Architecture for Long-Lived Platforms
Stack and architecture decisions made with year-five maintenance in mind: TanStack Start, React, TypeScript, and conventional infrastructure your internal team can operate without re-hiring the agency.
A custom web development agency for enterprise applications. We design, build, and hand off long-lived web platforms that integrate with the systems of record your business already runs on, with the documentation and operational rigor an internal team can take over on day one.
Capabilities
Stack and architecture decisions made with year-five maintenance in mind: TanStack Start, React, TypeScript, and conventional infrastructure your internal team can operate without re-hiring the agency.
CRM, ERP, identity providers, data warehouses, and internal services wired in cleanly through documented contracts. The integrations that connector catalogs do not cover.
Okta, Azure AD, Google Workspace, SCIM provisioning, role-based access enforced in the application layer, and the audit-log surface compliance regimes demand.
Multi-stage approvals, role-gated drafts, scheduled regional rollouts, headless CMS shaped around the workflow you actually run, not the one a page builder modeled for you.
OpenAPI specifications, llms.txt, and Model Context Protocol surfaces designed in from the start so the platform is callable by the AI agents your enterprise is already being asked to expose to.
Core Web Vitals budgets, structured logging, error tracing, rate limiting, and security posture built into the platform, not bolted on after launch.

How We Work
Enterprise engagements have stakeholders, dependencies, and audit trails that mid-market builds do not. Our process is shaped to fit that reality.
We map the full set of stakeholders, systems of record, integration points, and compliance constraints before architecture. The deliverable is a written technical scope an internal steering committee can review.
Stack and architectural decisions are written down as Architecture Decision Records, so the rationale survives the engagement. Stack choices favor maintainability and hiring pool over novelty.
Two-week iterations with working software at every checkpoint. Stakeholders see the platform evolve in their browser, not in a slide deck.
Real integrations exercised against staging copies of the systems of record. Test suites, accessibility audits, and audit-log evidence produced as a deliverable, not as an afterthought.
Documented architecture, runbooks, on-call playbooks, and pair-programming sessions with the internal team. The engagement ends when your team can extend the platform without us.
For teams that want a continuing advisory relationship, we stay engaged through feature expansion, performance work, and the next platform iteration.

FAQ
Enterprise web development is the discipline of building long-lived web platforms that integrate with systems of record (CRM, ERP, identity provider, data warehouse), enforce role-based access, satisfy compliance regimes, and are operable by an internal team for years after launch. A custom website build optimizes for design and marketing surface. Enterprise web development optimizes for integration depth, observability, and hand-off.
Both. A meaningful share of our enterprise engagements start with an existing platform that needs to be modernized, integrated with new systems, or extended with AI-agent surfaces. We assess the codebase, write down what we found, and propose a scoped path forward before any rewrite work is committed.
Time-to-first-deploy in week one, full-stack coverage from a senior team, and a clean hand-off to an internal team that will own the platform afterward. For one-time platform builds and integration-heavy projects, an agency engagement usually beats the cost and ramp time of staffing a full in-house team. For high-velocity ongoing product work, an in-house team is the right call. See our article on hiring an agency vs. building in-house for the full decision framework.
We design the platform so the public HTTP surface is callable by AI agents from day one: OpenAPI 3.1 specification at a predictable URL, llms.txt for AI search crawlers, and a Model Context Protocol server exposing the read-only tools agents need. Our own site implements all three, so we can point to a working reference instead of describing one.
For new builds we default to TanStack Start or Router on Vite, React, TypeScript, Shadcn/ui, and Tailwind. The stack is portable across deployment targets (Azure App Service, AWS, on-prem Node), end-to-end type safe, and operable by any senior React engineer.
