Cloud Systems Engineer & Backend Developer · Lagos, Nigeria 🇳🇬
AWS Certified Solutions Architect – Associate
I design, automate, and operate reliable cloud infrastructure, distributed backend systems, and containerized platforms. My work centers on building maintainable self-hosted services, reproducible Infrastructure as Code, and resilient APIs that bridge cloud operations with backend software engineering.
- Postgraduate Studies: MSc in Computer Science from University of East London.
- Cloud Architecture & IaC: Provisioning modular multi-environment infrastructure with Terraform, orchestrating containerized workloads with Docker & Kubernetes, and enforcing zero-trust server environments.
- Backend Systems & Integrations: Architecting robust services using Python (Django, FastAPI), message brokers (Celery), relational databases (PostgreSQL), and secure object storage via AWS S3.
- Observability & Reliability: Designing end-to-end monitoring stacks using Prometheus, Grafana, Loki, and native cloud telemetry to minimize MTTR and maintain operational visibility.
