Summary

Fullstack engineer with a backend focus and 8+ years across Go, TypeScript, and React. Comfortable owning services end-to-end.

Software Engineer | Customer Analytics Dashboard Jan 2024 – Present

Joined as the second engineer on a 3-person team building a customer-facing B2B analytics platform. Fullstack contributor since early development, primarily Go APIs (~70%) and Vue 3 UI (~30%).
Built ClickHouse summary tables (hourly/daily AggregatingMergeTree materialized views) so reports read from compact rollups instead of raw events.
Ship customer-requested features end-to-end weekly, from PostgreSQL schema and Go API through to Vue 3 UI.

Software Engineer | Moodboard Jan 2023 – Nov 2023

One of 2 engineers maintaining Moodboard, a paper.js-based canvas tool for designers (shapes, arrows, images from user galleries, color swatches; rotation, resize, layering).
Implemented the side-panel toolbar UI per product/design spec.
Refactored portions of the codebase to address accumulated bugs after taking over maintenance.

Tech Stack: JavaScript, TypeScript, React, paper.js, Node.js, MySQL, Docker

Software Engineer | Website Services Sep 2021 – Dec 2022

Engineer on a 4–5 person team building a website-builder product for small contractors and designers: a React drag-and-drop WYSIWYG editor backed by a Java Spring API that persists each site as a component tree, with a separate Next.js service rendering published sites from the same components.
Built the blog feature end-to-end on joining: data model, Java Spring APIs, React editor surface, and /blog/* routes on the published-site renderer.
Built the media upload pipeline for user-uploaded assets: direct-to-S3 uploads with Lambda-based virus scanning before assets became publicly accessible.
Contributed to extracting the app from the Houzz monolith into a manifest-loaded micro-frontend: standalone local dev server, lightweight backend, and a deployment pipeline that exposes the bundled app via a runtime manifest.

Tech Stack: Java, TypeScript, React, Next.js, Node.js, MySQL, AWS S3, AWS Lambda, Docker

Software Engineer | Campaign System Sep 2017 – Aug 2021

Started as a frontend engineer (React/Redux campaign and leaderboard UI); moved to backend Go after ~2 years.
Built leaderboard features for live-stream campaigns: auth, voting, scheduling, reward distribution.
Built load-testing tools for campaign rollouts. Contributed to a campaign-content WYSIWYG editor (lead-designed).
