• Designed and maintained REST / WebSocket APIs in FastAPI and Flask, enforcing JSON-schema validation with Pydantic and rate-limiting middleware. • Authored Erlang/OTP services (gen_server, supervision trees, ETS-backed caches) for high-throughput order routing and event streaming. • Modeled relational data with SQLAlchemy; managed migrations via Alembic and optimized complex queries with Postgres EXPLAIN / ANALYZE. • Implemented message queues and pub-sub pipelines (RabbitMQ, Redis Streams, Kafka) to decouple on-chain/off-chain processing and guarantee exactly-once delivery. • Owned CI/CD pipelines: GitLab CI → Docker build → Helm chart release → ArgoCD sync to Kubernetes (multi-region staging & prod). • Instrumented telemetry and alerting using Prometheus, Grafana, Loki, and Sentry; wrote custom exporters for smart-contract events. • Performed load-testing and profiling (Locust, py-spy, wrk) to locate bottlenecks and guide CPU/memory tuning at both Python and BEAM VM levels. • Maintained IaC configuration with Terraform and Helmfiles, automating service roll-outs and secret rotation across AWS / GCP clusters.
