What I'm looking for

I am looking for roles where I can lead requirement engineering and integrations in cross-functional teams, work with microservices and event-driven architectures, and contribute to feature delivery and system design in a collaborative, growth-oriented environment.

I am a system analyst and technical product manager with over six years of experience translating business needs into scalable technical solutions across telecom, fintech, and e-commerce. I specialize in requirements engineering, API and event-driven integrations, and cross-functional delivery.

At IronFx I designed system requirements for multiple microservice projects, led delivery of 30+ new features, and created data structures and mappings for internal reporting and external marketing integrations. At Zendrop I prepared sprint tasks, reverse-engineered service flows, and authored requirements for 8+ integrations including payment gateways and shipping providers.

Previously at FunBox I engineered requirements for back-office automation and documented 15+ legacy system integrations, supporting continuous feature delivery including 20+ accounting updates and numerous client-facing features. I also contributed as a segment manager and technical editor, maintaining documentation and version control for learning materials.

I bring rigorous analytical thinking, hands-on experience with REST, messaging brokers, microservices, and tooling like Kafka, PostgreSQL, Redis, Confluence, and Jira, and a pragmatic focus on delivering reliable integrations and clear, implementable requirements.
