Hiring a senior or staff engineer? Let's talk.

Senior or Staff IC, full-time through an employer of record or on a long-term contract. I'm in Santo Domingo (UTC−4), with full US Eastern overlap. Email is fastest: include the role, the stack and the constraint you're working against, and I'll reply within 24 hours.

Good fit

+Senior or Staff IC work on .NET / Angular platforms in payments, fintech or banking.
+Applied AI: on-prem LLM gateways, RAG, agent orchestration under real compliance constraints.
+Systems-adjacent problems — runtimes, performance, protocol work — where reading the C matters.
+Teams that want payment and banking integrations done once, properly.

Probably not

−Pure frontend feature work with no systems or architecture surface.
−On-site-only roles outside US, EU and LATAM time zones.
−Projects where "move fast" means skipping the audit trail in a regulated environment.

Posts to /api/contact on this same C server — the handler validates the body, calls Resend over HTTPS via libcurl, and reports the round-trip back here. No CRM, no autoresponder.
