Backend-focused software engineer building secure payment, housing, and transport systems.

What I'm looking for

I’m looking for a role where I can build secure backend systems and APIs with Java/Spring, work with PostgreSQL-style data layers, and ship dependable integrations in a collaborative team that helps me grow.

I’m a software engineer trained in Information Technology, and I focus on building reliable backend systems that connect real-world users to the right workflows. Through my projects, I’ve learned to prioritize security, integration quality, and maintainable APIs.

In Paybridge, I built a payment orchestration system that lets merchants integrate once and connect to multiple providers. I implemented secure authentication, merchant onboarding, API key lifecycle management, idempotent payment processing, and webhook verification with replay protection. I also developed and validated core backend flows using Spring Boot, PostgreSQL, Redis, and integration tests.

I continue to apply the same backend discipline in Carebnb, Keks, and API-focused work like the “Virtual Book Store API.” I use Spring Boot with PostgreSQL, Spring Security, OAuth 2.0 Resource Server for JWT decoding, Hibernate, and Thymeleaf—then troubleshoot integration issues (like image upload failures) to improve reliability and end-to-end results.

Carebnb Shared Refugee Housing

Carebnb

Mar 2025 - Present (1 year 1 month)

Implemented Carebnb, a shared refugee housing system connecting refugees with civilians willing to help. Built the backend with PostgreSQL, Spring Security OAuth 2.0 Resource Server for JWT decoding, Hibernate, OpenSSL-generated RSA keys, and Maven, and used Thymeleaf for frontend-backend communication while addressing integration issues (e.g., image upload failures) to improve reliability.
