Experience

Freelance frontend developer — Independent client work

Remote

2019

Built several paid frontend prototypes for an online client, including product and catalogue interfaces for mobile-accessory and spirits businesses.

Developed responsive interfaces using Angular, TypeScript, JavaScript, HTML, and CSS.
Implemented client-side routing, reusable components and services, catalogue loading and filtering, and shopping-cart interactions.

Upholsterer — Family business

Complete customer upholstery jobs in a small family-run business, solving practical problems and carrying work from requirements through delivery.

Perform hands-on production work, resolve practical job-specific problems, and help carry customer work through completion.

Independent engineering projects

Orbiter — NES emulator and introspective debugger

C / Win32 / D3D11

2024-present

Evolved a multi-year NES emulator project into a Windows debugger with live disassembly, hardware inspection, execution tracing, profiling, control-flow hit counts, breakpoints, and deterministic rewind.
Separated emulator execution, debugger state, and the D3D11 interface behind explicit APIs, with automated snapshot-restore and determinism tests.

LeakCheck — Deployed revenue-reconciliation prototype

JavaScript / SvelteKit / PostgreSQL / Vercel

2026

Built and deployed a full-stack learning prototype that reconciles completed CRM jobs with accounting invoices and produces traceable revenue-risk findings.
Used the project to develop foundational knowledge of SvelteKit, PostgreSQL schemas and queries, REST/JSON data flow, dataset validation, and deployment.

Android interface libraries — Published Android graphics libraries

Java / Kotlin / Android / JitPack

2019-2022

Published a configurable superellipse renderer through JitPack (37 GitHub stars and 9 forks) and built a Kotlin audio-visualization library with capture, parsing, scheduling, and renderer layers.

elf — Embeddable C-like scripting language

C / Compiler / Bytecode VM

2023-present

Designed and implemented a lexer, source-located AST, IR lowering, bytecode backend, slot-based VM, closures, garbage collection, and a native C API.
Created a contiguous table model with open-addressed key-to-index bindings; elf runs real Bob build descriptions and Orbiter configuration.

Bob — Programmable incremental build system

C / elf / BLAKE3

2026-present

Built a dependency-graph scheduler with parallel task execution, compiler-discovered dependencies, BLAKE3 fingerprints, persistent incremental state, and explainable rebuild decisions.

Apollo — From-scratch Windows text editor

C / Win32 / D3D11

2026-present

Built file-backed buffers, multi-cursor editing, fuzzy search, custom font rasterization, and a purpose-built D3D11 interface.
