Software Engineer

I partner with businesses and individuals to bring their digital ideas to life.

Whether you're launching a new venture or scaling an existing one, I can help. Let's discuss your project.

About Me

I'm a software developer who builds impactful digital solutions for fintechs and startups. My expertise lies in taking projects from concept to deployment, creating platforms that not only function flawlessly but also drive business goals.

At EFGH, I built the primary web presence for the company and am part of the team building its flagship product, SMEsure™. My work there went beyond development to include implementing workflow automations and chatbots that significantly improved operational efficiency and user engagement.

Outside of work, I'm an avid runner and reader, always seeking new challenges and perspectives whether I'm on the trail or in the pages of a book.

I'm currently seeking new freelance opportunities to help businesses thrive. If you're looking for a dedicated developer to build your next project, I'd love to hear from you.
