About

I work full-time as a software engineer while building personal products on the side —
as a way to keep up with new tech and learn by shipping.
With AI as a partner, I work end to end from design through operations.

Profile

I lean on AI for speed while keeping human judgment and quality bars at the core.
iOS apps, web services, and LLM-powered tools — from concept to operations.
Start small, validate, and keep refining what proves valuable.

Workflow

Working alongside AI

AI is involved across the full lifecycle, with humans owning judgment and quality.

Ideation
Surface problems and explore directions with AI.
Design
Shape requirements, architecture, and task breakdowns through dialogue.
Build
Generate and refactor code with AI for efficient delivery.
Evaluate
Use AI to support test design, reviews, and metric analysis.
Operate
Use AI to assist monitoring and improvement loops.
AI is a powerful partner, but human judgment and final responsibility always stay with people — that's how we ship trustworthy quality.

Domains

Three domains I work across — designing, building, and operating products.

iOS

Designing and shipping iOS apps with SwiftUI / Combine / SwiftData

Web

Building web services and dashboards with Next.js / TypeScript / NoSQL

LLM

LLM-powered products and prompt design

Principles

  • Move fast with AI; turn it into value through human judgment
  • Take responsibility through operations, not just the release
  • No hype — be clear about what's possible and what isn't
  • Separate decisions that can be automated from ones that need a human
  • Build small, refine through real use
  • Take user problems seriously
  • Stay transparent and improve continuously
