Sandra Oyarekhua — Fullstack & Mobile Engineer
Based in Lagos, Nigeria. I architect products from database design to
production deployment and real-time observability — orchestrating
microservices, engineering high-concurrency APIs, and delivering
cross-platform mobile apps with React Native, Next.js, FastAPI,
Docker, and PostgreSQL.
Currently working on core infrastructure and microservices:
provisioning Docker environments, integrating Grafana, Prometheus,
Kafka, and Redis for real-time monitoring and event streaming, and
deploying an Open5GS virtual 5G core network for realistic network
behavior testing.
Skills: React Native, Expo, Next.js, React, TypeScript, FastAPI,
Flask, PHP, PostgreSQL, Supabase, Docker, Kafka, Redis, Grafana,
Prometheus, Python.
