I’m a Senior Backend Developer and Team Lead with over 3 years of experience building scalable, secure, and maintainable backend systems using Java, Spring Boot, and microservices architecture. I’ve led backend development for enterprise-grade systems and worked closely with cross-functional teams to design and deliver mission-critical applications in fintech and education domains.
My Core Stack Includes:

• Languages & Frameworks: Java (11+), Spring Boot, Spring Cloud, JPA, Hibernate
• Databases: PostgreSQL, MySQL, Redis – optimized complex queries and indexing
• Architecture: REST APIs, Microservices, Clean Architecture, Domain-Driven Design (DDD)
• Tools: Docker, Kubernetes (K8s), Jenkins, Git, Maven

Team Lead Highlights:
As a backend team lead, I’ve been responsible for:

• Breaking down large features into epics, tasks, and sprints using Agile methodology.
• Coordinating with frontend, QA, DevOps, and business analysts to deliver on time.
• Performing system design for scalable services such as checkout systems, LMS modules, and user management with security and extensibility in mind.
• Reviewing architecture diagrams, planning database scaling, and forecasting resource usage.

Performance Optimization:
I routinely analyze and improve performance by:

• Profiling SQL queries and tuning database indexes.
• Reducing memory consumption and request response time.
• Implementing caching layers and connection pooling strategies.

I believe great software is built with great communication. I make sure to:

• Provide regular updates with clarity and transparency.
• Break down technical concepts so stakeholders understand what’s being delivered.
• Actively listen and adapt quickly to feedback and changing priorities.
