I enjoy building fast, end-to-end systems and shipping real features. Recently, I built a real-time voice-based application using Python, FastAPI, WebSockets, PostgreSQL, ElevenLabs widget, and React, where users interact via natural speech to navigate and manage content in real time. I handled backend services, API design, database models, real-time pipelines, and deployment-ready logic. (Project can be found on my github: github.com/Prem-11?tab=repositories) I’ve also worked on Asobu, a multiplayer sports platform, contributing to backend APIs, triggers, and notification logic focusing on reliability and performance. (More information can be found in my resume) Along with development, I have close to 2 years of experience in manual software testing, which helps me write more reliable backend code, think through edge cases early, and collaborate effectively with QA and frontend teams. Additionally, I previously started and ran a QA service (Test Elevate) from scratch, where I worked directly with founders to understand real end-user needs and deliver targeted testing solutions. This experience sharpened my eye for edge cases, production reliability, and customer-driven development. ( I’ve shared parts of this journey on LinkedIn: linkedin.com/in/prem-sangle-0ab76a1a7 ) I’m available to join immediately. Looking forward to your response.
