Work History

Senior Full Stack Engineer / Engineering Manager

Chartmetric

10.2024 - Current

Promoted to Senior Full Stack Engineer and Engineering Manager within 8 months of joining, taking on technical leadership and people management responsibilities across a product engineering team at a bootstrapped music data and analytics company with $10M+ ARR.
Architected and led the creation of a company-wide Design System from the ground up — porting a designer's Figma library into a published NPM package with full Storybook documentation — eliminating UI inconsistency across 25+ pages, accelerating developer velocity, and becoming the daily foundation for all frontend engineers and AI coding tools.
Co-led an AI-first engineering initiative alongside 2 senior engineers and the VP of Product, embedding Claude Code and Devin into the product development workflow — enabling non-engineers to contribute code PRs and bringing AI-generated code to ≥90% of output.
Delivered 4 net-new music industry data domains end-to-end — designing performant backend queries against newly ingested data tables and building high-traffic, data-dense frontend experiences using the Design System, serving a large and active customer base.
Personally introduced ESLint and TypeScript correctness to the frontend codebase — a foundational improvement that had no prior standardization — driving adoption collaboratively with the broader FE team and establishing conventions that all engineers now follow.
Led and oversaw a frontend modernization project as FE team lead — directing an engineer through regular prioritization meetings to overhaul package imports across a 10-year-old codebase — reducing local startup time by 75% (from ~90s to ~30s) and cutting bundle size by over 50%.
Supervised a team of 3 engineers, including a senior frontend developer and two full stack developers. Conducted weekly individual meetings to support professional growth. Spearheaded bi-weekly frontend huddles to promote coding best practices. Managed sprint task assignments, ensuring alignment with project goals. Contributed to performance review processes and compensation negotiations. Mentored an AI engineering intern through consistent weekly meetings.
Acted as lead frontend architecture decision-maker for product engineering team, partnering closely with CEO, CTO, and executive-level product managers while connecting a distributed team across New York, San Francisco, and Korea.
