Experience

1. Everon (formerly DigiOp)

   Mar 2024 – Present

   Principal Engineer

   • Lead AI engineering practices across a software organization of roughly 8 engineers; previously led a 4-person AI team and a 4-person backend team, and now lead a backend team alongside a Principal Architect.

   • Built Agent Smith, an internal multi-agent SDLC platform that automates ticket intake, repository analysis, testing, implementation, validation, code review, pull-request creation, and Azure DevOps state synchronization with explicit human control points.

   • Built internal leverage tools including Carbon-CLI, CarbonMCP, IDE extensions, AI-assisted Azure SQL diagnostics, and secure Support self-healing utilities; Support tooling has eliminated tens of hours of recurring developer interruption and is estimated to approach 100 hours saved in a year.

   • Architected event-driven SQL entity propagation with Azure Functions and Event Grid so downstream services, caches, and databases can react independently to domain create/update/delete events.

   • Improved platform resilience through proactive Azure/App Insights alerting into Slack, ingestion anomaly detection, custom rate limiting, ADX-throttling mitigation with distributed caching, DI startup validation, and resolution of a critical WebApi thread deadlock.

   • Modernized delivery and security by moving Function Apps from manual publishing into Azure DevOps pipelines, automating integration tests before slot swaps, implementing authorization middleware, moving secrets to Key Vault/App Configuration with Entra RBAC, and encrypting third-party credentials with customer-specific keys.

   • Reduced cloud and database pressure through performance profiling and storage redesign, including the 18-minute-to-38-second review-loading improvement and an AppendBlob-to-BlockBlob migration for expensive case uploads.

2. Pie Insurance

   Jun 2022 – Apr 2024

   Senior Full Stack Engineer

   • Worked across AWS-hosted business systems written in Go, Node.js, and C#, sharing ownership of a diverse application portfolio with a strong engineering team.

   • Expanded cloud and cross-language experience while contributing hands-on to production systems and leading an early internal Lunch & Learn on practical generative AI.

3. DigiOp

   May 2018 – Jun 2022

   Application Architect

   • Helped grow Carbon, a security analytics platform, across Angular, C#/.NET, SQL Server, Cosmos DB, Azure services, and multiple product integrations; guided developers and performed architecture/code reviews.

   • Designed a reusable Playwright frontend testing platform with generic, customer-specific, and all-customer runners; secured authentication tokens in Azure Key Vault and integrated execution into CI.

   • Architected and delivered cloud, mobile, desktop, identity, data, and operational capabilities while working closely with Product, Support, implementation teams, and engineering.

4. EduSource

   Jan 2015 – May 2018

   Software Engineer / Consultant

   • Worked in a consulting-oriented role across client systems while mentoring college and early-career developers.

   • On a critical engagement where a company had lost its development staff and lacked usable source code for hundreds of deployed web applications, reverse-engineered compiled .NET assemblies and IL, extracted dependencies, and mapped applications to stored procedures and database behavior so the business could keep operating and regain system understanding.

5. Vision3

   Jun 2008 – Dec 2014

   Software Engineer - iOS / .NET / Flash / Unity3D

   • Built interactive applications spanning Objective-C/iOS, C#/.NET, Flash/ActionScript, Unity3D, REST APIs, sockets, gesture input, touchscreen installations, and real-time 3D model manipulation.

   • Partnered closely with designers to turn visual concepts into polished interactive experiences for clients including Delta Faucet, NCAA, Raytheon, Medtronic, DePuy, Rolls-Royce, and Firestone Building Products; also built a CMS for larrythecableguy.com.
