StrategyDesignEngineering

Tailor-made digital solutions.

I design and build digital products end to end, from architecture and data to backend systems and interfaces, turning real problems into software that works.

What I Build.

End-to-end software development, from planning to delivery.

  1. 01

    Product Engineering

    Understanding the business rules, deciding what to build and carrying it through to the people who use it.

  2. 02

    Backend & APIs

    Services and APIs that hold the business rules, with clear contracts between the parts of the system.

  3. 03

    Integrations & Automation

    Connecting systems and external services, and turning manual operational steps into automated flows.

  4. 04

    Data & Architecture

    Data modeling and a clear split of responsibilities, so every new rule has a place to live.

  5. 05

    Product Interfaces

    Screens designed alongside the system's behavior: flows, states and information where people need them.

  6. 06

    Applied AI & Workflows

    Language models and agents applied to concrete tasks, such as triage and support.

03About & Philosophy

Good software is clear, well-structured, and built to last.

I work as a Software Engineer across the full product path, from architecture and data to backend systems, integrations and interfaces. Before choosing technology, I focus on understanding the problem, its rules and what the product needs to support.

At BIGA Codes, engineering, product and design are part of the same build. That intersection is where real needs become software that solves the problem without losing clarity for the people who use or maintain it.

  1. 01

    Clarity

    Code, interfaces and decisions that can be understood without guesswork.

  2. 02

    Structure

    Architecture and data organized so the product can evolve without losing coherence.

  3. 03

    Purpose

    Every technology and detail exists to solve something concrete.

04Lab

Where I experiment.

Experiments, prototypes and research used to investigate technical and product ideas.

RHYTHMIX

TRANSCRIPTION RESEARCH01 / 03

Research behind RHYTHMIX: stem separation, audio analysis and experimental no-reference transcription models, working with MusicXML, MIDI and synchronization. The product in Projects starts from references.

05Let's Work Together

Have something to build?

A new product, an integration or a system that needs improving: tell me about the problem and its context. From there, we work out what makes sense to build and what the next step is.
