About

I build the side you don't see: APIs, distributed services and the infrastructure that holds them up. I enjoy reasoning about latency, consistency and failure modes as much as writing the code itself.

I come from a software engineering background with strong roots in mathematics, which makes me comfortable with algorithms, analysis and low-level systems. I work on Linux (Arch) daily and use AI-assisted workflows to iterate faster without losing rigor.

Projects

Featured project

Distributed event-driven API

Code

A microservices platform whose services communicate asynchronously over an event bus. Go services handle high-throughput paths while Python services orchestrate business logic and processing. Designed to scale horizontally and tolerate partial failures.

  • Sustained ~1.2k req/s with p99 latency ≈ 54 ms under load
  • Kafka over SQS for replay and per-partition ordering; idempotent consumers with the outbox pattern
  • Service contracts via gRPC with versioned Protobuf schemas
  • Kubernetes deployment (3 replicas, rolling updates) and CI on GitHub Actions
  • Observability: structured logs, Prometheus metrics and OpenTelemetry tracing
  • Go
  • Python
  • Apache Kafka
  • PostgreSQL
  • Redis
  • Docker
  • Kubernetes
