Ronish Paudel
I'm a Full Stack Engineer who ships production web platforms end-to-end with React/Next.js, Node.js, TypeScript, PostgreSQL and AWS. As Lead Full Stack Engineer at Swikar Codes, I own two live products: ProSathi, an expert booking marketplace with payments, real-time chat, MCP integrations and payouts, and SwikarCodes, an LMS that uses FFmpeg for video encoding. I pick technology based on how much it helps the people using the product.
Specialized In
FFmpeg Video Encoding (Node.js)
Media backends in Node.js/Express with chunked parallel uploads to AWS S3 and FFmpeg adaptive-bitrate (HLS) encoding, served through Bunny CDN.
MCP Integrations
Model Context Protocol servers and AI agents that connect LLMs to real product data and tools, used for blog curation, error tracking and workflow automation.
ePayment Integration
Production eSewa and Khalti checkout flows with verification, payouts, invoicing and Nepal-specific TDS logic, plus a guest checkout for non-registered users.
Consumer-Focused Tech
Picking tech that makes things better for end users: faster loads, fewer checkout steps, correct timezones and reliable real-time features, all tracked through real metrics.
