About
I'm Fredrick — based in Abuja, Nigeria. I design server-side architectures, REST APIs, database optimization, and auth systems. Core stack: Node.js, Express, NestJS, MongoDB, PostgreSQL, and FastAPI, with React when frontend integration is needed. Experienced leading engineering teams through delivery.
Skills
Experience
Architected two interoperating services: a NestJS/MongoDB product API and a Django/PostgreSQL scoring engine connected with RS256-signed service JWTs. Designed the core data model and built psychometric scoring, RBAC, S3-compatible uploads, Swagger documentation, and structured logging.
Led sprint planning, task allocation, and code review while architecting Stakeholders Connect. Built REST APIs, Socket.io chat and notifications, JWT/RBAC, optimized MongoDB schemas and queries, and owned AWS CI/CD with Joi validation and error handling.
Built pipelines that ingest, harmonize, and validate ESG scores, financial statements, and sustainability metrics across countries. Implemented real-time analysis on scalable data architecture with security and governance controls.
Built scalable Node.js, Express, and PostgreSQL services for Evolution and Officing. Designed relational schemas and complex SQL queries, wrote unit and integration tests, maintained technical documentation, and shipped features with product and frontend teams.
Built the backend server for a screen-recording Chrome extension with efficient real-time data handling. Contributed to authentication and payment microservices for a large e-commerce platform.
Education
Coursework in Algorithms & Data Structures, Database Systems, and Software Engineering.
Approach
Retries, timeouts, and clear ownership when a dependency drops.
APIs and events that other services can depend on without guesswork.
Logs, metrics, and query plans beat intuition when latency slips.
