Why Choose Us

A senior engineering team based in Bulgaria, partnering with US companies on custom software, SaaS platforms, and mobile applications. We focus on industries where reliability matters — construction, civic tech, and SaaS — shaping every engagement around what your business actually needs, not a fixed template.

Why Choose Us
Fixed pricing for smaller, well-scoped engagements; time and materials for larger, evolving builds. You get cost certainty where it makes sense and flexibility where the work demands it.
Most focused SaaS MVPs land in 8–16 weeks of active build time, depending on scope, integrations, and the complexity of your domain logic. Larger platforms with custom infrastructure or compliance requirements typically take four to six months.
We focus on construction technology, civic tech, and SaaS startups — building software for project workflows, public-sector platforms, and subscription products that need to scale reliably.
We are based in Shumen, Bulgaria and serve clients across the United States with overlapping US-time-zone working hours, dependable communication, and EU data-residency options when needed.
We choose the stack to fit the project, not the other way around. Our team works across modern web, mobile, and cloud technologies — selecting the right tools based on your performance needs, team handover plans, and long-term maintenance goals.
We sign NDAs as a standard part of any engagement and work with clients to meet industry-specific compliance requirements — handling sensitive data, secure architectures, and audit-ready delivery practices.
