Skilled Developer - T-SQL, C#

United Kingdom - Tests: 9

Currently my strongest skills are C# and SQL Server, but I have used a variety of other programming languages and technologies historically, including: VB3-6, Delphi 4&5, VBA, C++, ASP.NET. I started programming over 20 years ago as a teenager and knew immediately it would be my future career. I am comfortable working with (and enjoy) complex problems and feel this is a specific strength of mine. I prioritise and value long term client relationships where I can build understanding of a problem domain over time and provide development expertise and design solutions that maximise my value. I work well independently and consider myself able (upon understanding a problem domain) to both design and implement a solution. I welcome opportunities to expand and develop my knowledge and skills.
