What I'm looking for

I seek roles building scalable SaaS or real-time systems with strong engineering practices, cloud-native tooling, and opportunities to work on AI-driven automation and architecture.

I am a Full Stack Developer with 2+ years building scalable multi-tenant SaaS platforms, real-time communication systems, and cloud-native architectures. I focus on clean architecture, performance, and reliable integrations across messaging and billing systems.

At Variance Infotech I engineered tenant-isolated backends with Node.js, PostgreSQL (Prisma), Redis, and real-time sync using Google Pub/Sub and Redis Streams, built usage-based billing, RBAC schemas, and an AI voice assistant using OpenAI and AWS Polly.

I have also worked on high-traffic on-demand platforms using Node.js, Angular, and MongoDB, and delivered projects involving image-similarity search, AWS deployments, and integrations with WhatsApp Cloud API, Twilio, Stripe/Razorpay, and Firebase.
