Developer & Team Leader | Visual Basic | C# | SQL Server | .NET 10 | .NET Aspire | Blazor | Microservices | MAUI | Blazor Hybrid | Almost 4 Decades of Expertise (Since 1988)
I'm a seasoned Developer and Team Leader with a passion for crafting innovative solutions. Since embarking on my software development journey in 1988, I've navigated the dynamic tech landscape, consistently delivering excellence through a diverse range of projects.
Professional Journey:
Beginning with COBOL, MS Basic and some obscure languages until the mid 90s, then moving into Visual Basic (VB) in 1994, I've witnessed the evolution of this language and seamlessly transitioned into harnessing its capabilities to create robust and scalable applications. Over the years, I've expanded my skill set to include C#, becoming a stalwart in modern software development. My skills however are not limited to these 2 languages.
Team Leadership:
As a seasoned Team Leader, I've successfully led development teams, fostering a collaborative and innovative environment. My leadership style emphasises mentorship, enabling team members to reach their full potential. Together, we've delivered successful projects, meeting and exceeding client expectations.
Technical Proficiency:
WinForms: This is where my journey took me in about 1994 when I started coding in Visual Basic. I wrote an early pay off system for Thorn EMI's finance team in VB v1, while I was working on making the Rent-A-Center system usable in the UK and fix some of the bugs. I have continued to write WinForms applications ever since, in VB.NET and C#.
WPF/Silverlight: WPF seemed to be the natural progression from WinForms, but the 2 couldn't be more different. I have worked with WPF and moved into Silverlight at a later date. I have written many applications in both technologies for many companies, large and small.
SQL Server: Proficient in database design and management, my expertise in SQL Server has been pivotal in crafting efficient and secure data solutions.
Blazor: Pioneering in web development, using Blazor to create dynamic and interactive web applications, seamlessly integrating C# into the modern web.
MAUI: At the forefront of cross-platform mobile development, I leverage MAUI and MAUI Hybrid to craft native applications for diverse platforms, ensuring a consistent user experience.
Azure Functions: Testing in Docker on the local machine and deploying to Azure.
Career Highlights:
Led development teams to successfully deliver projects across industries, contributing significantly to client success.
Recognised for creating scalable and maintainable codebases, providing enduring solutions.
Actively engaged in continuous learning and mentorship, cultivating a collaborative and knowledge-sharing environment.
Let's Connect:
I am eager to connect with fellow professionals, clients, and industry enthusiasts. Whether you seek a seasoned developer or a dynamic team leader for your projects, let's connect and explore how I can contribute to your success.
Looking forward to building meaningful connections and contributing to the dynamic world of software development!
