// about

15+ Years Building
Production Systems

Full-stack engineer specializing in .NET microservices, React/Angular frontends, and AWS cloud infrastructure. I've shipped IoT data pipelines processing tens of millions of events daily, led SSO and email delivery overhauls, and integrated agentic AI into engineering workflows. I care about reliable systems, clean APIs, and shipping things that actually work in production.

  • Designed high-throughput .NET Core microservices on AWS ECS/EKS ingesting tens of millions of IoT meter-reading events daily via async pipelines, SQS/SNS, and REST APIs.
  • Built complex, reusable Angular/React components — consumption charts (Chart.js), a timeline editor for IoT device scheduling, multi-select data grids, and KPI cards.
  • Architected a provider-agnostic SSO system enabling runtime-selectable identity providers for the Neptune360 platform.
  • Led email delivery pipeline overhaul (Sendinblue integration) improving deliverability from 95% → 99% and eliminating legacy infrastructure.
  • Integrated agentic AI (Claude Code, GitHub Copilot) into team workflows, accelerating delivery and enabling rapid prototyping of complex features.
  • Owned CI/CD pipelines (Jenkins), production monitoring (CloudWatch), and mentored junior engineers on async patterns and cloud architecture.

Email Deliverability Improvement

After leading the Sendinblue integration at Neptune, deliverability climbed from 95% to 99% and stabilized — eliminating legacy bounce issues.

Personal Projects & Interests

🤖

Local LLM Stack

Self-hosted Qwen3 via Ollama + Open WebUI running in Docker — full privacy, zero cloud dependency. The same pattern I use to evaluate AI tooling before recommending it for production.

🏎️

Motorsports / HPDE

Qualified for HPDE blue group after just two sessions — the track teaches you to be precise, calm under pressure, and to trust your systems. Translates directly to production engineering.

🎾

Racquet Sports

Tennis, pickleball, ping-pong — competitive by nature and always looking for a good match.

🎓

Emory University

BA in Economics — strong analytical foundation. Also holds Microsoft certifications in C# and ASP.NET MVC 4.
