Founder & Engineering Lead Full-time · Remote

2024 — Present

@ Comcent Technologies Pvt. Ltd. · Brahmavara, Karnataka, India

// Bootstrapped startup behind the open-source Comcent CPaaS / contact-center platform

  • Incorporated and bootstrapped Comcent Technologies, taking the Comcent CPaaS / contact-center platform from concept to a working open-source product while owning product direction and company finances end to end.
  • Architected and built the Comcent CPaaS / contact-center platform from scratch using SIP and WebRTC to route and manage live customer calls, with LLM-powered call transcription and analysis.
  • Hired and led an engineering team of up to 5 interns and contractors — sourcing, interviewing, onboarding and mentoring engineers, and growing interns into independent contributors.
  • Planned and scheduled all engineering work: broke the product roadmap into sprint-sized tickets in Jira, assigned work across the team, and drove delivery through structured code review on every pull request.
  • Owned the engineering budget of a self-funded company — contractor compensation, cloud infrastructure (AWS) and tooling — balancing burn rate against roadmap priorities for over two years.

  • Shipped a white-label conversation-analytics portal (SvelteKit) with GPT-powered chat and insights, sold to enterprise customers for call visibility and analysis.
  • Built an MCP server exposing vCon data to AI assistants, and a license-gated enterprise build for commercial distribution.
  • Automated end-to-end deployment to Kubernetes using Helm charts and ArgoCD GitOps, standardizing reproducible releases.
  • Instrumented the pipeline with SigNoz observability, improving performance against measured metrics instead of guesswork.
