Ask HN: Freelancer? Seeking freelancer? (July 2025)
Please only post if you are personally looking to hire a freelancer or work as one. Agencies, recruiters, job boards, and so on, are off topic here.
I'm Phil and I have a PhD in computer engineering, specializing in operations research (mathematical optimization, constraint programming, mixed-integer programming, etc). For the past several years I've implemented custom, production-ready solutions for a variety of problems (scheduling, routing, etc). Recent work includes a constraint programming solution for goal-based selection of indexes in Postgres, a heuristics-based scheduling tool used in hundreds of vehicle workshops around the world, and an optimization model used for scheduling autoclave cycles in a drug manufacturing facility.

I am a Lead Infrastructure Engineer with 20+ years of experience.
Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.
I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.
I am located in EU (Estonia) and work remotely with occasional on-site visits.
The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.
