Freelance Performance Optimization Developer - Ethar Alali
Freelance Performance Optimization Developer5.0 (28 reviews)

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).
