Business Systems & Internal Tools | C#/.NET, Notion, Automation
Hi, I’m Patrik — a mechatronics engineer and business systems developer. I build internal tools, workflow automation systems and operational workspaces for companies that want to reduce manual work, avoid errors, improve reporting, and make their processes easier to run. My work sits between software development, business operations, engineering workflows and real users. Depending on the project, this can mean a custom C#/.NET desktop application, a reporting automation tool, an Excel/SharePoint integration, a Notion-based operations system, or an automation layer connecting multiple tools together. I’m especially useful when the problem is not just “build an app” or “set up a workspace”, but understanding the workflow, structuring the data, reducing manual steps, and creating a reliable system people can actually use. What I Build • Custom internal Windows tools in C#/.NET, WPF and WinForms • Business workflow automation with Excel, SharePoint, APIs and databases • Notion and Airtable operating systems for teams • Reporting tools and document generation workflows • BOM/rule-based calculation and export systems • Production, lab and engineering workflow software • Barcode/scanner-assisted workflows and data validation • Dashboards, CRM systems, project hubs and operational databases • PDF, Word and Excel export tools • Legacy internal tool improvements and modernization Relevant Background I’m a mechatronics engineer by background, with experience in software, hardware-related workflows, product development, systems architecture and business process design. At Bosch, I worked for around 3 years on software and hardware systems for testing and calibrating inertial sensors. The work started in laboratory test environments and later moved into production-related calibration and validation workflows once the concepts were proven. These tools were used by technicians in real test and production workflows, where reliability, clear UI, correct data handling and reducing operator mistakes were important. In one product case, the related process improvements contributed to increasing production yield from around 68% to 91%. I have also worked on several related internal tools and automation projects, including: • Electronics lab automation software for high-power LED luminaire testing using TCP and SCPI communication • GUI tools for configuring, tracking and managing measurement workflows • Seismo-acoustic sensor data processing and visualization software • Rule-based Environmental Product Declaration report generation from BOM and product data • Excel, SharePoint and server-based data automation • Notion-based business operating systems, CRM structures, dashboards and project management workflows Business & Systems Experience Beyond development, I also have experience in product development, system architecture and project coordination. I have worked in engineering environments where software, hardware, testing, documentation and business requirements had to fit together. I also have a business development background, which helps me approach projects not only from a technical point of view, but also from the perspective of workflow efficiency, user adoption, operational clarity and business value. This is especially useful for internal tools and business systems, where the goal is not just to create software, but to make the actual process faster, clearer and more reliable. Tech & Tools C# • .NET • WPF • WinForms • Python • Lua • SQL • SQLite • Excel • SharePoint • Microsoft Graph API • TCP/IP • SCPI • Serial/COM • Notion • Airtable • n8n • Make • Zapier • Google Sheets • PDF/Word/Excel generation My Approach I don’t just build screens, pages or isolated automations. I first try to understand the real workflow, the users, the data structure and the constraints around the process. Every system should be: • practical for the people using it • structured around real business or production logic • reliable enough for daily internal use • easy to maintain and improve • clear enough that the team can actually adopt it Ideal Projects • Improving an existing internal Windows application • Building a custom desktop tool for production, testing or reporting • Automating Excel, SharePoint or database-driven workflows • Creating a Notion CRM, project hub or business operating system • Turning manual reporting into a rule-based export process • Connecting forms, databases, files, dashboards and automations • Modernizing a legacy internal tool without unnecessary complexity • Building tools that help operators, engineers, managers or sales teams work with cleaner data and fewer manual steps If you have a messy internal workflow, a spreadsheet-heavy process, an underused Notion workspace, or an old internal tool that needs to become more reliable and usable, I can help turn it into a structured system.
