Selected work · Evidence before claims

Inspect the work,
including its limits.

One first-party delivery case and three working technical references. Every item names its role, constraints, decisions, evidence, and claim boundary.

Proof policy

A label is part of the evidence.

  1. 01Internal product

    First-party work where the repository and release artifacts can be inspected.

  2. 02Reference build

    A working technical system using fictional or reviewed project data—not a client result.

  3. 03Client work

    Published only with permission, a precise role, and enough evidence to support the outcome.

01 / Published case studies

Four systems with inspectable decisions.

Incomplete proof remains unpublished. A polished concept never substitutes for a client outcome.

Internal product · Performance & technical SEO

A reversible website migration with every public route accounted for.

Read case
Declared migration path
Before/USA/* After/*
Before/CV/* After/portfolio/*

A first-party build note showing how the commercial Astro site moved from a subdirectory to the canonical root while a separate Next.js portfolio kept its own URL space.

Role
First-party migration planning, Astro implementation, redirect configuration, release-gate checks, browser verification, and technical documentation for the site's own move.

Reference build · Grounded AI & retrieval

A knowledge assistant that shows its evidence—or declines to answer.

Read case
Evidence Desk showing a supported answer beside its exact source and retrieval trace
Working interface with fictional prompts and a reviewed project corpus.

A working bilingual RAG reference that retrieves from a reviewed corpus, returns inspectable citations, exposes its trace, and withholds unsupported answers.

Role
Designed and implemented as a repository-backed reference build, including the Astro interface, same-origin API contract, retrieval and answer service, safe error states, and automated tests.
Evidence
Maximum 2 citations · Source release

Reference build · Controlled workflow automation

A workflow that stops exactly where human judgment begins.

Read case
RelayOps paused for a human decision before a simulated customer follow-up task
Working browser reference with fictional data and no external connection.

A deterministic browser-based reference showing validation, allowed state transitions, explicit approval, idempotent retry behavior, and a visible audit trail.

Role
Designed and implemented as a local reference build, including workflow states, validation branches, approval controls, simulated adapter behavior, audit history, and browser tests.
Evidence
3 visible paths · Scenario coverage

Reference build · Evidence-first document AI

Document extraction where every retained value points back to the source.

Read case
FieldDoc comparing a source delivery note with extracted fields and exact evidence
Working reference using fictional document content; proposed values remain subject to human review.

A working reference for extracting delivery notes and work orders into a closed schema while preserving exact evidence, deterministic checks, and human approval before export.

Role
Designed and implemented as a working reference build, including the Astro review interface, same-origin API contract, closed-schema extraction, server-side evidence validation, deterministic checks, local fallback, and tests.
