01 Selected Work

Systems I've built and shipped.

Four systems that shipped and ran in production.

01

A proactive GTM engine, built end-to-end

The challenge

Pipeline was 100% inbound: auto-scored, one manual reply each. It worked, but it was the whole motion. The brief: build the next one.

What I built

An outbound engine that treats public developer activity as intent. It pulls every signal (stars, forks, installs, container pulls, telemetry, hiring), enriches each contact, and scores it on ICP fit plus signal strength.

  • Deduped daily against inbound, so no one gets double-touched.
  • A Python scoring module (stdlib only) makes every ranking auditable.
  • An LLM copy layer drafts each sequence, gated by deterministic rules before send.
  • A self-improving loop: every conversion re-weights the model and grades the copy that worked.

The outcome

Shipped as a live app plus a runnable scoring model. Every number came from a real public API. Runs on ~0.1 FTE once live.

02

Production multi-agent marketing system

The challenge

A 30+ person marketing team with zero agentic infrastructure. Everything ran on manual triggers.

What I built

A 24/7 system where orchestrator agents coordinate subagents in parallel. Content, data refresh, reporting, and knowledge upkeep all run without manual triggers.

  • Self-improving loops: weekly agents propose rule changes; monthly cycles auto-approve them only if benchmarks improve.
  • RAG memory over a ~1,000-doc vector-indexed wiki, with semantic search and automated pruning.
  • Decay-weighted scoring that keeps high-value knowledge within token limits.
  • Eval frameworks: skill-trigger accuracy, output quality, and retrieval precision, with regression tracking.

The outcome

24/7Autonomous operation, no triggers
~1,000Docs in vector-indexed memory
30+Person team served

03

Incrementality testing framework

The challenge

Spend ran on platform-reported conversions, numbers the platforms grade themselves on. No honest read on what was incremental.

What I built

A from-scratch incrementality framework in Python on the ads-platform APIs. Lift experiments that separate causal impact from correlation.

  • Set the experimentation culture behind today's agent-driven testing.
  • Wired results into budgeting, so spend followed proven lift.

The outcome

~15%CAC improvement

04

GTM data infrastructure & conversion tracking

The challenge

Marketing, product, data, and legal ran on inconsistent signals. In-platform and backend numbers disagreed, and the pipeline the agentic layer would need didn't exist.

What I built

The foundation the agentic layer runs on: end-to-end Segment CDP, server-side CAPI events, and lifecycle-stage conversion events, all GDPR-compliant.

  • Closed the gap between in-platform and backend data with automated reporting.
  • Coordinated marketing, product, data, and legal to keep pipelines clean.

The outcome

2M€+ARR uplift contribution
~7%Conversion-rate improvement
~10%More open pipeline generated
