Mikhail Kugan

Software engineer · Berlin · 42 Berlin Common Core

Python TypeScript C Go Elixir Dart Docker Linux

I build backend tools with the reliability semantics baked in – webhook routing with at-least-once delivery, click-fraud detection encoding a decade of ad-network operations. Before software engineering I spent 11+ years in performance marketing running the systems engineers build for: postbacks, S2S integrations, tracking pixels, attribution windows, anti-fraud rules. Now I'm rebuilding from the systems layer up at 42 Berlin.

Open to backend, platform, integrations, full-stack and mobile roles in Berlin or remote within the EU.

Projects

Repo What it is Stack
webhook-hub Self-hosted webhook router – HMAC verification, dedup, Postgres persistence, at-least-once fan-out with retries, dead-letter queue and replay Python · FastAPI · Redis
clickguard Click-fraud and bot-traffic detection for access logs – pluggable detectors, intensity-scored banding (clear / suspect / fraud) Elixir
42_minishell Unix shell – tokeniser, parser, AST-based execution, pipes, redirects, heredocs, signals C
42_philosophers Dining philosophers – threads & mutexes, plus a processes & semaphores bonus C
42_inception Multi-service infrastructure from scratch – NGINX, WordPress over HTTPS, MariaDB, Redis, each in a custom Alpine container Docker
weather Mobile weather app – city search, geolocation, hourly and weekly forecasts, charted temperature curves Flutter · Dart

Now

  • 42 Berlin Common Core – the C/systems track is behind me (shell, ray tracer, HTTP server in C++, Docker infra all passed); building outward from there
  • Finishing webhook-hub's documentation and test coverage
  • Pushing German from certified B2 toward fluency

Background

11+ years in CPA and PPC affiliate networks (2009–2020): owned tracking infrastructure, third-party integrations, and operational tooling. Attribution, conversion funnels, fraud detection and compliance – in production, not just in the spec.
