Tefo CBS

A Blockly-based accounting-schema generator (350% efficiency gain for bank accountants) and an end-to-end Cypress suite (~620% faster QA cycles).

Lead the frontend chapter on Tefo, a high-availability Core Banking System for Afriland First Bank South Sudan (100,000+ clients, 24/7 SLA) integrating 19 banking microservices across accounting, transactions, KYC/AML, audit, parties, products and till operations. Designed and built @tefo/mr-review, an in-house RAG code-review agent on the Anthropic API that pulls per-MR context from Jira, Confluence, GitLab and live Swagger contracts and posts inline review comments back to the MR. Architected the frontend monorepo (Turborepo + Yarn workspaces) — two Next.js apps and ten shared TypeScript packages — under a strict domain-driven structure. Mentor junior engineers and run architecture and code reviews.
