React 19TanStack QueryNestJSChrome MV3

An Instagram cold-outreach desk that learns what gets replies.

The web app is the brain — products, message variants, audiences, campaigns, reply-rate analytics; a Chrome MV3 extension is the hands, sending DMs at human tempo inside the user's own session. A safety-first send engine: randomized typing, warmup ramps, daily caps, working-hours windows, dedupe and auto-stop on action-blocks.

What I built
  • Human-tempo send engine + safety rails
  • Chrome MV3 extension (DOM sending)
  • A/B message & language variant testing
  • Reply-rate analytics & inbox

05 — About

The short version.

I’m a software engineer who cares about speed, data and distribution — and how they combine into products people actually use.

My background is deep backend engineering: a decade building distributed, event-driven systems on Kafka, Cassandra and microservices — including exactly-once delivery pipelines and telecom-scale messaging platforms.

Today I put that foundation to work across the full stack — designing product architecture, blockchain integrations, real-time trading UX and mobile apps. I like problems where automation and on-chain data create a measurable edge, and I ship end to end: engineering, App Store / Play operations, and growth.
