I derive great pleasure from my work, and solving new challenges is my entertainment. This is why I always make time to learn new technologies. I am a technical developer and system integration analyst, specialized in web and Windows, with strong project analysis capabilities. My 15-year experience in designing office automation and warehouse management systems has given me a strong understanding of the challenges in integrated systems, allowing me to provide solutions that optimize performance and reduce costs. Time is capital for me, and cost for you. I strive to achieve the best outcome from the time I invest in designing or building an application, and this "win-win" approach has been the key to my success over the years. My goal is to understand and comprehend your vision, so that I can turn your dreams into reality, and grow alongside you. I am ready for long-term engagements and will provide the best support for my programs. My expertise lies in developing custom business solutions, desktop applications or web applications, and Windows automation. I am also a product owner, having developed an office automation application and a warehouse management system for public warehouses, which have been continuously improved and upgraded since 2012, alongside my work in designing and building custom web applications. I am proficient in SQL and working with big data. For example, I was once invited to a project where it took around 9 hours to send the information, and I was able to reduce that time to less than 3 minutes by designing specialized SQL queries. My core skills include: โ€ข C# .NET Framework and Windows development โ€ข Warehouse management & ERP system and IoT development โ€ข Integrated business systems design (e.g. accounting, inventory, sales) โ€ข ASP.NET & MVC, ASP.NET Core โ€ข API Integration โ€ข Microsoft SQL Server & PostgreSQL & Database Architecture โ€ข Next.js & Tailwind & Django โ€ข Supabase โ€ข Solutions Architect I am a full-stack developer with 4 years of experience in React and Next.js. While my primary expertise lies in back-end development, I can also efficiently build front-end layouts for applications that do not require complex animations. I have worked with Angular in the past. My commitment to exceeding expectations leads to exceptional final products

As a Fractional CTO, I partner with founders and executive teams to bridge the gap between commercial vision and technical execution. Software and platforms I have architected are currently utilised by organisations including the NHS, Aston Martin, Vodafone, GSK, Experian, National Grid and more. My approach is rooted in firsthand experience across the entire product lifecycle. Before building and scaling my own B2B and B2C SaaS companies as a founder, my background spanned senior development, solution architecture, and UI/UX design. Because I have operated at every level of a tech company, I know what excellent execution looks like, how long it should take, and how to align it directly with your business goals. Today, my focus is entirely on technical leadership and strategy. My engagements typically begin with a deep dive into your business: assessing requirements, analysing data, and defining a clear, actionable roadmap. Once the strategy is signed off, I organise the necessary resources and lead the project through to successful deployment. I am completely flexible in how we execute. I can step in to provide structure and leadership to your existing development team, or I can bring in my own, proven, world class, end-to-end product team. This includes senior developers (ex-Google), cloud infrastructure engineers (ex-Serverpod), Senior UI/UX designers (ex-Dept) who have collectively worked on some of the largest products on the planet (Spotify, Google Firebase, The Claridge's Website).
