What We Build

Every type of web application. One delivery standard.

Whether you're building from scratch or rescuing a codebase that's become unmanageable, we bring the same engineering rigour to every project.

Discuss Your Project

SaaS Platform Development

From multi-tenant architecture and subscription billing to usage-based pricing and role-based access control - we've built the infrastructure layer of SaaS products dozens of times. You don't pay for us to figure it out on your project.

47 SaaS platforms live in production across 12 industries

Enterprise Portals & Internal Tools

Complex internal systems - CRM extensions, operational dashboards, supplier portals - built with the same attention to design and performance as customer-facing products. Internal tools should reduce friction, not create it.

SSO / SAML ERP Integration Audit Trails Workflows

Real-Time Dashboards & Analytics

Data-intensive applications with live updates, complex data visualisations, and large dataset performance - built with WebSocket architecture and frontend rendering strategies that keep the UI responsive under load.

API Design & Backend Systems

RESTful and GraphQL APIs designed for longevity - consistent error handling, clear versioning strategy, comprehensive documentation, and rate limiting built in from day one. The backend your frontend deserves.

REST / GraphQL OpenAPI Rate Limiting Webhooks

Web App Modernisation

Legacy systems rebuilt incrementally without the rewrite risk. We migrate Angular to React, untangle jQuery spaghetti, replace server-rendered pages with modern SPAs - and do it in phases so production never goes dark.

How We Work

From brief to production —
no surprises mid-way through

Transparent phases, fixed-scope sprints, and weekly client reviews at every stage. You always know what's built, what's next, and what it cost.

Why Sequere

What the best web apps share - and how we make sure yours has all of it

Speed, accessibility, security, and maintainability aren't optional extras. They're baked into our process from the first sprint.

Talk to a developer

Performance is engineered in, not bolted on

Core Web Vitals targets are set before development starts and tracked in every sprint via Lighthouse CI. Code splitting, lazy loading, image optimisation, and CDN strategy are part of the architecture - not a last-minute pass before launch.

LCP < 2.5sCLS < 0.1INP < 200msLighthouse 95+

Security is never an afterthought

OWASP Top 10 is addressed at the design stage. Authentication, authorisation, input validation, dependency auditing, and secrets management are handled as core requirements - not afterthoughts caught in a pre-launch security sweep.

You own the codebase from day one

Private Git repository, clear commit history, comprehensive documentation, and no proprietary tooling lock-in. Your internal team can pick up the codebase and run with it - by design, not accident.

Clean Git HistoryADR DocumentationNo Lock-InFull Handover

Accessibility is a standard, not an option

We build to WCAG 2.1 AA from the first component. Keyboard navigation, screen reader compatibility, colour contrast, and focus management are tested throughout - not at the end when changes are expensive.

Scalable from MVP to enterprise volume

Database indexing, query optimisation, horizontal scaling strategy, and caching layers are designed for the load you'll have in two years - not just the load on launch day. We've seen what happens when this is ignored.

FAQs

The questions we get before every web app project

Honest answers on timeline, cost, technology, and ownership. Something else? Just ask.

A focused MVP with a defined scope typically takes 10–14 weeks from kick-off to production launch. More complex platforms with multi-tenant architecture, advanced permissions, or significant third-party integrations are generally 16–24 weeks. Timeline accuracy depends heavily on how well-defined the requirements are at the start - the two-week discovery phase is where we pin this down. We've seen projects that quoted 6-month timelines get to production in 12 weeks because the discovery was thorough.
A well-scoped MVP for a SaaS or internal tool typically sits between $55,000 and $120,000. Enterprise platforms with complex integrations, security requirements, or high-traffic architecture are higher. We provide a fixed-price quote after the discovery phase - there are no sliding goalposts once we've agreed scope. The discovery sprint itself is fixed-price and gives you a complete cost estimate before committing to the build.
You own everything we produce. Source code, design files, infrastructure configuration, documentation - all transferred to you on completion. We use your Git organisation from day one, so you have full visibility throughout and full ownership from the first commit. We sign an IP assignment agreement at the start of every engagement.
Scope changes are managed through a formal change request process - we assess impact on timeline and cost, agree it in writing, and adjust the plan. We don't absorb scope changes silently and then surprise you with a bill, and we don't block progress over minor clarifications. The key is that our discovery phase is thorough enough that significant mid-project changes are rare.
We primarily build with React or Next.js on the frontend, Node.js with tRPC or Express on the backend, and PostgreSQL as the primary database. For hosting we recommend Vercel or AWS depending on scale and compliance requirements. That said, we're framework-agnostic - if your team has strong opinions, existing infrastructure, or regulatory constraints that point to a different stack, we work within those constraints rather than insisting on our preferences.
Yes, and we do this frequently. We can take full ownership of a project, or operate as senior engineering capacity alongside your team - taking specific tracks, implementing the architecture while your team builds features within it, or working in a staff augmentation model on a retainer. We write clear documentation and hold knowledge transfer sessions to ensure there's no capability dependency on us.
We offer a structured post-launch retainer that covers security patch management, dependency updates, performance monitoring, minor feature additions, and incident response. Alternatively, if your internal team is taking full ownership, we include 30 days of hypercare post-launch and a comprehensive handover package - runbook, architecture documentation, onboarding guide, and a recorded walkthrough of the codebase.
WCAG 2.1 AA compliance is a standard in our delivery process, not an add-on. We use axe-core throughout development, conduct keyboard navigation testing, review screen reader compatibility with NVDA and VoiceOver, and verify colour contrast ratios across all components. For public sector or financial services clients, we can produce a full accessibility conformance report (VPAT) on request.
