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!

I’m a full-stack software engineer with experience building AI-powered applications, scalable backend systems, automation tools, and modern web platforms. Over the years, I’ve worked across different areas of technology — from backend architecture and cloud infrastructure to frontend development, APIs, automation, and real-time systems. Recently, I’ve been focused heavily on AI/LLM applications, including conversational systems, speech-to-text pipelines, text-to-speech services, and language learning platforms powered by local and cloud-based models. I work primarily with: • Python (FastAPI, Flask) • Node.js / Express • React / Next.js • PostgreSQL • Docker & microservices • Firebase • AWS & Linux environments I enjoy solving difficult engineering problems, simplifying complex systems, and helping founders or teams move projects forward quickly without unnecessary overengineering. Some of the things I can help with: * AI/LLM integrations * ChatGPT/OpenAI integrations * Microservices architecture * REST APIs * Backend systems * Authentication systems * Docker deployment * Automation scripts * Web app development * Debugging difficult production issues * Performance optimization * Cloud/server setup * Speech-to-text and voice applications I also have a background in Electrical/Electronics Engineering, which shaped the way I approach systems, troubleshooting, and problem-solving in software. If you need someone who can jump into an existing project, understand systems quickly, and build practical solutions, I’d be happy to help.
Mobile app architect with 19 years of industry experience and 14+ years building iOS \Android applications: from greenfield architecture to rescuing legacy codebases. I've led teams of 15+ developers, shipped apps for high-profile clients, and specialize in turning complex requirements into maintainable, well-tested Swift, Kotlin, Java, C\C++ and Objective-C code. My technical foundation runs deep: memory management, multi-threading, comprehensive Unit and UI testing, and full project lifecycle ownership from conception to App Store deployment. I've also worked extensively with C/C++ and C# on Windows platforms, and apply Python and JavaScript where they fit the job. As a team leader since 2013, I've grown teams, built personalized developer growth plans, and helped multiple engineers advance to senior and tech lead roles. I bring the same rigor to people as I do to code. I'm known for modernizing development workflows, driving cross-team collaboration, and delivering under pressure without sacrificing quality.

Through my journey as a developer, I have 7+ years of professional experience and helped 150+ clients with their development projects across several Technologies including **Node, React, NextJS, Javascript, TypeScript, Python, C++, JAVA, Unity Game Development**. Due to my strong understanding of Data Structures and Algorithms along with programming fundamentals, I can quickly learn any new language and concept which enables me to design and develop production-level systems. My mantra is to enhance my knowledge with practical applications. I focus on writing simple, clean, consistent and beautiful programs by prioritizing a well-thought design to ensure that they are easier to debug and maintain.
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).
