Product Engineer

I join startups as the first product person and own the product function end-to-end:
strategy, execution, and growth.

My role in the product development lifecycle

I own the full product lifecycle: from discovery through engineering handoff, development management, launch, and growth.

  1. 01

    Discovery

    Problem, users, business context

  2. 02

    Requirements / Scope

    Use case, MVP, constraints

  3. 03

    Product Spec / PRD

    Flows, logic, edge cases

  4. 04

    Prototype / Validation

    Prototype, feedback, iteration

  5. 05

    Engineering Handoff

    Spec + prototype, build begins

  6. 06

    Development Management

    Backlog, sprint decisions, scope clarity

  7. 07

    Launch & Growth

    GTM, rollout, retention, growth loops

  8. 08

    Learn

    Metrics, signals, next solutions

Learn → back to Discovery

I applied this model at Optifeed to build their product development process from scratch.


About

I join early-stage teams as the first product person and own the product function end-to-end: direction, execution, and growth.

Most recently at Optifeed, where I built the product development process from scratch, ran discovery, and prototyped new features with Claude Code and Codex. My background spans early-stage AI and SaaS across e-commerce, procurement, fintech, edtech, logistics, and EV charging.
