01 / SELECTED WORK
Less talk.
More building.
Nine products. Different problems.
The same drive to make things work.
GOOD PRODUCTS START WITH PEOPLE.02 / THE PERSON BEHIND THE CODE
Curiosity first.
Ownership always.
I’m Olajide. You can call me Firewall.
I’m a Lagos-based Senior Software Engineer, Backend & Full-Stack Developer, DevOps Engineer, AI Integration Specialist, and Founder with 6+ years of experience. I bring engineering depth, product ownership, and a practical approach to building software.
My work spans hospital software, diagnostic marketplaces, mobility systems, AI interviews, competitive challenges, and reading-to-action communities. These projects bring me close to the messy, interesting details that make a product useful.
I’m interested in working with founders and teams anywhere in the world: understanding the problem, making thoughtful technical choices, and building something worth putting in people’s hands.

Build across the stack.
Connect usable interfaces to APIs, data models, authentication, and integrations.
Test. Learn. Refine.
Check the important journeys, handle the edge cases, and improve from feedback.

04 / THE HARD PARTS ARE THE WORK
Beyond the
happy path.
Payments need precision.
Chekker’s booking flow connects payment confirmation, retries, and settlements. The engineering lesson: financial rules belong in dependable transactions.
One platform, many users.
Patient, laboratory, and admin experiences need different permissions and interfaces while sharing consistent business rules.
Real workflows are complex.
Clinical care, pharmacy, appointments, and laboratory operations demand more than a good-looking dashboard. The pieces need to work together.
