I specialize in building scalable, secure, and high-performance systems using Java (8–17), Spring Boot microservices, Angular, REST APIs, Cloud platforms (GCP/AWS)—and real-time communication systems using WebRTC. My background spans fintech, healthcare, telecom, e-commerce, and government projects, where I’ve handled everything from greenfield architecture to refactoring legacy systems and scaling platforms used by thousands of users. Real-Time & Event-Driven Systems In addition to traditional enterprise systems, I work with WebRTC-based real-time solutions: WebRTC: One-to-one and group video/audio calling, screen sharing, low-latency streaming, signaling servers, secure real-time architectures Kafka: High-throughput event pipelines, asynchronous microservice communication, stream processing, audit/event sourcing patterns, and fault-tolerant data flows - One-to-one and group video/audio calling - Screen sharing and low-latency streaming -Signaling servers and backend integration -Secure, scalable real-time architectures -WebRTC integrated with modern web apps and cloud backends -This makes me well-suited for products involving: -Video conferencing -Live collaboration tools -Telehealth platforms -EdTech / remote learning -Real-time dashboards and streaming workflows What I deliver: -Clean, maintainable, production-ready code -Scalable microservice architectures -Secure applications (JWT, OAuth2, role-based access) -Cloud-native solutions on GCP & AWS -Real-time systems using WebRTC -End-to-end development: backend → frontend → deployment -Clear communication and predictable delivery -Core Skills -Backend: Java, Spring Boot, Spring Security, Microservices, REST APIs -Frontend: Angular (2–12), HTML, CSS, TypeScript -Real-Time: WebRTC, signaling design, low-latency systems -Cloud & DevOps: GCP, AWS, Docker, Jenkins, CI/CD -Data: MySQL, PostgreSQL, Oracle, BigQuery, Kafka -Architecture: System design, performance optimization, API design I work with an ownership mindset—treating your product as if it were my own. Whether you need a real-time communication feature, a cloud-native backend, or a full-stack platform built from scratch, I focus on long-term quality and business impact, not just “getting it done.” If you are looking for a reliable senior engineer who can think in systems, communicate clearly, and deliver production-grade results, I’m ready to help you build. menos -
