FAQ
Ruby on Rails backend architecture, API design, Sidekiq background processing, and high-load system optimisation. Beyond pure Ruby, the team covers the full delivery stack: React and Vue on the frontend, React Native for mobile, PostgreSQL and Redis for data, and Docker and Kubernetes for infrastructure. We handle greenfield builds, legacy modernisation, and everything in between.
Yes. The team has shipped full-stack products end-to-end — Rails API, React or Vue frontend, React Native mobile apps, payment integrations (Stripe, PayPal, Shopify), and third-party service connections. You do not need a separate frontend agency or mobile team. We cover the full product surface from a single engagement.
Yes. Our engineers have operated at significant scale — a healthcare platform serving millions of users, an e-commerce data engine processing over 500 million product pages per day, and a fraud detection platform handling real-time risk scoring under production load. Performance optimisation, chaos engineering, SRE practices, Datadog monitoring, and Kubernetes-based scaling are part of how the team operates, not afterthoughts.
Yes. The team has worked with Rails codebases ranging from Rails 3.2 with Ruby 1.9.3 up to Rails 8 with Ruby 3.3. Legacy modernisation — incremental refactoring, adding test coverage, reducing technical debt while supporting ongoing feature delivery — is something we do without drama. If your codebase has history, that is not a problem.
Healthcare, e-commerce and retail, FinTech and fraud detection, EdTech, media and streaming (OTT platforms), food delivery, HR and enterprise automation, and AgTech. Industry context shapes how we approach compliance, data handling and integration requirements — and we bring that domain context to every engagement.
Agencies give you a named developer in the proposal and a different one on the project — often junior-heavy, managed by an account lead you only hear from on billing day. With DMexec you engage directly with the developer doing the work, and Dimmy is involved as technical sponsor on every engagement. No account manager layer, no junior fill, no markup on markup. Senior-level output at 40–60% of typical agency rates.
Fixed monthly rate per developer — no agency markup, no recruiter fees, no hidden costs. Senior Ruby on Rails developers are typically priced at a significant discount to equivalent Western-European agency rates. The rate depends on seniority, stack depth and engagement scope. Book a 15-minute call and we will give you a straight number within the first conversation.
Yes — all developers work remotely. The team is European-based, which gives meaningful US and AU timezone overlap alongside full European coverage. Daily standups, async-first communication, and direct Slack access mean there is no coordination lag. If your company operates in a specific timezone, mention it on the intro call and we will confirm overlap before any engagement starts.
