Event-driven workflow engine on directed acyclic graphs (DAGs).
- The Stack: Python, FastAPI, PostgreSQL, asyncio, React, TypeScript, React Flow.
- The Solution: Async parallel DAG execution, JSONPath expressions for dynamic payloads, and Time-Travel Debugging via event-sourcing (replay the historical state of any run, node by node).
- Extras: Visual graph editor built with React Flow.
Multi-store ecommerce builder, SaaS-style (à la Shopify / Tienda Nube).
- The Stack: Go, MongoDB, Redis, SvelteKit, TypeScript, Docker, microservices.
- The Solution: Never oversell stock under concurrent load, isolated per store — atomic MongoDB operations and time-boxed cart holds with Redis, in a multi-tenant Go microservices architecture.
- Extras: SvelteKit frontend covering marketing, storefront per store, and merchant dashboard.
REST API for membership management at a health/sports club.
- The Stack: Java 21, Spring Boot 3.3, MySQL 8, Flyway, MapStruct, Resilience4j, Bucket4j, Docker, GitHub Actions.
- The Solution: On-demand membership state engine (no caching). Real concurrency control: an initial @Transactional + SELECT FOR UPDATE attempt failed under load (commit happens after method return) — fixed with a per-client JVM lock + TransactionTemplate, verified with a 10-parallel-request test against a quota of 1.
- Extras: 27 tests (H2 for unit/controller, Testcontainers for integration), retry + circuit breaker on outgoing webhooks, rate limiting, and plan-catalog caching. Deployed to production via Dokku with CI/CD.
Chaos Engineering playground with real OTP processes, not simulations.
- The Stack: Elixir, Phoenix LiveView, PostgreSQL, Tailwind, Docker.
- The Solution: Every infrastructure node on the canvas (load balancer, API, DB, cache, queue) is a real GenServer under a DynamicSupervisor — "killing" a node runs an actual
Process.exit(pid, :kill). Deliberate:temporaryrestart strategy to show real "let it crash" behavior, no auto-heal masking the failure. - Extras: Live metrics dashboard (RPS, p99, error rate), automatic Chaos Monkey, and a centralized traffic simulator generating concurrent load. 101 tests running in CI/CD on every push to main.
