At Sedulous Softech, I designed seat-locking logic for high-concurrency bookings and implemented WebRTC audio and video calling. Through WebHubpoint, I delivered production platforms across several domains, including Fitspot.in, and integrated payment gateways processing Rs. 10L+ in monthly transactions.
