Built idempotent, signature-verified payment webhook pipelines with exactly-once guarantees across multi-currency settlement, achieving zero duplicate transactions in production since launch. Owns production backend and cloud infrastructure (GCP/AWS) for cross-currency payments, including containerised async Python services, Redis, task queues, and CI/CD at dev/staging/production parity.

Owned Kubernetes and CI/CD (GitHub Actions) at full environment parity, replacing VPN access with zero-trust networking (Tailscale, mTLS). Maintained Kafka event-streaming infrastructure with ordered, exactly-once delivery, and built a discrete-event fleet and demand simulator in C#/.NET to measure revenue and rider-earnings impact before rollout.

Designed multi-step async pipelines across third-party APIs with validation, dead-letter handling, idempotency, and retries, cutting silent failures to near zero. Shipped cross-platform systems software in Rust end to end.

Managed concurrent booking state under production load in NestJS/TypeScript, and PostgreSQL schemas with live, zero-downtime migrations using advisory locks.

As the first engineer, built backend architecture from zero to production, plus CI/CD, deployment runbooks, and the team's first incident-response playbook.

Developed numerical algorithms and computational models (Python, MATLAB) on HPC simulation pipelines, validating outputs against known analytical solutions rather than previous runs.

B.Sc. in Systems Engineering with a specialisation in AI & Mechatronics. Thesis on IoT-based fault detection for industrial distribution transformers, deriving a health index from live sensor telemetry.
