Senior Full-Stack Engineer
I turn ambiguous business requirements into configurable, auditable, and long-evolving production systems. Recently shipped jobsignal.dev — a production-grade multi-agent LLM pipeline controlled by schema validation and eval gates.

Why Work With Me
0→1 Production Systems
Build internal admin configurations and multi-tenant commerce platforms that run long-term without constant engineering overhead, featuring automated B-end financial reconciliation.
AI Pipelines with Quality Gates
jobsignal.dev ships a multi-agent LLM pipeline with schema validation, verifiers, and golden-set eval gates (93% → 97.3%). I focus on measurable output quality, not demo hype.
Async-First Autonomy
Fully capable of driving the entire lifecycle independently, from problem definition and tech specs to deployment, ensuring high reliability across time zones.
How I Contribute
Define Boundaries First
Active boundary discovery: I don't just cut scope. I proactively patch incomplete PRDs — mapping edge cases, failure recovery paths, and user loops before writing a single line of code.
Config-Driven Architecture
Config & audit over hardcoding: build multi-tenant isolation, shared RBAC, and interface contracts early to ensure systems are easy to operate, secure, and ready for progressive modernization without freezing the business.
Deterministic Verification
Rigorous verification gates: automated reconciliation and integration tests for traditional backends; schema validators, verifiers, and golden-set PR regression gates for LLM applications.
