Software developer with 5+ years of experience building robust and scalable web applications, with a strong focus on backend architecture and fullstack development. I have delivered projects ranging from e-commerce platforms and management systems to payment gateway integrations and third-party API connectivity.
Python / Django β€” Full-cycle web application development with Django and Django REST Framework, covering authentication systems, ORM design, custom admin panels, and external service integrations. Experienced with HTMX to build dynamic, server-driven interfaces without the overhead of a full SPA β€” achieving interactive pages with minimal JavaScript complexity.
Java / Spring Boot β€” Microservices and REST API development with Spring Boot, including security implementation with Spring Security, data persistence with JPA/Hibernate, and deployment in enterprise environments.
Node.js β€” API and real-time service development using Node.js and Express, asynchronous event handling, and integration with both SQL and NoSQL databases.
Frontend β€” Semantic HTML5 and CSS3, Tailwind CSS and Flowbite for responsive, production-grade interfaces. HTMX integration for server-side interactivity without heavy frontend frameworks.
Databases β€” PostgreSQL, MySQL, SQLite. Schema design, migrations, and query optimization.
Tooling & Deployment β€” Git, REST APIs, Docker (working knowledge), deployment on Railway, AWS, and Linux-based VPS environments.
