I mentor programmers and development teams. I have the skill set to get you out of any development problem. That includes but not limited to: Java, C#, .NET, JavaScript, TypeScript, Python, Spring, Angular, React, and Agile methodologies. I have a focus on writing "clean code", secure coding, and identity management (SAML 2.0 & OAuth 2.0).
I am an experienced, committed software engineer who continually seeks clean, elegant solutions to business challenges. My lifelong passion for technology drives me to proactively expand my horizons, constantly exploring and evaluating new languages, platforms, frameworks, tools, and best practices and applying them in my work to produce truly awesome results.
I also believe that a fundamental prerequisite of highly successful teams is the open, honest interchange of ideas, feedback, and experience, culminating in an environment of personal and professional growth for all involved. It is in this spirit that I offer to share my experience with others as a CodeMentor.
**If I can't solve your problem, you'll get a full refund. I do not start the timer until I fully understand the issue.**
A passionate and driven Software Architect with in-depth technical skills and a strong focus on delivery, with extensive experience at developing ultra-low-latency mission-critical trading engines for the worlds' top stock exchanges.
For over 21 years I have been a self employed software engineer. I work with my clients to take their ideas from conception all the way to final delivery. I have started three businesses which provides me the unique opportunity to see things from both the business and development perspectives.
I love discovering how things work and I'm excited to share my discoveries with you.
I am patient with everyone around me and enjoy coming up with ways to explain things in an easy to understand way.
