Systems-first mindset
Mapping database schemas, validation requirements, and failure modes prior to frontend execution.
Available for Work
Designing robust systems before writing UI code
Web architecture, backend foundations, performance-aware interfaces, and AI-integrated products built with clean engineering judgment.

About
Software achieves its purpose when the architecture behind it is as deliberate as the user experience. I design systems from the data layer up—planning validation schemas, API boundaries, and real-time state before laying down a single line of layout.
My core competency lies in backend-intensive full-stack engineering. By combining Node.js, PostgreSQL, and MongoDB with LLM integration pipelines, I build applications that process complex structured data and synchronize real-time updates. Clean judgment means balancing efficient data delivery with fast, responsive frontend states.

Mapping database schemas, validation requirements, and failure modes prior to frontend execution.
Bridging complex user interface state with structured, type-safe API communication patterns.
Architecting secure authentications, real-time WebSockets, and predictable REST API contracts.
Applying validation guardrails and structured generation patterns to yield deterministic LLM outputs.
Process
01
Analyze constraints, define state flows, and establish core data-handling requirements before writing code.
02
Architect database schemas, detail JSON API contracts, and draft resilient failure-recovery states.
03
Implement clean vertical slices, ensuring component modularity on the frontend and strict data validation on the backend.
04
Validate production builds, secure environment variables, and release continuously via automated Vercel pipelines.

Projects

A production-oriented, AI-powered learning workspace designed to outclass generic chat interfaces. Engineered with a Persistent Learner Memory Engine, RAG grounding on student materials via pgvector, an independent Verification Audit layer, and an empirical Outcome Data Flywheel to dynamically optimize teaching strategies.
Completed AI learning assistant that uses Socratic questioning, guided chat, and saved learning sessions to help learners reason through concepts.

Autonomous GitHub PR security & code review agent built on an empirical tool-calling loop (AST static linter, OSV.dev vulnerability scanner, unit test runner). Generates 1-click inline PR patches with multi-tier LLM fallback and real-time dashboard observability.
