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!
**AI, AWS, Cloudformation, Security & Terraform expert with 15 zero-downtime migrations under his belt.** **Executive Summary** Experienced Engineering Manager & Fractional Executive with a robust background in cloud architecture, agile methodologies, artificial intelligence, automation & security. Adept at leading engineering teams (and teams of AI agents) to deliver high-quality software solutions, optimizing system performance, and fostering a culture of continuous improvement. Expert in scalable multi-application cloud based reliability engineering, debugging, security and uptime management. Jason has migrated apps for companies with staff ranging in size from 10-250, though early in his career he worked for several very large organizations including Oakland County's Information & Technology department. He has over 10 years of recent experience serving as the lone infrastructure operator for a very large SaaS providing 24/7/365 on-call 1-hour response time for several clients while maintaining 99.999% uptime. Working in high pressure privacy oriented production emergencies is where he really shines. **Personal Description** "I have been writing code since age 4, networking since age 12 and server administration since age 15. I am not only a coniseur, but also a master artist, of code in any language. I have always worked alone, and striven for perfection, but never quite got there. AI has changed that and I am now achieving not just perfection, but absolute masterpieces in 1/10 or less time than I ever thought possible. As a polymath, I've always been on or near the bleeding edge of technology, staying agile and adaptable, rarely repeating stacks from project to project, always using the best tool for the purpose. The advancement in agentive AI over the past 6 months, when properly utilzed in experienced and demanding hands such as myself, basically turns me into a team of 20...with unlimited knowledge and zero time required to learn new APIs/toolkits/etc." \- Jason \* I publish very little code because nearly everything I do is highly proprietary and protected by NDAs. \* Also, as a security minded programmer - my entire life - I have focused very much on privacy and anonymity.
Thrived in start-up environments and teams that do battle daily for product and customer success. I have successfully designed and built systems in various landscapes, industries, and infrastructures.
Software engineering is a healthy mix of science and art - that's what I live my life by! I love tinkering with software (and hardware), and making things work and play together nicely. I enjoy learning new things and strongly believe that continuous education is the only way for all of us to evolve. I've been working with web technologies since the early beginnings of my career and had an opportunity to explore the full stack - from the data backends (often databases) through application servers, webservers and proxies to client side programming with HTML, CSS and JavaScript. I get easily excited with (new) technology and often can't resist getting my hands dirty by playing with and often contributing to exciting technologies like AngularJs, NodeJs, Cassandra and many more. My goal is to have lots of fun while creating solutions with technology, using established best practices or exploring new ones and working with people who I admire and can call friends. Specialties: HTTP, WebApp Security, CSS, XML, HTML, JavaScript, Node.Js, AngularJS, Cassandra, Redis, Neo4j, MySQL, Java, C

I'm an experienced systems engineer focusing on highly available systems design, operation and troubleshooting. I love opensource software and have a desire for deep knowledge of all technology I work with.
I've been a passionate computer nerd ever since I could remember. Mainly being self-taught, I'm always infatuated with the backend of software and applications. Trying to see the inner infrastructure and servers that are able to handle hundreds of thousands of request per second. I'm also the person who loves problem-solving no matter how challenging it is. If I need to learn a framework to implement a patch or fix a bug, I will stay up till 4 am with 2 cans of Redbull and 23 stack overflow tabs. Overall, I love to help spread knowledge of one of the best careers and skillset existing today and solve problems for people.
