Team_

devlr is a close-knit team of developers and IT professionals based in Europe. We started this company because we kept seeing the same problems: unreliable vendors, rushed deliveries, bloated SaaS bills, and clients who had no real ownership of their own systems. We knew there was a better way — and we built devlr around it.

We treat clients as long-term partners, not project tickets. When you work with us, you work directly with experienced people who take real pride in what they build. No hand-offs to junior developers, no disappearing after go-live, no hiding behind a support queue. If something isn't the right solution for your situation, we'll tell you — even when that's not the most profitable answer for us.

We build on open-source foundations - not because it's fashionable, but because it produces more reliable, auditable, and long-lived software. The open-source movement has given the world Linux, PostgreSQL, and countless other tools that have quietly run critical infrastructure for decades. We're comfortable on that foundation, and businesses that build on it tend to be more resilient and less exposed to the pricing whims of any single vendor.

We believe in data sovereignty. Your data should stay in jurisdictions you control, under rules you understand. That's why we prefer European-based infrastructure providers, and why GDPR compliance is a starting point rather than a finish line for us.

We have no interest in proprietary, extractive business models that lock customers into ecosystems designed to maximise vendor revenue. We help our clients own their stack — moving away from expensive SaaS subscriptions toward self-hosted alternatives that serve the business rather than the vendor. That often means meaningful, lasting savings on infrastructure.

We prefer proven, reliable technology over chasing hype. Boring infrastructure that works beats clever solutions that fail at 2am. The same philosophy applies to AI: as developers, we understand its capabilities well — which is exactly why we use it selectively, only where it genuinely outperforms simpler, more deterministic approaches.

Odoo is our most established specialism. It's a powerful open-source ERP and business platform used by hundreds of thousands of companies worldwide — but getting the most out of it takes experience with the hard problems: bloated databases, slow queries, integrations that break under load, and modules built quickly but not built well.

We handle custom module development, third-party integrations, deep PostgreSQL tuning, high-load optimisation, and business intelligence setups that give you real visibility into your data.

We also help companies transition from Windows to Linux workstations — a move that improves both freedom and long-term cost.

FHIR and HL7 consultancy is another area where we operate. Healthcare data interoperability is one of the more demanding corners of software development — technically complex, heavily regulated, and with little room for error. We work with healthcare organisations, insurers, and digital health teams through a certified specialist, helping them design and implement systems built on structured clinical data, REST-based integrations, and terminology standards like SNOMED CT, LOINC, and ICD-10.

With the EU's European Health Data Space regulation progressively coming into force, the pressure on healthcare providers to modernise their data infrastructure is only growing — and we're well positioned to help navigate that transition with the rigour it demands.

Beyond software, we're building out a new practice in energy efficiency and environmental monitoring — in collaboration with a European hardware partner. Offices and production facilities burn through energy in ways that are rarely measured and almost never optimised: heating spaces that aren't occupied, running equipment outside ideal temperature ranges, missing the slow drift in humidity that quietly degrades sensitive hardware or materials.

We're developing IoT infrastructure that puts that data in front of the people who can act on it — real-time dashboards, threshold alerts, and long-term trend analysis across temperature, humidity, air quality, and energy draw. It's early work, but rooted in the same principles as everything else we do: open standards, European infrastructure, and a preference for understanding a problem deeply before throwing technology at it.
