Flint De Orient designs, builds, and runs the systems ambitious teams depend on — custom software, mobile apps, SaaS platforms, cloud infrastructure, ERP, and AI products, delivered by one accountable team.
Line-of-business systems built around how your team actually works — web apps, internal tools, portals, and integrations, engineered to last.
Native and cross-platform apps for iOS and Android, from first prototype to store release — with analytics and updates handled for you.
Multi-tenant products with billing, roles, and analytics built in — shipped as an MVP and grown into a platform your customers renew.
AWS, Azure, and GCP environments that stay fast, cheap, and observable — with CI/CD pipelines that make every release a non-event.
ERP, CRM, HRM, inventory, and accounting modules tailored to your processes — one connected system instead of a dozen spreadsheets.
Chatbots, autonomous agents, and applied ML that plug into your existing stack and take real work off your team's plate.
Where we work
Each of these has its own team, its own process, and its own page — covering what we build, what it costs, how long it takes, and the questions clients ask before they commit.
