Web apps that earn their keep

Web application development is the work of designing, engineering, and operating software that runs in the browser — SaaS products, internal tools, customer portals, and data-heavy dashboards. At MarkAge360 we handle the full stack: product and architecture discovery, frontend and backend engineering, APIs and databases, authentication and permissions, third-party integrations, and the deployment and monitoring that keep it running. You get one accountable team from the first wireframe to a live, supported app.

Cost depends on scope — the number of user roles, screens, integrations, and how much custom logic and data the app handles. We scope and price after a short discovery so the estimate reflects your actual workflows, not a guess. Where it helps, we shape the work into a phased build: a focused first release that proves value, then funded iterations, so you control spend and see working software early rather than paying for everything up front.

A focused first release typically lands in weeks rather than months, and larger platforms grow from there in funded phases. We work in stable, testable sprints with a usable build you can review throughout, so you are never waiting until the end to see progress. Timelines firm up after discovery, once the architecture, integrations, and the scope of your first release are clear.

Off-the-shelf tools are the right call when your process fits theirs and you are happy to adapt to how they work. A custom web app makes sense when your workflows, data, permissions, or integrations are a competitive edge that generic software forces you to compromise. We are candid about this in discovery — if a configured platform or integration will serve you better than custom code, we will tell you, because the goal is the outcome, not the build.

We build modern full-stack web apps — component-driven frontends, typed service layers, REST and GraphQL APIs, relational databases like Postgres with caching and queues, and token-based auth with role-based access control. Integrations such as Stripe, Auth0, and your existing systems are wired in as first-class parts of the build. We choose the stack to fit your team, scale targets, and what you will need to maintain after launch — not to chase a trend.

Architecture, security, and observability are built in from discovery, not bolted on at the end. We ship with QA, security checks, performance budgets, and monitoring in place, plus authentication, role-based permissions, and scaling foundations so the app stays fast and dependable as usage grows. After launch we watch real metrics — uptime, p95 latency, throughput, and errors — so issues surface and get resolved before your users feel them.
