Services
What we do
Hands-on engineering across the whole delivery and operations lifecycle, from the first commit to production and beyond.
CI/CD & GitOps
Fast, reliable pipelines that build, test, scan and deploy automatically. GitOps workflows so every change is reviewed, versioned and easy to roll back.
Cloud, hybrid & on-prem
Public cloud, private data centre or a mix of both. Migrations, landing zones, networking and cost optimisation, chosen for your needs rather than a vendor's.
Infrastructure as Code
Reproducible, documented infrastructure defined in code and kept in Git. No snowflake servers and no undocumented manual steps.
High availability & DR
Architectures that stay up when components fail: redundancy, load balancing, clustered and replicated MySQL, MariaDB and PostgreSQL, tested backups and clear recovery objectives (RPO/RTO).
Security & patching
System hardening, automated OS and application patching, vulnerability and image scanning, secrets management and least-privilege access. DevSecOps built into the pipeline.
Observability & SRE
Metrics, logs, traces and meaningful alerts, so problems are spotted before users notice. SLOs, runbooks and calm incident response.
AI infrastructure & MLOps
Running AI workloads in production: GPU scheduling on Kubernetes, self-hosted LLMs, model serving and pipelines, plus practical AI-assisted automation for engineering teams.
About us
Small by design
Profimedia is an independent consultancy of a few experienced developers and DevOps engineers, based in London. We are not a large agency and we don't pretend to be one.
That works in your favour. There are no account managers or sales layers: you speak directly to the engineers who design, build and support your systems. Decisions are quick, communication is straightforward and the people who build it are the people who answer the phone.
Our background covers both software development and operations, so we understand what development teams need from a platform, and what it takes to keep it running at 3am.

FAQ
Common questions
How big is Profimedia?
We are deliberately small: a few experienced developers and DevOps engineers. You work directly with the engineers doing the work, with no account managers or sales layers in between.
Do you only work with cloud platforms?
No. We work across public cloud (AWS, Azure, Google Cloud), on-premises and bare-metal environments, and hybrid set-ups that combine both.
Can you help with an existing Kubernetes cluster?
Yes. We regularly review, upgrade, secure and stabilise existing clusters, as well as build new ones. Our team includes a Certified Kubernetes Administrator (CKA).
Do you work with databases?
Yes. We install, tune, upgrade and migrate MySQL, MariaDB and PostgreSQL, and build highly available set-ups such as MariaDB Galera Cluster and PostgreSQL replication with Patroni, including backups and point-in-time recovery.
Do you offer ongoing support and patching?
Yes. Alongside one-off projects we offer ongoing arrangements covering OS and application patching, Kubernetes upgrades, monitoring and general infrastructure maintenance.
Do you work remotely?
We are remote-first and based in London. We work with clients across the UK, and can meet on site in London when useful.
