ABOUT ME

I'm an experienced Software Engineer focused on building high-impact products for a global user base. I thrive at the intersection of thoughtful design and robust engineering — where beautiful UI meets resilient, scalable systems.

Currently, I'm a Senior Frontend Engineer at Layers AI, where I designed and shipped App Machina end-to-end — positioning it as the first Mobile Measurement Agent (MMA). I built the marketing site and a seven-surface authenticated dashboard with React 19, TanStack Router, Tailwind v4, Shadcn UI, and Framer Motion, and partnered with the design lead on a UI modernization of Layers, the company's flagship UGC marketing platform.

Previously at EStation, I built a terminal-grade POS with real-time sync and offline-first state, and architected a multi-tenant e-commerce engine plus a JSON-driven headless CMS. Before that, I led frontend at Neue World on Flozi (Notion-to-Webflow sync) and Layers (blockchain-integrated freelance platform). I've worked across startups, remote studios, and agencies — always focused on shipping software that matters.

When I'm not shipping features, you'll find me refining components, sketching UX flows in Figma, or figuring out how to teach LLMs to think like engineers.

EXPERIENCE

01

01 Layers AI Inc

Designing and shipping App Machina end-to-end, positioning it as the first Mobile Measurement Agent (MMA) — distinct from legacy mobile measurement platforms.

Senior Frontend EngineerApril 2026 - Present

Key Achievement 1

Built the full marketing site and a seven-surface authenticated dashboard — attribution funnels, campaigns workbench, audience cohorts — using React 19, TanStack Router, Tailwind v4, Shadcn UI, and Framer Motion.

Clean is a component lab. Notes is a small writing space. Loupe and TextFlow, just below, are the bigger builds. Everything here is what I do when no one's paying me to — the things that keep my taste sharp between paid work.

Loupe

ASO Audit Agent

02

Agent-Led Audit

A Mastra AI agent applies an App Store Optimization methodology skill to score every dimension and write the recommendations.

Guardrails First

A deterministic TypeScript engine measures the facts, clamps the agent's scores, recomputes the weighted total, and serves as a full fallback.

Skill-as-Methodology

The 10-dimension ASO rubric lives as a Mastra workspace skill the agent consumes — editable by non-engineers, not buried in code.

Idiomatic Mastra

Tools own external IO, the workflow orchestrates four steps, the agent + skill do the judgment, Zod re-validates the shape.

Agent + Skill

Mastra agent uses the ASO methodology skill as its system prompt — it scores and recommends, not just refines.

Deterministic Guardrail

Clamps scores to 0–10, recomputes the weighted /100 in code, Zod-validates, and falls back gracefully.

Two-Pass Refinement

Parallel scoring + recommendation passes; deterministic before/after survive any agent omission.

TextFlow

Architected completely from the ground up. No boilerplate, just thoughtful engineering from day one.
