Why I’m a Strong Fit

Requirement	My Experience & Impact
Design & develop full‑stack solutions (Java & Angular)	• Led the end‑to‑end redesign of a flagship B2B SaaS product, migrating from Angular 5 to Angular 12 and refactoring the backend to Spring Boot 2.5. Result: 35 % faster page loads and 20 % reduction in server‑side latency.
Build scalable RESTful APIs with security & performance	• Architected a suite of 150+ REST endpoints using Spring Boot, JWT/OAuth2, and API‑gateway throttling. Implemented circuit‑breaker patterns (Resilience4j) and achieved 99.99 % uptime under peak loads of 10 k RPS.
Translate business needs into technical solutions	• Partnered with product owners and data‑science teams to model complex domain entities (e.g., hierarchical permission trees). Delivered a domain‑driven design that cut feature‑delivery time by 30 % and eliminated duplicated logic across services.
Mentor mid‑level developers	• Managed a cross‑functional squad of 6 developers (2 junior, 2 mid‑level, 2 senior). Conducted weekly code‑review sessions, introduced pair‑programming, and instituted a “Definition of Done” checklist that raised code‑quality metrics (SonarQube rating from B to A‑).
Ensure compliance with coding standards & best practices	• Championed the adoption of Clean‑Architecture principles, automated static analysis (SpotBugs, ESLint) and CI pipelines (GitHub Actions) that enforce 100 % test coverage for new code.
Strong Java (8+) & modern features	• Daily use of Streams, CompletableFuture, Lombok, and Records. Built a reactive data‑processing pipeline with Project Reactor that processes >5 M events/day.
Spring Boot & REST services	• Designed micro‑services using Spring Cloud (Config, Eureka, Sleuth) and Docker/Kubernetes for container orchestration.
Angular (8+) & responsive UI	• Developed reusable UI component libraries with Angular Material and SCSS, ensuring WCAG‑AA compliance and mobile‑first responsiveness.
Microservices & distributed systems	• Migrated monolith to a domain‑driven micro‑service architecture (12 services) on AWS EKS, leveraging Istio for service mesh observability.
JUnit unit & integration testing	• Authored >2 k JUnit 5 tests, integrated with Testcontainers for realistic integration tests, achieving a 95 % pass rate on every CI run.
