Services
From a single integration to a whole platform.
Bring us a new idea, a system that won't talk to another, or an old application nobody wants to touch.
01 · Core focus 02 Web platforms, internal tools and client portals built around how your business works.
03 We keep the business logic that works and replace what slows you down, step by step instead of in one risky rewrite.
04 Practical AI: document processing, assistants that work over your own data, classification and workflow automation.
05 Speed, accessibility, SEO foundations and new features for the site you already have.
06 iOS and Android apps, native or cross-platform, connected to your existing backend.
07 Updates, security patches, monitoring and fixes, handled by people who know your code.
08 Architecture reviews, technology choices, code audits and a second opinion before a big decision.
Integrations
Your systems should talk to each other. We make them.
Modern APIs, old databases, CSV exports on an FTP server: we connect whatever you have and make sure you know when something goes wrong.
- ERP
- CRM
- E-shop
- Accounting
Integration layerOne place where your data is mapped, checked and delivered
- Warehouse / WMS
- Payments & banks
- BI & reporting
- Legacy database
REST, GraphQL and SOAP. We build new APIs and connect to existing ones.
Real-time or scheduled sync, one-off migrations and ETL between databases.
File drops, EDI, direct database access. We connect systems that were never meant to be connected.
Dashboards and alerts, so a failed sync is fixed before your team notices.
About Deverlin
Software we'd be happy to maintain ourselves.
Deverlin is a software development and consultancy company based in Riga, Latvia, working with clients across Europe and beyond. We started it to build the kind of systems we always wanted to inherit: clearly structured, well documented and connected properly to everything around them.
We're both passionate about fixing legacy systems and the integrations between them, and that shared interest is what brought us together. Deverlin is how we turned it into a company: helping businesses whose software is holding them back get it working the way they need.
