to surface performance gaps and improve consistency on practical engineering tasks.
