Most organizations already have Microsoft 365. What they often don't have is a well-structured system behind the way work actually gets done. That usually shows up as approvals running through email, processes living in spreadsheets, documents without proper version control, and teams spending time on work that should largely run itself. That's typically where I get involved. I work with organizations to design and build Microsoft 365 solutions that bring proper structure to internal operations - built on SharePoint, Power Apps, Power Automate, and Power BI. I've been doing this for over 10+ years, working with organizations across the UK and Europe - operational teams, regulated environments, enterprise business functions. The work spans SharePoint Online, SharePoint On-Premises, and the Power Platform depending on what the situation calls for. The kind of work I do most: Building Power Apps that replace spreadsheet-based processes with proper business applications. Designing approval workflows in Power Automate with clean routing logic, escalation handling, and audit trails. Setting up SharePoint environments that are structured for the long term - right permissions, right architecture, right governance from the start. Building Power BI dashboards that give operational teams actual visibility into what's happening. Delivering document management systems where documents go through proper lifecycle stages before they're published. Setting up SharePoint intranets and employee portals that connect properly with Teams and Outlook. Connecting Microsoft 365 to external systems through REST APIs and custom integrations. Building AI-powered automation using AI Builder for things like invoice processing and document data extraction. Projects I'm regularly brought in for include document control and approval systems, procurement and purchase order workflows, capital project authorization, employee onboarding and HR self-service, inspection and compliance management, resource and room booking, operational reporting, and multi-level approval systems across Finance, Operations, and Executive functions. I don't typically get involved in single-task work. Most of the time a business process has grown beyond what email and spreadsheets can handle, or an existing system wasn't built properly and needs rethinking. That's the kind of problem I work on. The way I approach it is practical and architecture-led - clean data structures, maintainable logic, clear permissions, and a solution that the business can actually manage and build on going forward. If that sounds like what you're dealing with, I'm happy to take a look at what you have and talk through what a properly built solution would look like.

I have more than 15 years of programming experience. As a freelancer, I have broad experience: I developed web (ASP.NET, Python, PHP), desktop (C++, C#, Python — Linux and Windows) and mobile (Android — Java, C++) applications. I list here some of my jobs. C#: * clubspeed.com — a large software suite for family entertainment clubs; included C# code (80%), including CoreApi and ASP.NET Razor, plus PHP (Laravel) and Node.js code (for low-level car racing control tasks). I developed it as a team member. * qadra.com — a financial company; C# code (80%), Python (some microservices are Python/Flask based, 20% of code), AWS-hosted with Docker containers and Lambdas. I developed it as a team member. * enven.nl — implemented from scratch their non-public partners portal: ASP.NET Razor and some CoreApi endpoints. * ASP.NET website for house rentals. * ASP.NET website for remote control of a robotic device via a WebSocket connection. * Vegetable-oil plant automation desktop program (C# + WinCC). Python: * Embeddable fact-checking chat that uses the LangGraph framework to implement a customizable LLM/AI backend (OpenAI, DeepSeek, Hugging Face, or Ollama). It allows administrators to embed the component in their websites so users can ask questions about facts described in articles and verify whether facts listed in an article are true. It included agentic code and many external APIs to check facts (not just asking an LLM), and even computer vision to inspect website photos (OpenCV). Backend is FastAPI. * AI/LLM-based ad selection for a website (FastAPI and LangGraph). It processes website text or chat messages and selects ads of different types related to the content. It contains SDKs for embedding ads on many platforms, including Go, React, and plain HTML. * Polish-language training software, based on Django and LangGraph. * Many small projects: desktop scripts, web scraping (Selenium and related tools), and simple AI agents. C++: * Factory equipment monitoring system (Ubuntu Linux, custom server over TCP/IP, web interface in PHP). * Many small projects, some of which are mentioned in reviews on this profile; many are non-public. * Powerful software for automated ad submission on social networks (massive bots that send millions of messages). PHP: * 20+ websites — without CMS, with my own CMS, and with open-source Drupal, WordPress and Joomla CMSs. * Backends for Android applications. Android: * SOCKS5 proxy application that allows sharing mobile VPN with non-mobile clients via the SOCKS protocol. * Many WebView-based "business card" applications. * Dating-related applications, including erotic puzzles. Human emulation: * Spam bots — I cannot provide a specific list of such software for legal reasons. * Automatic checkout on eBay and similar websites. * PayPal automatic payments. * Data scraping, including air tickets and goods in online stores. Reverse engineering — I cannot provide a specific list of reverse-engineered software for legal reasons. * Java bytecode reverse engineering, including Android. * .NET bytecode reverse engineering. * Machine code for 32-bit and 64-bit x86 and ARM CPUs. Assembler: * High-performance cryptographic library for x86\_64 CPUs.
