Hi! My name is Ethar, though you'll get away with pronouncing it "Ether".
"I love coding!" and despite that intro, I don't like sounding like Donald Trump. Not that you could ever confuse us two really :) I've been a full stack guy for over 20 years and these days, churn out JS, Node, C#, both SQL & NoSql and run on AWS, including developing IoT platforms and Alexa skills.
As well as coding help, I also encourage developers and architects to look at problems differently. Committing to effective, clean, value driven solutions is crucial and my experience both in code and business provides a unique slant on why code is written in the first place. I also regularly recruit, so understand the needs of folk trying to break into the industry.
Despite over 22 commercial years in the IT industry, holding very senior roles, and running companies and organisations, I still prefer coding. I've spent a lot of time doing complex computing tasks and building circuits, and work across IoT, AI/Machine Learning, High performing computing and use Lean-EA and Lean Startup to help enterprises and startups alike work more effectively. Many of my calls end in YAGNI (You Ain't Gonna Need It), which saves on unnecessary costs elsewhere.
Ethics? Plenty. Probably to my own detriment.
Projects: Contributed to OSS including JabaJS and a local community tech calendar Alexa Skill OSS project called "WhatGeeks" (accepting PRs if you're interested).
I am a dedicated Fullstack developer focusing on Ruby on Rails 5+ years of experience and Node (2+ years of experience) on the backend and React (2+ years) and Ember(1 year experience) on the Frontend. I am an AWS certified developer associate. I love to learn new technologies, use and teach them.

“Solid guy. Has a clear understanding of C++ fundamentals and was patient and unafraid of helping with a rather subtle C++ bug that was also part of an algorithm TOO complex to explain in a single session. Meaning he had to help me debug WITHOUT understanding what the code actually does. Despite these obstacles he was able to give me not one but TWO possible approaches to solve the problem. And he managed to do so within 45 minutes of us discussing together (keeping my learning costs down for a problem that easily could've been very expensive for a run-of-the-mill tutor to deal with). While i'm not a C++ expert, I am a strong python3 dev, and I would gladly have hired Scott to work on one of my teams back when I was in the industry and strongly encourage you to book a session with him if you are on the fence.“

How does personalized Query Optimization mentoring differ from traditional classroom learning?
Personalized Query Optimization mentoring through Codementor offers a unique and effective learning approach compared to traditional classroom learning, particularly in these key aspects:
Customized content: Personalized mentoring adapts the learning material and pace specifically to your needs and skill level. This means the sessions can focus on areas where you need the most help or interest, unlike classroom settings which follow a fixed curriculum for all students.
One-on-one attention: With personalized mentoring, you receive the undivided attention of the tutor. This allows for immediate feedback and detailed explanations, ensuring that no questions are left unanswered, and concepts are fully understood.
Flexible scheduling: Personalized mentoring is arranged around your schedule, providing the flexibility to learn at times that are most convenient for you. This is often not possible in traditional classroom settings, which operate on a fixed schedule.
Pace of learning: In personalized mentoring, the pace can be adjusted according to how quickly or slowly you grasp new concepts. This custom pacing can significantly enhance the learning experience, as opposed to a classroom environment where the pace is set and may not align with every student’s learning speed.
Practical, hands-on learning: Mentors can provide more practical, hands-on learning experiences tailored to real-world applications. This direct application of skills is often more limited in classroom settings due to the general nature of the curriculum and the number of students involved.
Personalized mentoring thus provides a more tailored, flexible, and intensive learning experience, making it ideal for those who seek a focused and practical approach to mastering Query Optimization.
