What our clients say about us.
Common questions answered.
Full stack development covers both the frontend (user interface) and backend (server, database, APIs) of a web application. A full stack team handles the entire project lifecycle from design to deployment — giving you a single accountable partner for every layer of your application.
A focused MVP with core features typically takes 8–12 weeks. A full-featured platform with integrations, admin panels, and advanced features ranges from 16–32 weeks. We provide detailed timelines after a discovery workshop.
Yes — as a certified Microsoft partner, we specialise in integrating custom applications with Dynamics 365 Finance, Sales, Business Central, Power BI, Power Automate, and Azure services. This is a key differentiator of our full stack practice.
Yes. We offer flexible support models from 30-day post-launch coverage to ongoing monthly retainers with defined SLAs. Most clients stay with us for feature development, performance optimisation, and monitoring after go-live.
Three things: end-to-end ownership (we don't silo frontend, backend, and DevOps), Microsoft ecosystem expertise (our custom apps integrate natively with D365), and a 98% client satisfaction rate built on transparent communication and measurable delivery.
Absolutely. Legacy re-platforming is a significant part of our practice. We assess existing codebases, plan phased migrations to modern stacks, and execute zero-downtime cutovers. We've re-platformed from .NET WebForms, PHP, Classic ASP, and older React versions.
