End-to-end custom software engineered for performance and scale — from concept to production-ready deployment, at the edge and on-chain.
What We Build
Custom apps, database architecture, edge deployment, on-chain contracts, and the messaging layer that ties them together — complete engineering for businesses that need it built right.
Custom web applications and mobile-first platforms engineered to your exact specifications. React, Next.js, and Vite frontends — plus plain HTML and vanilla JS when that is the right tool — with clean, maintainable architecture built from the ground up.
Structured data architecture, schema design, and multi-platform database integration. We connect your systems, normalize your data, and build the APIs that make everything work together seamlessly.
Cloudflare-native deployments — serverless Workers, R2 object storage, D1, and static assets at the global edge. We architect infrastructure that scales without the overhead of bloated platforms.
Production Solidity contracts for escrow, payment splitting, vesting, token gating, on-chain records, and governance. Written, compiled, and deployed to EVM networks — with a browser-based compiler and deployer toolchain we built in-house.
SMS, voice, and transactional email wired directly into your application — dispatch alerts, appointment reminders, OTP verification, and delivery confirmations. Built on Twilio and Cloudflare Email Routing.
Third-party API wiring, webhook pipelines, and service integrations that unify your tools into one working system — payments, project management, authentication, document generation, and beyond.
Deployed Platforms
A family of field-service and operations platforms built under the dbappsystems.com umbrella — each one a complete authenticate, dispatch, complete, invoice workflow for a different trade.
