Hey, I'm Gyanendra, a Software & AI Engineer specializing in Real-Time AI, Voice Pipelines, and Edge ML. I care about clean backends, systems that scale, and building products that solve real problems.

I've worked across the full stack — React.js, Next.js, Nest.js, FastAPI, Docker, PostgreSQL and I've led teams, shipped production features, and debugged things at 2am. Most recently I was at Vizuara AI Labs working on a voice-based AI interview platform (TTS/STT, WebRTC, GenAI).

Right now I'm deep into ML model training and deployment — learning the full pipeline from training to serving to monitoring. Still learning, still building.

🟢 Open to work — looking for a team where I can contribute meaningfully and keep growing.

I'm also open to collaborations, open source, or just a good engineering conversation. If something here resonates — reach out.

Experience

Software Development Engineer - 1 (Promoted from Intern) • Oct 2025 – Mar 2026

  • Built an end-to-end AI-powered Interview Platform using GenAI and Pipecat for real-time conversational assessments with dynamic question generation.
  • Designed a low-latency voice pipeline integrating STT(moonshine, faster-whisper)/TTS(Kororo, Kitten TTS) models, Pipecat, WebRTC streaming, and VAD for seamless audio-based interviews.
  • Implemented context-aware LLM pipelines for adaptive questioning and follow-ups, improving interview quality and engagement.
  • Migrated a legacy WordPress EdTech platform to a scalable React + Firebase architecture, reducing page load time by 60% and supporting 2,000+ active users.
  • Built a modular backend using Firebase (Firestore, Auth, Storage) ensuring secure and scalable data handling.
  • Integrated Razorpay & PayPal payments with secure webhook-based verification.
  • Developed Pub/Sub–driven email automation processing 500+ daily notifications, comment system, and comprehensive course/lesson analytics (engagement, completion rate, time spent).
