-->> 10+ years of experience in Development / Providing Customized Generative AI powered Solutions / Consultations work and have worked for everything from small business to unicorn startup.
**WHAT I AM LOOKING FOR**
Opportunity to collaborate with startups who are in search of a partner to build their ideas; with enterprises to transform their operations into impact-full solutions.
I am a senior full-stack & DevOps developer with a track record of maintaining distributed infrastructure, recent deep experience in large-scale data pipelines and a growing skillset and interest in applied AI/LLM integration.
My recent work at an e-commerce search engine startup had me building and maintaining scrapers and a data pipeline that ingested over 10M product SKUs into an OpenSearch index, which was used for hybrid vector+lexical product search, enriched with LLM signals extracted as part of the pipeline. I've used reranking techniques like RRF to enhance relevance after retrieval, and RAG/grounding for features that answered personalized user queries with recommendations grounded in real customer reviews.
My earlier work was heavily full-stack and always involved infrastructure where I often built and supported systems end-to-end, very often in context of a regulated market - with great examples like Deckard (PropTech/GovTech), Sick Children's Hospital/RareConnect (Healthcare-adjacent), and Ethoca \[now MasterCard\] (FinTech).
I've also led IaC initiatives at Ethoca (Chef/Ansible, in 2016-17), and even implemented IaC from scratch for two startups - Pastel Labs (Terraform automation of AWS infrastructure for a B2B SaaS and a tutoring marketplace, in 2021), and Rilara (Pulumi for AWS infrastructure of their e-commerce product, in 2025-26).
My startup experience is proven track record of working independently, but I also thrive as part of a team, with most recent example of being part of Deckard's distributed remote engineering team of 25+ people spread across the US and Australian timezones.
Claude Code is part of my everyday workflow, and I am happy to consider myself a relatively-older senior developer who has successfully adapted to an AI-assisted/AI-first SDLC without compromising the quality of my work.
I would be very excited to continue my journey with an opportunity in healthcare or finance, where I could apply my IaC skills while continuing to explore the world of LLM applications to improve user experience in these regulated environments.
Should you have any questions about any of the background I mentioned here or on the attached resume, I would be glad to answer them in an interview at a time of your convenience.
Thank you!
Senior software engineer with 10 years of experience. Started out in the trenches coding, fueled by solving tricky problems and getting hooked on software and data architecture.
My passion lies in building products, leading teams and writing simple and efficient code.
Hi! I love Java, Python, Javascript, distributed systems, large scale systems, machine learning, natural language processing and image processing. My work has been featured on the AWS blog (https://tinyurl.com/chaosrunner), The Guardian (https://tinyurl.com/topvocab) , Billboard.com (https://tinyurl.com/topprofane) and other print/digital publications. I also own Amazon's chaos testing framework called AWSSSMChaosRunner (https://github.com/amzn/awsssmchaosrunner).
I am a Senior Engineer at Amazon's Prime Video and have worked on scaling backend systems to millions of transactions-per-second, utilising various cloud technologies and primarily working with Java, Kotlin and Javascript. This involves image/audio/text processing systems, creating & managing databases/APIs for mobile/web applications and everything in between. I have 15yrs+ experience with backend engineering, cloud tech, nlp, signal processing and image processing. I can help you with any of these topics.
I also love hackdays and have attended 20 hackdays in Europe in the last couple of years and collaborated with beginners/experienced developers on different kinds of projects.
Thanks for reading and hope to talk to you soon!
Hi! My name is Ethar, though you'll get away with pronouncing it "Ether".
I've been a full stack guy for almost 30 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 almost 30 years of 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).
**Currently leading the engineering team at the biggest online conference company in the world!**
Software Engineer since 14.
Background in ERP application development.
Consulting/mentoring teams to achieve faster development pace, remove technical debt and improve their programming and architectural design abilites.
