Portrait of Graham Santana

How I work

Over 3 years of in-company experience, one simple goal: products that hold up in production — not just in a demo.

  • A complete project

    From the specifications to launch, I take your project from start to finish: websites, data back-ends, SaaS, platforms and mobile apps, already delivered to clients.

  • A direct contact

    You talk directly to the person who writes the code, with no middleman, and the work is done with the rigour of two master's degrees in computer science.

  • Code I fully master

    I learned the trade before AI came along: I understand every line I deliver. Today I use it as one professional tool among others, to go faster, while keeping control of the architecture, the security and the quality of the code.

Memory, assembly, networking, shell, emulator, 3D engine: projects written from scratch, as close to the machine as it gets. Click a project to see its code.

CMemory management

Memory allocator

My own malloc / free / calloc / realloc, built as a shared library that replaces the system's. Best-fit search, splitting and merging of free blocks, heap grown page by page.
