I help businesses replace spreadsheets, Microsoft Access databases, and manual workflows with user friendly software systems, built around how they actually operate. Most of the companies I work with have reached a point where their existing processes are no longer scaling efficiently: -spreadsheets becoming difficult to manage -disconnected tools and duplicated data -too much manual work -lack of visibility into operations -systems that have simply outgrown their original purpose That’s where I come in. I specialize in building operational business systems such as: • CRM / ERP / MRP systems • Inventory and order management systems • Job tracking and workforce systems • Quoting and estimating tools • Dashboards and reporting platforms • Automated workflows and integrations • Microsoft Access to Web App conversions My approach is different from most custom development because I build using a proven, custom framework and architecture refined across dozens of real-world business applications. This allows me to deliver: ✔ Faster development ✔ Lower overall project cost ✔ Reliable and scalable systems ✔ Clean, maintainable code ✔ Consistent workflows and user experience With this approach, you’re not paying to reinvent the wheel - you’re benefiting from systems and patterns that have already been proven in production environments. Before transitioning into software development full-time, I spent 8 years working in engineering and manufacturing in Canada. That experience gives me a strong understanding of operational workflows, process design, and the real-world business challenges behind the software. Today, I have: 🏆 Nearly 100 successfully completed projects on Upwork 🏆 100% Job Success Score maintained for over 8 years 🏆 Extensive experience with complex operational systems and custom workflows I’m also a strong believer in transparency and long-term reliability. -Clear and honest communication throughout projects -Fixed-price projects whenever possible -Strong internal QA/testing process -Lifetime bug-fix guarantee on fixed-rate builds If your current systems are slowing your business down, feel free to reach out. I’m always happy to take a look and discuss possible solutions.
