I modernize systems that cannot afford to stay fragile.
I design and deliver secure, observable, maintainable software for organizations that cannot afford fragile architecture. I'm strongest when the system is important, the history is messy, and the team needs a path forward - turning delivery pressure into scoped APIs, safer data flows, reusable interface patterns, observable workflows, and enough documentation that the next team is not doomed.

TXN/02Hiring fitverified · OK
Where I can help immediately.
A strong fit for architecture, modernization, technical leadership, and frontend platform roles where the work needs more than clean code - the judgment to reduce risk, the hands-on ability to ship, and the communication to keep executives, engineers, auditors, product owners, and vendors aligned.
Legacy modernization architect
Move monolithic .NET, ASP.NET, VB.NET, SQL, and hard-coded UI flows toward scoped APIs, modular services, safer data contracts, and maintainable release paths.
Frontend systems lead
Turn scattered UI work into reusable Vue, TypeScript, design system, accessibility, and state management patterns teams can actually maintain.
Regulated platform builder
Work inside finance, government, compliance, RBAC, audit, logging, and data governance constraints without turning delivery into paperwork theater.
Delivery rescue & leadership
Step into messy projects, clarify the tradeoffs, reset the architecture path, mentor the team, and keep stakeholders grounded in what will actually ship.
AI accountability systems
Design AI-oriented workflows that leave receipts: inputs, outputs, transitions, validation, logs, and enough context to review or replay decisions.
Cloud-ready delivery
Connect architecture to deployment reality: CI/CD, environment parity, API boundaries, observability, and production-safe static or cloud-hosted delivery.

TXN/08Architecture principlesverified · OK
Fewer fragile surfaces. More verifiable systems.
PR/01
Least exposure
Expose only what the actor, page, role, or process needs. Scope APIs. Shape projections. Treat every interface as a risk boundary.
PR/02
Receipts beat vibes
Important systems should leave evidence: inputs, outputs, transitions, validation, logs, and enough context to replay or explain what happened later.
PR/03
Wrap before you rip
Legacy systems rarely get replaced in one heroic rewrite. Use adapters, contracts, and strangler patterns so teams ship safely while the old system is reduced.
PR/04
Canonical anchor, many projections
Keep one durable source of truth, then derive role-specific, page-specific, and workflow-specific views.
PR/05
Accessibility is architecture
Accessible systems are clearer state, clearer focus, better semantics, better failure modes, and more people able to use the work.
PR/06
The room matters
Good architecture dies if nobody understands it. Translate tradeoffs for executives, engineers, designers, product owners, auditors, and vendors.
TXN/09Technical stackverified · OK
Full-stack, strongest at the seams.
The value is not just knowing tools - it's knowing how frontend state, backend contracts, data models, deployment, governance, observability, security, accessibility, and people all interact.
