Hire Top Freelance WebSphere Developers

David Schoutens

Full-stack software craftsman and technical leader with over 15 years of experience. Equally adept at system design, programming, technical leadership, mentorship, and business collaboration. Have a wide breadth of technical experience, but specialize in backend API development, relational databases, and web applications. Passionate about simplicity and efficiency. I have worked at over a dozen companies large and small, in a handful of different domains. Also participated in hundreds of interviews, about half-and-half as the interviewer and the interviewee. I have given dozens of talks and training sessions on a variety of topics, mostly focusing on distributed systems, caching, and testing. My top skills are Java, SQL, testing, and refactoring. I have experience with formal academic and professional mentorship, and would love to help you skill up, solve a problem, or just nerd out with you today!

Kirill Erokhin

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!

Tommy Williams

I have experience in several front end and back end languages, but spend most of my time in Javascript these days.. I love working with emerging technologies and keeping up with all that surrounds Javascript. I have been working with Javascript since it's infancy, and feel that it is the single best language for any programmer to understand and master. Give me a ring if you are ready to learn! ```['B', 'R', 'E', 'A', 'K', ' ', 'S', 'T', 'U', 'F', 'F'].forEach(xD => console.log(xD));```
