Thomas
Winter

Lead Software Engineer who takes products from zero to shipped.

I run Forsaeti, a productized ops & build studio. I join teams as a full-stack engineer who owns delivery end to end, from product shape to a shipped, useful result.

Built to ship.
Easy to insert.

I’m a Lead Software Engineer who ships production systems and turns operational bottlenecks into live products.

Through Forsaeti I’ve taken products from idea to shipped, shaping the workflow, building the full-stack system, and delivering client work people can use. AI is part of the toolkit when it serves the product: agents, RAG, LLMs, and local inference.

Before going independent: CNA National (Java/Angular modernization), Infosys (AWS microservices migration), and production leadership at Propagate / Fuse Media. I own the stack: frontend, backend, deploy, and the AI capabilities that support the work.

Clear communication. Honest scoping. No ghost jobs. Insert me into your team or hire the studio. Same operator.

Shipped under
Forsaeti, and by me

Same work deck as the studio: products I shipped, demos I built, and Expo prototypes with honest status labels.

Questionnaire Desk

I designed and shipped the productized desk that drafts SIG Lite / CAIQ / custom security questionnaires from a client evidence pack, so deals don’t die in procurement.

Bid Matrix Desk

RFP → Section L/M/C-style compliance matrix + response outline. I built the offer, the site, and the delivery shape so capture teams get structure without surrendering the bid.
