I am a skilled Backend Developer with a strong background in PHP, Python, and database design. I specialize in creating efficient, scalable backend solutions and optimizing database performance. My expertise includes complex SQL query writing, database schema design, API development, and backend logic implementation. I have experience with RESTful API development, version control (Git), and web frameworks like Laravel and FastAPI. I work with various database types, including SQLite, MS SQL, MySQL, and PostgreSQL, to ensure seamless data integration and functionality across platforms. I have improved application performance and scalability through backend optimization and effective database design. By reducing SQL query execution time by 30% and conducting smooth database migrations, I’ve enhanced data accessibility and reliability. My work also includes developing backup strategies and collaborating on stored procedures and backend logic for efficient operations.

Most ERPNext projects go over budget and under-deliver — not because the software is wrong, but because the implementation ignored how the business actually operates. That's the problem I've spent 13 years fixing. I build ERPNext implementations and Spring Boot backend systems for startups, SMEs, and enterprises that need things done right the first time. I'm Frappe Certified on ERPNext V15, and I've completed 38+ projects on Upwork with a 100% Job Success Score across $90,000+ in work — which means clients come back, and they refer others. 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐚𝐝𝐝 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐯𝐚𝐥𝐮𝐞: On the ERPNext side: end-to-end implementations, custom DocTypes, workflow automations, approval hierarchies, print formats, custom scripts, and REST API integrations with third-party tools. I understand the Frappe framework deeply enough to build what the standard modules can't. On the backend side: Spring Boot REST APIs and microservices with proper security (Spring Security, JWT, RBAC), JPA/Hibernate, clean architecture, and production-ready deployments. I've also handled Liferay 6.2/7.x portal development and Java + React/Angular enterprise portals for clients who needed both ERP and a custom frontend layer. What separates working with me from working with a developer who just executes tickets: I ask the two questions most developers skip before starting — what does your current process actually look like, and what does failure cost you? That conversation shapes everything and usually saves weeks of rework. Currently available. I reply within a few hours.

I'm a seasoned full-stack developer with over 12 years of professional experience in designing and developing robust, scalable solutions across web, mobile and database platforms. I’ve successfully delivered complex projects for clients in both government and public domains, with a strong focus on security, performance and maintainability.
