壊れないものを作る。— I build things that don't break.
Computer Science student, backend-leaning, mostly living inside terminals and API docs.
- 🔧 flogging together RESTful APIs and microservices, mostly in Go
- 💳 specialise in payment systems — reconciliation, idempotency, ledgers that gotta be right every time
- 📦 messages go through Kafka/RabbitMQ before I trust 'em, no dramas
- 🔌 services yarn to each other over gRPC when REST is too slow
- 🗄️ data sits in PostgreSQL/MySQL, gets cached in Redis, gets searched in Elasticsearch
- 🧵 long-running jobs get handed to Temporal so nothing gets lost halfway
- 👀 keeping an eye on it all with Prometheus, Grafana and Jaeger — can't fix what you can't see, ay
- ☕ having a crack at Spring to see how the enterprise mob does it
- 🧪 if a service can't survive a restart, she's not done yet
Focus: payment and e-commerce APIs — auth, catalog, orders, transactions — the boring-but-critical stuff that's gotta stay up, no excuses.
PostgreSQL/MySQL for the source of truth, Redis/Valkey when speed matters more than durability, ClickHouse for the analytics side, MinIO for object storage, Kafka/RabbitMQ so services don't yarn to each other directly.
