Hi there, I am a strong fit for this scope because I have designed and shipped production-grade REST and GraphQL APIs with strong security and performance standards. I have hands-on experience building scalable backend services using Node.js and Python (Django/DRF and Flask), including structured database design and optimized query handling. I focus on clean architecture, versioned endpoints, authentication with JWT/OAuth, input validation, rate limiting, and proper logging to ensure secure and maintainable APIs. I reduce risk by documenting schemas clearly, writing tests for critical endpoints, and designing APIs with future extensibility and load scaling in mind. I am available to start immediately and can share relevant API projects and architecture samples upon discussion. Regards Chirag

@vishala81

I’d be happy to help with this. I’m a backend developer with hands-on experience designing and building secure, scalable APIs, primarily using Python (Flask, Django, FastAPI) and Java (Spring Boot). My focus is always on clean API design—well-structured endpoints, consistent request/response models, and robust error handling—so both frontend teams and external consumers can integrate smoothly. I’ve built and maintained RESTful APIs end to end, handled database design and optimization (MySQL/PostgreSQL), and implemented authentication, authorization, and rate limiting following security best practices. In previous projects, I’ve delivered APIs for dashboards, automation tools, and SaaS backends where reliability and performance were critical. I pay close attention to validation, logging, and edge cases, and I write clear, well-documented code that’s easy to maintain and extend. I’m comfortable taking ownership of server-side logic, database interactions, and API security from design through deployment. I can share relevant examples of past API work and outline how I’d approach your specific requirements if you’d like.
