TECH BYTE FRONTIER — INDEPENDENT SOFTWARE HOUSE

SOFTWARE,
ENGINEERED AT
THE FRONTIER_

We design and ship production-grade systems — Rust engines, real-time platforms, AI-assisted products — for people who need software that survives contact with reality.

001//SELECTED WORK

Problems we were handed. Systems we handed back.

Client work is shown anonymized — the software belongs to them. The engineering is ours.

SPEC_001.LOGHOSPITALITY / BR — UNDER NDA

Short-Term Rental Operations Platform

PROBLEM

An operator running multiple Airbnb properties was losing hours every week to manual revenue tracking, expense spreadsheets, and paper receipts.

APPROACH

Full-stack platform with LLM-powered document parsing — booking PDFs and receipts become structured financial records automatically, no manual entry.

STACK

React 19 · Hono · Supabase · Claude API · Fly.io

STATUS

IN BETA

SPEC_002.LOGDIGITAL ASSETS — UNDER NDA

Portfolio Rebalancing Engine

PROBLEM

Rebalancing crypto portfolios by hand is slow, error-prone, and impossible to audit after the fact.

APPROACH

Rust execution engine with an admin CLI, plus a Python backtest harness that validates strategies against historical data before they touch real funds.

STACK

Rust · Python · Postgres · Docker

STATUS

DELIVERED

SPEC_003.LOGCAPITAL MARKETS

Market Screening Terminal

PROBLEM

Off-the-shelf screeners can’t run custom ML classifiers over local market data.

APPROACH

Local-first terminal applying Lorentzian (KNN) classification to crypto and Brazilian equity feeds, with interactive charting and zero cloud dependency.

STACK

FastAPI · React · lightweight-charts · Rust

STATUS

ACTIVE USE

SPEC_004.LOGCAPITAL MARKETS

Brazilian Equities Data API

PROBLEM

Reliable Brazilian market data is locked behind expensive terminals and inconsistent vendor APIs.

APPROACH

Rust data platform that ingests official exchange files, normalizes them into Postgres, and serves a documented OpenAPI — with Prometheus observability from day one.

STACK

Rust · axum · SQLx · Postgres · OpenAPI

STATUS

IN DEVELOPMENT

002//CAPABILITIES

Full-stack in the literal sense.

C-01

Systems Engineering

Rust from first principles: renderers, engines, CLIs. No framework crutches where performance lives.

rust · wgpu · data-oriented

C-02

Product Engineering

Full-stack web products, typed end to end and shipped to production — not demos.

react · typescript · hono · supabase

C-03

Applied AI

LLM pipelines that do real work: document parsing, OCR, classification — with structured output you can trust.

claude api · structured output · evals

C-04

Real-Time Systems

Multiplayer worlds and live data at the edge, with state synced before you notice it moved.

spacetimedb · websockets

C-05

Desktop & Local-First

Software that owns its data. Offline-capable, cloud-optional, yours.

tauri · sqlite · offline-first

C-06

DevEx & Tooling

The workflows that keep quality non-negotiable: spec-driven development, CI gates, scripted releases.

sdd · ci gates · release automation

003//THE LAB

Where we sharpen the edge.

Self-funded R&D. Our own IP, built in the open where possible.

++++

LAB_01

VOX-TAPEN

VOXEL ENGINE

A voxel renderer and engine foundation built from first principles in Rust — no general-purpose engine stack. World state stays compact on the CPU; the GPU receives only surfaces.

++++

LAB_02

FENROK ONLINE

TERMINAL MMO

A terminal-based MMO inspired by Ragnarok Online and Tibia. Rust client, SpacetimeDB backend — a whole world in 80×24 characters. Public devlog available.

++++

LAB_03

SPACEVOX

FEASIBILITY PROBE

Modular ship construction in voxel space — a Bevy prototype testing whether the idea survives contact with the GPU.

004//PROCESS

No black box. No surprises.

01

DISCOVER

A conversation, not a questionnaire. We map the problem, the constraints, and what done means — together.

02

PROPOSE

You get scope, timeline, and price in writing before anything starts. No open-ended meter running.

03

BUILD

Short cycles with working software from week one. You review progress as it happens, not at the end.

04

SHIP

Deployed, documented, handed over. And we stay reachable after launch.

005//CONTACT

OPEN A CHANNEL.

A system that needs building, or one that needs rescuing — transmit the brief.
