What Iactually do

Three things, no filler
Ownership

Own it end-to-end

Ambiguous business requirement → technical spec → production deploy → post-launch monitoring. No handoff gaps, no waiting to be told.

Architecture

Build for scale

Multi-tenancy, RBAC, relational schema design, Redis and Cloudflare caching, Laravel queues, zero-downtime releases on AWS.

AI-native

Ship with AI in the loop

LLM APIs shipped inside client products, and AI coding tools in the daily workflow — faster output without dropping review standards.

WorkingAI-native

AI is in the loop every day, but it does not make the calls that matter. The split is deliberate.

  • AI draftsFirst-pass specs, scaffolding, test stubs, refactor sweeps, unfamiliar-API exploration.
  • I decideArchitecture, schema design, tenancy boundaries, and what ships to production.
  • ResultMore surface covered per sprint with review standards intact — bug reports still went down 30%.
