Hire Top Freelance OpenStack Developers

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!

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.

Stuart Cannon

For the past 8 years I have predominantly used Python for the generation of custom data pipelines and analysis algorithms for biological science discovery. Currently, my remit is within population genetics which incorporates many different dataset types which are often terabytes in size. I am also well versed in R, Git, Linux and Bash. I enjoy creating novel algorithms but also optimising existing or legacy code.

Aleksander Korzyński

I'm happy to help you with **C**, **Bash**, **GNU make**, **Git**, **Linux** and related open-source technologies. I've enjoyed doing this stuff since the 1990s and it's got ingrained into my memory to such an extent that I seem to remember arcane stuff (like C pointers to pointers😉) even when somebody wakes me up in the middle of the night 😎 I also have a passion for helping others to grow as software engineers. I was told I ask good questions. If you ask me for advice I won't do your homework for you, but instead ask you questions that will help you come up with your own ways to improve your code or infrastructure. 🎓 I'm also a co-author of an upcoming book on Linux: *Get Started on Linux by End of Tonight – Without Breaking Your Box*.

Felix Faust

Hello there, I'm Felix. I work full time and have some spare time. In the past I built and worked on **production grade software** that scaled to thousands of users. I'm here to help you with your **coding** and **comprehension** issues, specifically (*not exclusive*) in technologies such as **Typescript, React, Kubernetes**. I can assist with a bunch of things involving - but not exclusive to: - help you to (understand how to) code - make you better at programming - find and discuss the right solution to your problems technologically: - nodejs / typescript etc. - frontend technologies such as react and angular - backend technologies such as java (+ spring framework) and nodejs - anything related to infrastructure or software architecture You may think: why chose Felix? The answer is easy. It's my hobby. And my knowledge is battle tested. I'v played key roles in multiple large migration and software projects. I know what to do and what not to do.
