Dhruvil Shah

Final-year CSE student with hands-on experience building REST APIs, relational databases, and backend systems. Seeking a .NET Intern role to apply strong OOP fundamentals, SQL knowledge, and backend engineering skills in a production environment. Proficient in C# and ASP.NET Core — comfortable picking up new frameworks quickly, taking ownership of features, and understanding systems end to end.

Backend Developer Intern at Bintech Services (2025-04 – 2025-06)

• Engineered RESTful API endpoints that connected frontend clients to backend services — applied OOP principles (classes, encapsulation, separation of concerns) to keep business logic modular and independently testable.
• Designed and optimised SQL schemas — wrote complex queries with JOINs, applied indexing strategies on high-traffic tables, and reduced average query execution time on key user flows through structured query analysis.
• Implemented secure authentication and session management — built server-side validation, JWT-based session handling, and structured error responses that maintained data integrity and backend reliability under concurrent requests.
• Diagnosed and resolved backend performance bottlenecks — independently identified root causes of slow API responses and database timeouts, applied fixes, and validated improvements through Postman and log analysis.
• Shipped features consistently in Agile sprints — participated in daily standups and sprint planning; adapted quickly to changing requirements and delivered tasks on schedule across a cross-functional team.

Web Developer Intern at Bintech Services (2024-06 – 2024-07)

• Built and maintained server-side web modules — developed backend logic for dynamic page rendering, integrated REST API endpoints, and ensured consistent data flow between the database and application layer.
• Implemented input validation, server-side error handling, and structured HTTP responses — reinforcing data integrity and backend reliability across web application workflows.
• Collaborated on database schema design and wrote SQL queries to support feature requirements — applied normalisation principles and ensured relational integrity across tables.
• Debugged backend issues and API failures using browser DevTools and Postman — traced request-response cycles, identified root causes, and applied targeted fixes to improve system reliability.
• Worked within an Agile team to translate stakeholder requirements into backend specifications — contributed to sprint planning and maintained clear documentation for API contracts and data models.
