At Heaptrace Technology, I delivered Java and Spring Boot microservices for a European energy-management platform, including invoice and reporting services. I also optimized PostgreSQL queries across GCP and Docker deployments, reducing average query response time by 25%.
On the same platform, I built microservices for electricity monitoring, energy pricing, and analytics, and designed REST APIs with Swagger/OpenAPI. I introduced Hazelcast caching for analytics dashboards, reducing repeated database load by an estimated 30%.
For a USA client’s text-to-diagram tool, I built a platform that generates flowcharts, sequence diagrams, and class diagrams from markdown-style text. I developed reusable Svelte components and shipped real-time collaboration features, helping cut users’ manual diagramming time by an estimated 40%.
I also built NFC-based health-record sharing features for a HIPAA-compliant healthcare application and deployed it to AWS through Jenkins CI/CD. At Heaptrace Technology, I progressed through four promotions and currently serve as a technical lead, guiding microservice design and delivery.
