🧠 About Me

I'm a Software Engineer from πŸ‡ΈπŸ‡± Freetown, Sierra Leone, focused on engineering systems that are reliable, resilient, and built to scale. I specialize in backend architecture, cloud infrastructure, and securing distributed systems β€” from designing APIs to shipping containerized workloads to production.

  • πŸ”­ Currently working on CoursePaddy as Lead Backend Engineer & DevOps β€” previously shipped KeneCare (telemedicine platform)
  • 🌩️ Hands-on experience deploying systems to AWS / cloud platforms with CI/CD pipelines
  • πŸ” Passionate about system security β€” auth workflows, secure data sharing, least-privilege infra
  • πŸ—οΈ I think in systems: queues, caches, health checks, failover, and observability
  • πŸ’‘ Motto: Imagination is everything β€” but execution is what ships
  • πŸ’Ό Open to work β€” actively seeking Backend or DevOps Engineer roles (remote-friendly)

πŸ’Ό Open to Work

I'm actively looking for my next opportunity as a Backend Engineer or DevOps Engineer β€” remote or hybrid.

If you're building something ambitious and need someone who can architect backend systems, own cloud infrastructure, and ship production-grade software, let's talk.

What I bring to the table:

  • βœ… Proven experience shipping real products used by real users
  • βœ… End-to-end ownership β€” from API design to cloud deployment
  • βœ… Strong grasp of system security, distributed patterns, and observability
  • βœ… Collaborative team player who has worked in cross-functional teams
