Web Application Development
Bespoke web application development for SaaS, fintech, and enterprise teams. Senior engineers, Next.js & TypeScript stack, performance budgets baked in.
01 — Approach
How we engage.
- SaaS platforms — multi-tenant architectures, billing, RBAC, and self-serve onboarding flows that don't fall over at scale.
- Internal tools & dashboards — analytics-grade interfaces with streaming data, fine-grained permissions, and audit trails your compliance team will accept.
- Customer portals — secure, branded environments where your customers do real work: file uploads, e-signatures, payments, support.
- Headless commerce & content platforms — Next.js storefronts and editorial CMS frontends with sub-second time-to-first-byte.
- Real-time collaboration apps — CRDT-backed editors, presence systems, and WebSocket pipelines battle-tested at scale.
- API-first platforms & developer tools — REST and GraphQL gateways with SDKs, documentation, and a developer experience worth charging for.
- Senior-only delivery. A staff-level engineer owns your project from kickoff to launch. No juniors quietly billed at senior rates.
- Performance budgets, not promises. We set Lighthouse, Core Web Vitals, and TTFB targets up front, then hold the line through every sprint.
- Type-safe end to end. TypeScript, strict mode, zero any. Schemas drive the database, the API, and the UI — refactors are safe by default.
- Editorial design rigour. Designers from publishing and product backgrounds. Every screen is considered, not configured.
- Documented and tested on day one. Runbooks, ADRs, and CI-enforced test coverage are part of the deliverable — not a "phase two" promise.
- Stay-on retainers. Most clients keep us on after launch to evolve the platform. Continuity beats handoff.
- Frontend: Next.js (App Router, RSC, streaming), TypeScript, Tailwind CSS, Radix UI, Framer Motion.
- Backend: Node.js, Rust (Axum / Tokio) for performance-critical services, Python where the data work calls for it.
- Data: PostgreSQL, ClickHouse for analytics workloads, Redis for caching and queues, Kafka for event-driven pipelines.
- Infrastructure: Kubernetes on AWS or GCP, Terraform, GitHub Actions, observability via OpenTelemetry and Grafana.
- Quality: Playwright end-to-end tests, Vitest units, Storybook visual regressions, Renovate for dependency hygiene.
- Fixed-scope build — $75k–$400k+, two to six months. Best for new platforms with a clear vision.
- Embedded squad — monthly retainer, two to four engineers. Best for ongoing product evolution alongside your internal team.
- Discovery sprint — $25k, two weeks. A de-risking exercise that produces an architecture, a roadmap, and a fixed quote.

04 — Common questions
Frequently Asked Questions
What does web application development cost?
Most of our bespoke web application engagements land between $75,000 and $400,000 for a fixed-scope build, depending on complexity, integrations, and timeline. Smaller two-week discovery sprints start at $25,000. We publish honest ranges because we would rather discuss budget on the first call than weeks in.
How long does it take to build a custom web application?
A typical SaaS MVP ships in 10–16 weeks. Larger enterprise platforms run four to nine months. We work in two-week sprints with a deployable staging build at the end of every sprint, so you see real progress fortnightly — not a month-three reveal.
Which technology stack do you use for web app development?
Our default stack is Next.js with TypeScript on the frontend, Node.js or Rust on the backend, PostgreSQL with Redis for state, and Kubernetes on AWS or GCP for infrastructure. We pick tools by fit, not fashion — we have shipped production work on Python, Go, Elixir, and Java when the engagement called for it.
Do you build SaaS platforms, or only marketing sites?
SaaS and product platforms are our core practice. We have shipped multi-tenant billing, RBAC, audit logging, real-time collaboration, analytics dashboards, and customer portals across fintech, healthcare, logistics, and media. Marketing sites are a small fraction of what we do.
Can you take over an existing web application?
Yes. About a third of our engagements start as inherited codebases. Our discovery phase includes a full code audit, dependency-risk report, and a written remediation plan — so you know exactly what you are buying before any rewrite work begins.
Do you offer ongoing maintenance after launch?
Yes. Most clients keep us on a monthly retainer after launch to evolve the platform — adding features, absorbing new requirements, tuning performance, and rotating the security audit. Continuity beats handoff, and the work tends to compound.
How do you ensure the web application is secure?
Security is built in from architecture, not bolted on. Every engagement includes threat modelling, OWASP Top 10 review, dependency scanning in CI, secrets management with HashiCorp Vault, and an end-of-build penetration test by our in-house cybersecurity practice. We have shipped audited platforms for banks and regulated fintechs.
Will my web app be accessible and SEO-friendly?
Yes. We deliver to WCAG 2.2 AA by default, with axe-core checks running in CI. Server-side rendering, semantic HTML, structured data, Core Web Vitals budgets, and a clean indexable URL structure are part of every public-facing build — accessibility and SEO are non-negotiable, not "phase two".
