Hi, I'm Shubhanshu Singh ๐Ÿ‘‹

I am the Founder of Exemplar, the control plane for harness engineering in Agentic DevOpsโ€”governing AI agents, cutting token waste, and managing MCP tools across the software development lifecycle.

With over a decade of engineering leadership experience as a Principal Engineer and CTO, I specialize in designing autonomous AI multi-agent orchestration engines, policy-driven security, and high-throughput distributed systems.


๐Ÿ’ก What I'm Building & Architecting

  • ๐Ÿš€ Exemplar โ€” AI agent governance and harness control plane (Relay, Automation Studio, DevX Assist, and MCP integration).
  • ๐Ÿง  Agentic Systems & AI Infra โ€” Building multi-agent orchestration, context management, and intelligent model routing to optimize performance and LLM spend.
  • โšก Policy & Fine-Grained Governance โ€” Enforcing zero-trust guardrails, action approvals, and audit trails across developer tools using Open Policy Agent (OPA) and OpenFGA.

๐Ÿ’ผ Experience

  • ๐Ÿš€ Founder @ Exemplar (Nov 2025 โ€“ Present) Building Harnessโ€”an agent governance layer controlling AI agent runtimes with token budgets, tool access rules, and audit trails across LangGraph, CrewAI, and custom agentic stacks.

  • ๐ŸŽฏ Chief Technology Officer @ Sharpsell.ai (Jul 2025 โ€“ Nov 2025) Led technical strategy for an AI-powered enterprise Sales Playbook Automation Platform, architecting intelligent sales enablement tools and dynamic product engines.

  • ๐Ÿ› ๏ธ Principal Software Engineer @ Lowe's (Jan 2021 โ€“ Jun 2025) Led platform initiatives across 8 products and 100+ engineers; built an in-house API Management Portal (Kong), self-service Internal Developer Platform (IDP), GenAI RAG tools, and low-code workflow automation.

    Architected an in-house, zero-storage A/B Testing & Feature Flagging Platform using consistent hashing and CDN edge workers, replacing legacy commercial tools and reducing operational costs at scale.

  • ๐Ÿš€ Founder in Residence @ Entrepreneur First (EF) (Aug 2020 โ€“ Dec 2020) Explored early-stage startup ideas, technical feasibility, and go-to-market strategies within the EF global talent investor cohort.

  • ๐ŸŽฎ Chief Technology Officer @ HalaPlay (Oct 2017 โ€“ Jun 2020) Scaled a cross-platform mobile gaming system to 9M+ registered users and 4M MAU ($150K+ daily transactions). Architected backend throughput from 4K to 8K+ TPS (Node.js/Fastify/K8s) and ETL pipelines (Spark/Kafka), leading to a successful acquisition.

  • ๐Ÿ“ˆ Engineering Lead @ MoEngage (Dec 2014 โ€“ Sep 2017) Engineered real-time ETL pipelines handling 40Kโ€“60K TPS (Kafka & Samza) supporting 35M DAUs. Spearheaded Flows (no-code cross-channel user journey builder) and In-App Native marketing campaign engines.

  • ๐Ÿ’ป Software Engineer @ Junglee Games (Sep 2014 โ€“ Nov 2014) Maintained real-time C# and WCF multiplayer game servers for Junglee Rummy.


๐Ÿ† Track Record & Highlights
