Manenimabasi Udoh | Senior Backend Engineer

I build backend systems in Go and TypeScript, with a focus on payments, wallets, and reliable distributed workflows. At Infostrategy Technology, I lead hands-on backend delivery across healthcare, commerce, and enterprise ERP systems.

My software development journey began in August 2017 with independent projects and freelance work. My current work combines service design, implementation, cross-service integration, code review, and mentoring.

What I Build

  • Payments and Wallets: Go/PostgreSQL services, precise balances, row-level locking, immutable ledgers, idempotency, and provider integrations
  • Distributed Workflows: gRPC APIs, Kafka events, transactional outbox/inbox patterns, retries, and asynchronous processing
  • Backend Platforms: authentication, RBAC, multi-tenant services, healthcare, commerce, and enterprise ERP workflows
  • Cloud and Delivery: AWS, Docker, CI/CD, and Kubernetes competency backed by CKA
  • Applied AI: backend services that integrate LLMs into engineering and product workflows
