Software engineer & technical lead
I build software
that people can count on.
I'm Alex, a software engineer and technical lead at the U.S. Department of the Treasury. I build AI-integrated applications from architecture through deployment, and maintain SpeechKit, an open-source speech and language toolkit for Obsidian.
01 / OPEN-SOURCE WORK
Creator & maintainer
SpeechKit
SpeechKit brings live dictation, meeting transcription, local translation, and natural read-aloud into the editor where people already keep their notes.
I built SpeechKit so recording, transcribing, translating, and listening could happen in one place—with shared controls and model management inside Obsidian.

SpeechKit works locally once its models are installed—no account, telemetry, or required cloud service. Optional LLM tools stay separate and use only a provider the person chooses.
Under the hood: a TypeScript Obsidian plugin, Rust native sidecar, and model support across macOS, Windows, and Linux.

AI Engineer / Technical Lead
Leading end-to-end delivery of AI-integrated applications.
As technical lead, I own product architecture, implementation, cloud infrastructure, and delivery. I work with division leadership to turn organizational priorities into secure, reliable software.
Re-architected a brittle service, shortened automated test feedback from roughly 40 minutes to two, and introduced continuous deployment.
Architecture, reliability, and delivery
I design API-first services and Terraform-managed infrastructure, with validated AI outputs, fault recovery, and safeguards against denial-of-service and model-cost abuse.
I also remediated critical and high-severity infrastructure and dependency findings as part of the rebuild.

Junior Software Engineer
Making everyday HR operations easier.
I was the sole maintainer of core HR applications, responsible for releases, feature development, and Workday synchronization support.
A data-import API I built recovered approximately 15 hours per week across four team members. An administration dashboard replaced ad-hoc SQL corrections and reduced HR data-correction time by 80%.

03 / HOW I WORK
Strong fundamentals.
Faster delivery.
I define what the product should do, how it should behave when things go wrong, and what doesn't belong in scope. Then I use Codex and Claude Code to accelerate implementation—and review the result as a complete system.
I keep that speed sustainable with reliable tests, straightforward deployment, and systems that are easy to understand and change. Review stays proportionate to the risk.
