Matunos Prototyping Lab

Digital Tools &
Financial Prototyping.

We build specialized internal utility applications and high-fidelity prototypes that bridge the gap between financial models and production software.

Android Lab

An active Android lab, with Focus Vault live on Google Play. Client apps are prototyped with the client throughout development: a working build on your own phone early, refined together at every stage. We utilize Kotlin Multiplatform where appropriate to ensure code consistency.

Financial Logic

Translating complex financial models into high-performance software. We specialize in Pricing Engines, Risk Analyzers, and Portfolio Trackers.

React & Cloud

Full-stack web applications built on React and AWS/GCP. Scaleable, secure, and designed with a "Mobile-First" philosophy.

The Matunos Software Development Lifecycle

Building custom software for the financial sector requires a different level of rigor. At Matunos, we don't just "write apps"—we engineer financial instruments. Our development philosophy is rooted in quantitative research and technical heritage, ensuring that the logic behind every click is mathematically sound.

Android Development: Our Android lab is active: our first app, Focus Vault, is live on Google Play, and more are in development. For client work, prototyping is part of the build rather than a phase before it — you hold a working version on your own phone early, and we refine it together as development goes on, prioritizing performance, security, and exceptional user experience. We utilize Kotlin Multiplatform where appropriate to ensure code consistency across systems while maintaining native performance.

Financial Prototyping: Many of our clients come to us with a spreadsheet or a mathematical model and say, "I need this to be a tool for my team." We bridge that gap. We specialize in taking the complex "maths in the background" and wrapping it in a professional, high-performance interface that your team can actually use. This often involves integrating with AI & Automation engines to handle data input more efficiently.

Security-First Coding: Every line of code we write undergoes rigorous security auditing. In the banking world, a memory leak isn't just a bug—it's a vulnerability. We employ static and dynamic analysis tools throughout our CI/CD pipeline to ensure that your custom software is resilient against modern attack vectors.

Heritage Portfolio

Foundational Engineering Projects

Time Series Forecasting Interface

Time Series Forecasting (TWP)

Development of specialized software to identify and forecast financial time series using ARIMA procedures. This was specifically applied to forecasting FX rates associated with multi-year corporate capital expenditure (CAPEX) planning.

  • Matlab
  • ARIMA Modeling
Convertible Bond Valuation Engine

Convertible Bond Valuation Engine

Implementation of the Tsiveriotis & Fernandes model. A high-performance engine that mapped 3D valuation surfaces and analyzed residuals against empirical data. This project was a cornerstone of our quantitative research.

  • Financial Engineering
  • 3D Mapping
CompareFox Reconciliation Tool Interface

CompareFox

A lightweight reconciliation tool used to reconcile file-system based files from two different directories. It serves as an essential accelerator during system migrations and regression testing, providing rapid verification of massive data sets with pinpoint accuracy.

  • C# / .NET Utility
  • Reconciliation Accelerator

"Our heritage in quantitative research means we don't just build software that works—we build software that is right."

AutoExpenseZA

Local-First Digital Expense Tracker

An incredibly streamlined, high-security mobile prototype built exclusively for professional teams needing absolute privacy. AutoExpenseZA represents our thesis on local-first client architecture for highly corporate user bases, removing centralized risk nodes altogether.

Core Functional Milestones
Local Processing & Verification

Captures paper receipts natively, automatically reading data locally on device without sending sensitive documents to cloud-hosted APIs.

Advanced Local Storage Compression

Optimized image reduction and fast byte compression structures compress and archive files directly in the document directory to protect scarce mobile disk space.

Pure Air-gapped Privacy

Zero internet connectivity required. The application works offline on secure localized nodes, ensuring zero data leakage to public servers.

Multi-Currency & Instant Export

Processes diverse multi-currency portfolios seamlessly, packs monthly batches into locked ZIP files, and exports customized PDF accounting ledger sheets.
