  • Model data with SQLAlchemy on MySQL/Postgres; use ClickHouse and S3/Parquet.
  • Run services on AWS with Docker + Kubernetes (Helm/Kustomize, GitOps optional).

  • Add observability (logs/metrics/traces), CI/CD with GitHub Actions, safe rollouts.
  • Collaborate with teams on API contracts, performance, and security.
  • Integrate device intelligence and bot-mitigation with privacy controls.


Required

  • Python expert (3.12+ preferred): typing/mypy, async/multiprocessing, testing, profiling.
  • Proven REST API design and operations at scale.
  • Payments/fintech: disputes/chargebacks, reconciliation, integrations.
  • Orchestration/workflows and event-driven patterns; human-in-the-loop.
  • AWS, Docker, Kubernetes in production; GitHub Actions; observability.
  • Terraform in production (modules, remote state, policy as code).
  • Strong SQL; SQLAlchemy; columnar DBs (e.g., MySQL, ClickHouse).
  • Systems basics: networking/HTTP/TLS, concurrency, performance.
