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.

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%.

Manage a team of 3 engineers (1 Senior Frontend, 2 Full Stack) — conducting weekly 1:1s, leading bi-weekly frontend huddles to share best practices and drive community-owned code conventions, owning sprint task assignment, participating in performance review cycles, and contributing to compensation negotiations; additionally mentored an AI engineering intern through a separate weekly 1:1 cadence.

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.

Served as the primary frontend architecture decision-maker for the product engineering team, collaborating directly with the CEO, CTO, and exec-level product managers while bridging a distributed team across New York, San Francisco, and Seoul.

Independently designed and shipped developer-facing SDKs across 8+ languages and frameworks — JavaScript, Next.js (App and Pages Router), React, Python, FastAPI, Django, Flask, Rust, and Go — enabling external developers to integrate auth/authorization infrastructure across a wide range of tech stacks.

Oversaw and maintained customer-facing, security-critical pages administering user authentication flows implementing best practices in data protection and secure UI/UX across high-stakes surfaces.

Engineered and launched internal and external dashboard features end-to-end from scoping through deployment while exercising full autonomy and ownership typical of early-stage startup environments.

Supported engineering hiring by engaging in technical interviews, influencing team culture and candidate assessment criteria at company spearheaded by YC-backed founder.

Leveraged technical expertise to ideate and architect highly successful Proof of Concept (P.O.C.) applications, driving revenue generation of $1M+ and establishing the company as an industry leader in delivering innovative and customized solutions within aggressive timeframes.

Directed and coordinated the full lifecycle of projects in collaboration with Product and Engineering teams. Orchestrated concise planning, execution, and delivery of new services through daily meetings, strategic milestone setting, and rigorous code reviews,

Effectively managed deliverables across 40+ short-term sprints, ensuring adherence to deadlines through agile development processes, daily team meetings, and streamlined communication between team members and Product managers.

Recognized for exceptional performance and promoted twice within a span of 2 years, transitioning from a Junior developer to a Senior developer. Embraced increased responsibility and contributed to the design and implementation of more intricate projects.

Conducted over 10 technical interviews to evaluate and assess candidates for Full Stack developer positions across multiple engineering teams
