What I'm looking for

I’m looking for a role where I design event-driven, cloud-native systems (REST/gRPC, Kafka), improve performance, and strengthen secure architecture through CI/CD—ideally with opportunities to lead technical direction and mentor teams.

I’m a Senior Software Engineer focused on building reliable, cloud-native systems that turn data and operations into actionable outcomes. At AGX Technologies, I developed information dashboards and designed REST APIs with OpenAPI using Spring Boot, alongside strong CI/CD practices (linting, vulnerable library scanning, e2e testing, semantic versioning).

I also bring deep experience with distributed, event-driven architectures. At Goldman Sachs, I developed event-driven distributed APIs, migrated on-prem applications to AWS and GCP, implemented gRPC APIs, and managed monorepos with Bazel. I’ve profiled and optimized Java performance by up to 50% using JMeter and Flight Recorder, and I’ve implemented secure secret management with Hashicorp Vault.

Across leadership and product-building roles, I’ve shipped systems end-to-end—from architecture and mentoring to delivery impact. As a Technical Team Lead, I championed TDD (80% code coverage) and improved performance and cost (Redis reduced app loading times by 30%, and query refactoring reduced cloud costs by 35%); as Cofounder/CTO and CDO at EzyAgric, I helped build platforms used by 60,000+ smallholder farmers and enabled offline usage with caching.
