We design and ship production-grade systems: Rust engines, real-time platforms, and AI-assisted products for people who need software that survives contact with reality.
SELECTED WORK
Client work is shown anonymized. The software belongs to them. The engineering is ours.
Hospitality · Brazil · Under NDA
Weekly ops time back. Bookings and expenses land in the books without re-keying.
Problem
An operator running multiple Airbnb properties was losing hours every week to manual revenue tracking, expense spreadsheets, and paper receipts.
Approach
We built a platform that reads booking PDFs and receipts and turns them into clean financial records, so the team stops typing the same data twice.
Digital assets · Under NDA
Strategies are proven before live capital moves, and every rebalance leaves a clean audit trail.
Problem
Rebalancing crypto portfolios by hand is slow, error-prone, and hard to explain after the fact.
Approach
We built an engine that can prove a strategy on history first, then run rebalances with a full trail of what happened and why.
Capital markets
Custom screeners run fully on the operator’s machine. Data stays local.
Problem
Off-the-shelf screeners cannot run custom machine-learning classifiers on local market data.
Approach
We built a local screening tool for crypto and Brazilian equities, with interactive charts and no requirement to send data to a vendor cloud.
Capital markets
Official exchange files become a documented API, with metrics and alerts wired from the start.
Problem
Reliable Brazilian market data is locked behind expensive terminals and inconsistent vendor feeds.
Approach
We built a data platform that takes official exchange files, normalizes them, and exposes a clean documented API other systems can trust, with monitoring from day one.
Computer graphics · Voxel rendering
A voxel rendering core you own: large solid scenes that stay practical to display, less waste in memory and draw cost, and a clear path from volume data to the picture on screen.
Problem
Dense voxel scenes are expensive to render when a general graphics stack treats every solid cell as work, even the ones nobody can see.
Approach
Voxtapen is a computer-graphics render engine for voxels: compact world data on the CPU, only outer surfaces prepared for the GPU, and content from tools teams already use, including MagicaVoxel .vox.
SIGNAL LOG
Attributed by role and sector. Client names stay under NDA.
We stopped drowning in booking PDFs. The books just update, and I got my Sunday back.
Not a black box. Every rebalance is auditable, and the backtest harness paid for itself before we touched live capital.
Local-first was non-negotiable. Custom classifiers on our machine, charts that keep up, no cloud tax.

CAPABILITIES
Rust from first principles: renderers, engines, CLIs. No framework crutches where performance lives.
Full-stack web products, typed end to end and shipped to production, not demos.
LLM pipelines that do real work: document parsing, OCR, classification, with structured output you can trust.
Multiplayer worlds and live data at the edge, with state synced before you notice it moved.
Software that owns its data. Offline-capable, cloud-optional, yours.
The workflows that keep quality non-negotiable: spec-driven development, CI gates, scripted releases.
OPERATORS
Tech Byte Frontier is an independent software house based in Brazil, working remote-first. We lead with engineering (systems, products, and applied AI) and we stay small on purpose so accountability never gets diluted.
Tauan Flores
Founder & Principal Developer
Hands-on on the critical path. No account-manager layer between you and the people writing the code.
PRINCIPLES
Proof over atmosphere
Working software, auditable decisions, and outcomes you can point at. Not theater.
Constraints first
NDA, local-first, latency, budget: we name the hard edges before we estimate.
Ship and stay reachable
Deployed, documented, handed over. We do not vanish the week after launch.
PROCESS
01
A conversation, not a questionnaire. We map the problem, the constraints, and what done means together.
02
You get scope, timeline, and price in writing before anything starts. No open-ended meter running.
03
Short cycles with working software from week one. You review progress as it happens, not at the end.
04
Deployed, documented, handed over. And we stay reachable after launch.
Ready when you are.
FAQ
Discover → Propose → Build → Ship. You get written scope, timeline, and price before build starts. Fixed scope, time & materials, or retainer: matched to the problem, not a one-size product SKU.
Yes. Client work on this site is anonymized by default. We treat code, data, and business context as confidential.
Working software from early cycles. Not a three-month dark period. Exact timelines depend on scope; we put dates in the proposal.
Based in Brazil, remote-first. We collaborate async with clear written artifacts and scheduled syncs when they earn their place.
Rust where systems demand it; TypeScript/React for products; Python for ML harnesses and data work; Postgres and SQLite as default data stores. We pick for the constraint, not for a resume.
We are not a staffing body shop, a pure design agency, or a slide-deck consultancy. If the engagement is mostly meetings with no path to production software, we will say so.
