I’m Nainil Oza, a Software Engineer based in Ahmedabad, where I build and support production-grade web applications end-to-end—from requirements and API/database design to testing, deployment, and production issue resolution. I work across full-stack development with a strong focus on backend services, data modeling, security, and performance. In my recent work, I’ve developed live React and Node.js/Express systems with PostgreSQL/MongoDB, Redis, and Elasticsearch, and I’ve integrated major payment and document workflows using Stripe, PayPal, DocuSign, and messaging tools like SendGrid and SMS. I enjoy turning complex CRM and financing processes into reliable, scalable platforms, including features like OTP authentication, webhooks, analytics, and multi-tenant-friendly architecture.…I’m Nainil Oza, a Software Engineer based in Ahmedabad, where I build and support production-grade web applications end-to-end—from requirements and API/database design to testing, deployment, and production issue resolution.
