Backend-focused Software Engineer

Full-stack software engineer (SDE) with a backend focus — system design, REST API development, database architecture, and product features that hold up under real usage. Comfortable across the MERN stack and Python/Django, with production experience in both. At Reospark Technology, I build and maintain internal admin dashboards across multiple client projects using Django, Django REST Framework, and Next.js, design MySQL database schemas for multi-client data isolation, and own end-to-end delivery on 3 client engagements — requirements through iteration on client feedback. Before that, at Vomyra AI, I built real-time voice AI agents using Node.js, WebSockets, and FFmpeg, and cut latency enough to improve streaming/transcription throughput by 60%. Outside work, I build production-shaped side projects rather than tutorials: LinkFlow, a multi-tenant SaaS platform (Next.js, PostgreSQL, Redis, BullMQ, Stripe) with tenant isolation and async job processing; and Clariv, a full-stack document processing platform (Next.js, Node.js, MongoDB, Google GenAI, OAuth) with AI-powered summarization. I prefer boring solutions that scale over clever ones that don't, and care more about system design and long-term maintainability than tools or titles.
