Frontend Engineer. building AI-integrated products that ship.

A decade of turning ambiguity into shipped software. Deep frontend craft, working backend fluency, and hands-on AI engineering — RAG, tool calling, guardrails — proven across 10+ products I've built and shipped solo.

AI Governance

Magpie

Scanner that finds AI systems missing from a company’s compliance register by reading source code. Publishes its own measured recall (66% on held-out code) rather than claiming completeness.

AI SaaS

CompetePulse

Slack-native competitive change agent — crawl/diff pipeline with a materiality classifier and eval harness, HITL battlecards, and billing. pnpm monorepo on Cloudflare Workers.

Chrome Extension

DeepWork Tab

Your editor has a focus mode; your browser doesn’t. A hard tab cap, a calm intercept screen, and a queue that makes closing a tab feel safe.

Backend · AWS

Hashtag Pipeline

SecretScrub

Turns logs, configs, and incident bundles into reviewed safe copies before you paste them into an AI tool. Detects secrets, swaps in consistent semantic placeholders, preserves structure — all on-device, originals never uploaded.

macOS App

FolderMind

Native SwiftUI file organizer for macOS — a visual rule builder that sorts folders automatically, with onboarding tuned to get you to your first sorted file in under 90 seconds. Notarized DMG with Sparkle auto-updates.

macOS App

CaffeineBar

A macOS menu bar app that logs each coffee in one click and plays increasingly unhinged sounds as your intake climbs — gentle concern at cup 3, a full ambulance by cup 5. Funny enough to share, useful enough to keep.

Experience

Where I've
shipped.

2021 — Present

Independent

Product Engineer — Developer Tools & AI

In 2021 I left consulting to build products end-to-end — I wanted to own every decision from architecture to launch, not one slice of a delivery pipeline. Since then I've designed, built, and shipped 10+ products solo: git-scope (100+ GitHub stars, Homebrew distribution), npm libraries (ai-cost-guard, loopkit, debugg), and production SaaS like RivalEye — auth, billing, background jobs, and AI pipelines included. Five years of shipping alone taught me velocity, ruthless scope-cutting, and daily hands-on AI engineering: agents, RAG, guardrails. Now I'm looking to bring that end-to-end speed to a team building something bigger than one person can.

2019 — 2021

Accenture

Full-Stack Engineer

Built an enterprise Code Scan Platform from scratch that identified vulnerabilities in large-scale applications. Reduced deployment time by 60% with CI/CD pipelines and delivered pixel-perfect React dashboards from Figma designs.

2015 — 2019

Infosys

Full-Stack Engineer

Delivered secure banking features for national banks. Improved backend performance by 40% with Redis caching and PostgreSQL query optimization. Converted Figma wireframes into production-grade UIs in Agile sprints.
