Everything that gets built.

Your internal processes deserve better than a shared Excel or a SaaS tool that only fits 70%. I design and build the app that fits your workflow exactly: information distribution, multi-system orchestration, business integration. Stack designed for long-term maintainability — C#/.NET primarily, with what fits the context around it (Python for data, Go for network services, etc.).

When a system slows down, scales poorly, or costs too much, it's rarely because you need to "rewrite in Rust". It's almost always 3-4 hotspots identifiable with a profiler, architecture choices to fix, or SQL queries to rework. I come in, measure, identify, propose a costed plan with expected impact. Then we execute — or you do it in-house with the plan.

Need a website? Benefit from Fluid's experience, powered by Laravel, to enjoy a fast, powerful website with an aesthetic tailored to your tastes and requirements.

When Notion/Airtable isn't enough and a generic SaaS costs 200€/month for 10% of what you need, time to build your own. Default stack: Laravel + Filament for powerful admin panels in days, Tailwind for the front when you need more than a back-office. No useless SPA, no gratuitous complexity — just what's needed to work, be maintainable, and let you take over if needed.

Generic ChatGPT doesn't know your processes, your contracts, or your code. RAG (Retrieval-Augmented Generation) does. It's the layer that lets an LLM answer based on your data: internal knowledge base, technical docs, client contracts, codebase. I design and integrate the full chain — embeddings, vector store, prompt engineering, guardrails. Output: a useful assistant, not a hallucinating parrot.

For cases where managed runtime is no longer an option: embedded, drivers, real-time code, low-level communication. I work in C, C++, Rust and native C# when relevant. Whether it's a microcontroller firmware, a Windows/Linux driver, a kernel module or a service with hard memory/perf constraints — you have someone who speaks to the metal without throwing layers of abstraction on top.

You have a codebase that's scary to touch, a project inherited from a previous dev, or a tech decision to make without the perspective to choose? That's what an audit is for: I spend a few days in your code, your diagrams, your metrics. I come out with an actionable report — not an 80-page PDF that ends up in a drawer. Clear scope, costed remediation plan, prioritized for your business context.

You inherited a binary without sources, need to understand a proprietary protocol, analyze a malware or recover the logic of an app abandoned by its vendor? That's what reverse engineering is for: disassemble, understand, document. I work on Windows and Linux, primary focus on .NET binaries (IL/CIL) and native x86/x64/ARM. Output: usable technical doc + recommendations.
