Gotham Coders

Based in Enschede, Netherlands, Gotham Coders is a small systems engineering firm focused on mission-critical software for high-complexity domains. The team works with organizations in healthcare, manufacturing and supply chain, sports performance, and research-driven sectors, building platforms for clients dealing with tertiary care workflows, multi-warehouse inventory management, athlete sensor data processing, and life-critical medical device software. With a team of 1-10, the firm positions itself around engineering rigor rather than volume of output, targeting enterprises that need resilient, auditable systems rather than standard web or app builds. The firm's declared specialisms include ERP systems for manufacturing and supply chain workflows, Hospital Management & Information Systems (HMIS) for clinical environments, multi-tenant B2B SaaS platforms, and data-heavy research and industrial analytics systems. Its technical approach centers on event-driven architecture, where components communicate through asynchronous events rather than synchronous requests, alongside offline-first design so systems continue functioning without connectivity and sync data once it is restored. Data integrity is addressed through immutable audit logs that record every transaction and state change, supporting audit-safe and strict validation requirements. Beyond systems engineering, the agency also lists broader digital services including SEO, mobile app development, social media marketing, AR/VR development, content marketing, custom software development, email marketing, and web development. The company offers interactive product demos of its ERP and HIMS systems to illustrate inventory tracking, audit trails, and clinical workflow handling.
