AI Engineering Leadership Developer Experience Columbus, OH

Sunny Kolattukudy

I drive the shift to AI-native development across engineering teams — with the platforms, standards, and coaching that help teams ship faster without losing control. I'm a player-coach: I set the direction, and I still architect and build the systems myself.

How I Lead

Experience

  1. Verifiable Staff Software Engineer · Developer Experience Guild Leader · 2025 – Present
    • Lead the Developer Experience Guild, driving the move to AI-native engineering — teaching teams to work effectively with Claude Code and Codex, and building the guardrails that make it safe.
    • Cut PR review time by 30+ minutes per pull request with an AI code review pipeline on Claude with automatic Codex fallback — a reusable GitHub Actions workflow that keeps review and CI/CD standards running org-wide.
    • Shipped Source Warden to production: AI ops that triages Datadog alerts and hands the owning engineers the fix, the investigation, and screenshot proof — replacing manual on-call triage.
    • Architected the Engineering Internal Developer Portal in .NET and Blazor WASM — agent skills, self-healing workflows, and E2E test history give engineers and coding agents one realistic, shared environment.
  2. Arcoro Principal Software Engineer · 2021 – 2025
    • Set the technical vision for Arcoro Hub — now the company's central product platform — built to scale 10× on .NET, Blazor Hybrid WASM, and .NET MAUI, with a live sync bridge to legacy applications.
    • Tripled feature delivery speed across all product teams by building a new SPA and API for ExakTime in Angular and .NET, without disrupting existing users.
    • Rewrote a failing event-driven architecture on Azure Event Hubs, Functions, and Storage — 98% performance improvement and an end to customer data loss.
    • Moved the team to in-memory SQLite EF Core integration tests — 95%+ faster than Selenium end-to-end runs, and the foothold for TDD.
  3. PNC Bank Principal Software Engineer · 2016 – 2021
    • Took QA deployments from once a month to 4+ per day by building CI/CD pipelines with Azure DevOps and IBM UrbanCode Deploy.
    • Led rewrites of two legacy institutional asset management systems into .NET — 86%+ faster on workloads handling millions of dollars per hour, passing internal audit.
    • Coordinated multiple teams over a year to roll out Ping Identity across four applications.
    • Mentored a developer focused on code quality and simplicity — who now leads a team of 7 on the same applications.

From medicine to music to software.

The medicine chapter was about learning how to help people well. Case Western Reserve University and Cleveland Clinic's Lerner College of Medicine gave that a rigorous foundation: understand the problem fully before acting, and know that getting it wrong has real consequences for real people.

Co-founding Deadiron, a melodic thrash metal band, added something different — the experience of building something creative with a group of people where everyone has to be fully invested for it to work. A band that's clicking is a good model for what a high-functioning team looks like.

Software turned out to be where both of those things fit — the problems are technical, but the work is still about helping people and building things together. That became the foundation for a decade of engineering across finance, HR tech, and health credentialing automation.

That experience runs through a consistent pattern: modernize the systems, raise the standards, and grow the people — so every engineer can contribute, and the whole organization gets better, not just the code.
