Building with AI

As a PM who also ships, I use AI as a daily co-pilot - from spec to production. SmartJobTracker, Dashwheel, MarketTracker and SmartDocManager were all designed, coded and shipped solo using the stack below.

Claude Code
Anthropic · Agentic coding

My primary build agent - scaffolding, refactors, debugging and multi-file changes straight from the terminal. Built most of SmartJobTracker this way.

Cursor
AI code editor

In-editor AI pair programming for fast inline edits, tab completion and reasoning over the whole codebase.

Claude API
Claude Haiku · In-product AI

Powers SmartJobTracker's email parsing, STAR-story generator and adaptive CV rewriter - prompt design, structured outputs and cost-aware model selection.

Vercel
Deploy · Serverless

Hosting, serverless functions and CI previews. From git push to a live URL in minutes, with zero infra to manage.

GitHub
Version control · CI/CD

Source control, branching, PR workflows and Actions - the backbone connecting code to automated deploys.

Modern web stack
React · Vite · Tailwind · Node

Comfortable reading and shaping a modern JS/TS stack - enough to direct the AI, review its output and ship production code.

What colleagues say

Recommendations from managers, peers, and collaborators across my career.

"You can count on Alex to follow through and figure things out. Alex started as the first and only program manager in Japan for the ads product pillar. He worked across functional teams such as engineering, product, and sales to craft the initial product operations processes. Alex built up the various work streams and found ways to reduce overhead."
