About

I build scalable, high-performance applications that millions rely on daily. As a Senior Full Stack Engineer with 4+ years of experience, I specialize in architecting enterprise systems using Java, Spring Boot, and React. My work serves 100,000+ daily users across microservices platforms. 💡 What I Bring to the Table Backend Excellence: I design RESTful APIs and microservices that handle massive scale. I've improved system performance by 35% through strategic caching with Redis and database optimization. My code has reduced API response times from 800ms to 150ms in production systems. Frontend Craft: I build responsive React applications with TypeScript that users love. I've created 50+ reusable components that accelerated development speed by 30% and published NPM packages adopted by 50+ developers. Production Quality: I ship reliable systems. Through comprehensive testing (85%+ coverage) and Azure Monitor integration, I've reduced production incidents by 40%. 🚀 Recent Impact • Led Client Portal architecture - Built a full-stack platform serving 12+ microservices, reducing P95 response time from 1.2s to 400ms through caching and query optimization • Built Gen-AI Pharmacy platform - Developed a healthcare system processing 10,000+ medical files daily with 94% data accuracy, integrating Spring Security with JWT authentication • Top Performer Q3 2024 - Delivered critical features ahead of schedule with 95%+ sprint completion rate 🛠️ Technical Arsenal Backend: Java 8/11/17, Spring Boot, Spring Security, Spring Data JPA, Hibernate, Microservices, RESTful APIs, Kafka, Redis Frontend: React.js, TypeScript, Redux, JavaScript (ES6+), HTML5, CSS3, Responsive Design Data: PostgreSQL, MySQL, MongoDB, Query Optimization Cloud & DevOps: Azure (Certified), Docker, Kubernetes, CI/CD, Azure Monitor, Grafana 📈 Career Growth Promoted 3 times in 4 years at Nagarro (Trainee → Associate → Senior Engineer → Associate Staff Engineer), consistently exceeding expectations. 📜 Certifications: Azure Fundamentals (AZ-900) | Currently pursuing: AZ-204 & Oracle Java SE 11 🤝 Let's Connect I'm passionate about building systems that scale, mentoring engineers, and solving challenging technical problems.
