What I'm looking for

I'm looking to build scalable, secure, user-facing products where I can contribute across frontend, backend, architecture, performance optimization, testing, and cloud deployment workflows.

At D Quanta Labs, I build a Flight Booking App and CRM with Next.js, React, TypeScript, and Node.js. My frontend and API optimizations improved responsiveness by about 25%, while in-memory caching cut average API latency from 800 ms to 520 ms.

Previously at UNICLOUD LABS, I developed and maintained MERN applications, RESTful APIs, responsive React interfaces, and optimized MongoDB schemas and queries. I enjoy working across architecture, API design, state management, debugging, code reviews, and Agile delivery.

I also build privacy-focused products, including Torvi AI, a Windows-native context-aware desktop assistant using Tauri, Rust, React, encrypted SQLite storage, and RAG-based search. My work includes secure OAuth integrations, OWASP-aligned backend design, asynchronous RabbitMQ workflows, testing, and CI/CD deployments.
