What I'm looking for

I’m looking for Remote roles (US/EU/LATAM) as a Senior/Staff/Tech Lead, focused on Angular & Java-heavy stacks in FinTech/PropTech/SaaS—leading migrations, microservices, and performance + observability with a strong testing culture.

I’m a Full-Stack Software Engineer with 6+ years building enterprise web applications with Angular (v8 → v21) and Java Spring Boot microservices. I’ve led legacy modernization—migrating monoliths to microservices, refactoring Angular toward standalone components, and optimizing batch processing from “days down to hours” with measurable impact like reducing heap from ~150 MB to ~2 MB per file.

I bring a strong engineering foundation across CI/CD, Docker, Kubernetes, and cloud deployments on Huawei Cloud and AWS, plus rigorous testing and observability (Prometheus/Micrometer, OpenTelemetry, structured logs with trace correlation). As Co-founder & Tech Lead of AdminSmart, I designed a multi-tenant SaaS with role-aware RBAC, tenant isolation via JWT HttpOnly cookies, and an event-driven pipeline for payments and delivery—always prioritizing performance, security, and maintainability.
