I build the proofs of concept that tell a client whether off-the-shelf models can do the job before they commit to building it. One previews cosmetic surgery on a face photo with several image-editing models, using landmark masks so the edit stays on the treated area and ArcFace to check the person still looks like themselves. Another compared image models and LLMs for illustrating and writing social stories for autistic children, with every result shown in the report, failures included.
Lead engineer on an Alzheimer's care platform on AWS, where 200+ caregivers and patients message each other and share care plans. I folded three web and mobile codebases into one TypeScript monorepo and did the security work (encryption, audit logs, access control) that got us through an outside HIPAA readiness review with no critical findings. The ML features were mine too: a decline-risk model and an NLP pipeline for clinical notes. I also mentored two junior engineers.
Moved an old ASP.NET Web Forms real-estate analytics app to Blazor WebAssembly, and pages got about twice as fast. I built the live pricing feed (SignalR plus SQL Server change tracking) that pushed updates to hundreds of users in under a second, along with the component library all the dashboards were built from. The valuation and forecast models behind those dashboards retrained every night on the day's transactions.
Wrote the C# software that ran a self-service food kiosk and a robotic cashier, payment terminal and hardware protocols included. I also built the customer ordering app (Xamarin) and the admin dashboard (ASP.NET Core and Angular). A hardware abstraction layer let the same code run on all three machine models, and orders went to the right kitchen station automatically.
Built multiplayer networking, spatial audio, hand tracking, and the in-world UI for a VR smart-city simulation in Unity, plus a desktop client for anyone without a headset. Scene builds used to take hours of hands-on work. After I automated the art pipeline (model import, LODs, light baking), an artist could start one and walk away.
