+SELECTED WORK // PRODUCTION SYSTEMS

Selected systems, measurable impact.

Three products shaped from architecture through operation.

THREE BUILDS / ONE DECK

PRODUCT ENGINEER & BUILDERONE SYSTEM / END TO END

PRODUCT PRACTICE // 04 LAYERS

One product surface. Four systems working together.

I work through the entire product path—from interaction model to data boundaries, AI context, and production performance.

SYSTEM THREAD / ACTIVEFOCUS A LAYER TO INSPECT

01 / INTERFACE

Interfaces people can read at a glance.

Responsive product flows, accessible systems, and a durable component language.

React · Next.js · TypeScript

02 / BACKEND

Rules that stay correct at scale.

Tenant boundaries, RBAC, transactional workflows, and observable APIs.

Node.js · Prisma · PostgreSQL · Redis

03 / APPLIED AI

AI grounded in product context.

Source-aware retrieval, streaming answers, guardrails, and model routing.

LangChain · Gemini · Vector search

04 / PERFORMANCE

Fast paths that survive traffic.

Query plans, caching, indexes, deployment telemetry, and reliable delivery.

SQL · Docker · AWS · CI/CD

ENGINEERING RANGE / FIELD NOTES

Systems, not just screens.

From contextual AI to tenant isolation and the performance work between them.

+ENGINEERING LAB // LIVE SYSTEM STUDIES

The interface is only where the system becomes visible.

Three areas where product craft and engineering depth have to work as one—from useful AI to controlled operations and speed under load.

AI & CONTEXT / WHAT HOLDS UP

Grounded answers from messy knowledge.

Retrieval flows that preserve context, expose sources, and keep model behavior inspectable from document to response.

What needs to move next?

Pick the constraint closest to yours. We can turn it into a clear first move—without a bloated discovery process.

0 → 1 PRODUCT BUILD

Turn a strong product thesis into something people can use.

Shape the smallest credible release, establish the architecture, and ship a production-ready product without burying the next iteration in shortcuts.

FIRST MOVE: A focused product and technical brief
TYPICAL START: 2–4 week first release
