Designed the backend for a production telecom learning platform: multi-tenant organization membership, course commerce, protected-content entitlements, quizzes, certificates, and dual-currency Stripe payments. Built an on-demand lab control plane that provisions isolated AWS EC2 and Free5GC environments, meters usage by minute, and reclaims idle capacity.

Built the application backend for collaborative workspaces, role-aware membership, invitations, boards, lists, and ranked tasks. Type-safe tRPC APIs sit over a relational Prisma and Neon Postgres model, with session and passkey authentication plus Redis-backed coordination.

Backend
Oct 2024 – Present()

Engineered an event-driven delivery backend around explicit state ownership and durable execution. PostgreSQL records authoritative booking transitions; a transactional outbox and Kafka publish committed facts; Temporal coordinates driver matching and timeouts; Redis handles geo-discovery and expiring reservations without becoming the source of truth.
