Backend / QA Engineer · Go, Python & APIs

Nairobi, Kenya · Open to backend and API roles

What I build

I build backend systems that teams can review, test, deploy, and maintain—from REST APIs and authentication to database design, integrations, and scheduled workloads.

My strongest stack is Go, Python, TypeScript, PostgreSQL, and Docker. I also bring hands-on QA and API security experience, which means I think about failure cases before software reaches users.

What I bring to a team

One engineer who can connect business workflows, backend implementation, and production confidence.

Backend systems

APIs, authentication, relational data models, integrations, and maintainable service boundaries in Go and Python.

Delivery mindset

Dockerized workloads, cloud deployments, environment configuration, and technical documentation that helps other developers contribute.

Quality and security

API testing, defect isolation, rate limiting, validation, and practical security checks with Postman, OWASP ZAP, and Burp Suite.

Selected work

Four relevant projects chosen for the engineering decisions they demonstrate—including transparent individual and team contributions.

UniNotes Study Platform

A Django platform that organizes university notes and past papers around schools, departments, courses, units, and authenticated contribution workflows.

Proof beyond the screenshots

Each case study links to source code and a live product where one is available. For a closer technical review, see the HIMS OpenAPI specification, HIMS route and repository tests, and my API testing and security lab.

My approach is consistent: understand the workflow, design clear boundaries, build for verification, and leave the system easier for the next developer to operate.
