We build web platforms, APIs and cloud systems for scale-ups and agencies across Europe. ### Where are you based, and which time zones do you work in? We are based in North Macedonia (CET) and work in your time zone anywhere in Europe, with working hours that match your team’s. We speak English, Macedonian and Serbian. ### What do you build? Customer-facing web platforms on a headless CMS, plus the APIs, back offices and data pipelines behind them. We also build serverless and container-based cloud setups, connect commerce, payment and partner APIs, add AI features to products, and make internal tools and PWAs. ### Which technologies do you use? On the web and back-end side: Contentful, React, Astro, Vue, C#, F#, Laravel, Node.js and PostgreSQL. In the cloud: AWS (Lambda, SQS, DynamoDB, RDS) and Azure. For AI features: Claude and other LLM APIs. ### How do engagements and pricing work? There are three ways to work with us: embedded engineers who join your team for a quarter or longer, a fixed-scope project with a fixed price or a capped budget, or white-label capacity for agencies under your brand. We start with a short call and a written scope with risks, an estimate and what we need from you. A support retainer is optional. ### Do you use AI in your work? Yes. We use AI for code, tests and review, but a person reads and owns everything that ships. We also build AI features into client products, with a human reviewing what ships. ## Tell us what you're building. A software startup from North Macedonia.
