Staff Engineer · AI agents · Distributed systems

I build AI agents and the platforms they run on.

At Stamina.io I designed Zara, an AI SDR agent that enriches 20K leads a day and doubled reply rates, and the workflow engine behind 5,000+ automations a day. Before that, LLM-powered search over 1M+ documents for Fortune 500 sales teams and real-time video for 100,000 concurrent users.

Career Journey

Staff Engineer — Head of Engineering

Stamina.ioFull-time ContractJun 2025 - PresentNew York, United States · Remote
  1. Founding Backend Engineer — Lead Jun 2025
  2. Staff Engineer — Head of Engineering Apr 2026

AI sales, CRM and marketing SaaS used by 1,000+ customers in 50+ countries.

Designed and built Zara, Stamina's AI SDR agent (LangGraph, tool calling, structured outputs): enriches 20K leads/day, doubled reply rates and cut lead response time from 24 hours to instant for 1,000+ customers in 50+ countries.
Cut LLM cost per lead by 70% with per-task model routing: bulk per-row work on small models, larger models only for classification and spec generation, with LLM evals and guardrails (schema-validated outputs, model fallback, confidence-gated human escalation) holding output quality.
Architected the workflow automation engine (5,000+ workflows/day, 50+ triggers and actions, 10+ integrations) to start exactly one run per event on at-least-once delivery: transactional outbox to Google Pub/Sub, layered dedup in PostgreSQL, a durable step machine with leases, version pinning and at-most-once CRM writes, and stateless, autoscaling workers with connection pooling to protect the database.
Rebuilt cold-email sending (~30K sends/day) so concurrent senders can't break per-mailbox limits or send twice: atomic Redis Lua reservations, crash-safe send IDs, a six-class failure taxonomy with per-inbox circuit breakers, and a rotating exit-IP pool.
Designed the credit ledger behind usage billing: serializable, idempotent spends across concurrent workers, expiring grants spent soonest-first, an append-only ledger enforced in the database, and Stripe sync that survives late and duplicate webhooks.
Built the Twilio power dialer used by 200+ customers making 5,000+ calls/day: row-locked lead claims so no lead is dialled twice, signed per-call tokens re-checked in the voice webhook, and per-brand Twilio subaccounts.
Owned infrastructure on Kubernetes, Terraform and AWS with per-PR preview environments, a PR check that boots the full 20-service fleet, and OpenTelemetry/Prometheus/Grafana observability; kept 99.9%+ uptime and cut cloud spend by 40% by scaling queue workers to zero when idle.
As Head of Engineering, led the 10-engineer team, reported to the CEO, and owned the technical roadmap, design reviews (ADRs), weekly releases, on-call and incident response; shipped SSO/OAuth2, RBAC and an OAuth 2.1 MCP server for larger accounts.

What Colleagues Say

Colin managed Govind directly at Nesh · July 3, 2025

Govind was an incredible asset on the Nesh team and a wonderful colleague to work with. He took full responsibility for every area that he worked on, and constantly provided us with true software engineering rigor: attacking tech debt, designing for maintainability, enhancing availability, and identifying risks long before they became production problems. I quickly found that Govind could take the thorniest, most confusing problems and return promptly with bulletproof forever solutions already implemented. He has a true engineer mindset, and in addition to his impressive skills he was a very positive presence on the team, leading by example and collaborating actively.

Govind gets things done, communicates well, and writes clean code. He has a positive attitude and makes it fun and easy to work with him. He also possesses strong problem solving skills and always gets things done. Happy to recommend him for software engineering related roles.

Siddhartha worked with Govind on the same team at Nesh · May 2, 2025

I'm excited to recommend Govind, who joined Nesh as a Full-Stack Developer and quickly became indispensable. Govind architected and shipped a suite of AI-powered agents — everything from product recommendation and comparison engines to account-planning and cross/upsell tools — that unlocked new revenue streams and delighted our customers. His deep technical chops let him move from concept to production in record time, and his clean, maintainable code kept our platform rock-solid. What really sets Govind apart is his sharp intellect and candid collaboration style. He iterates at great speed, isn't afraid to speak up when he sees a better solution, and helps the whole team level up by sharing his insights. He plugged into our cross-functional squad seamlessly and raised the bar for the rest of us. Any organization looking to accelerate its AI roadmap and build robust, user-centric features would be lucky to have Govind on the team.

About

Beyond Engineering

What I do when I am not shipping.

Govind Sharma outside work
Govind Sharma

Outside work I travel, train at the gym, and build small products of my own. All three keep me honest about what real users need.

Travel

New cities and local food whenever I can. It is a regular reminder that users live in very different contexts from mine.

Fitness

I train on a fixed routine. Showing up consistently beats any single great session, in the gym and in engineering.

Building Tools

Side products like FastBowlingLab keep me close to the whole job, from first idea to real users.
