From greenfield web applications and cross-platform mobile apps to custom analytics dashboards and architecture reviews — we bring engineering rigour and product thinking to every engagement.
WHAT WE DO
Fast, scalable web applications built for the modern web.
We engineer full-stack web applications using Next.js, React, and TypeScript. From lean marketing sites to complex data-heavy platforms, we prioritise performance, SEO, accessibility, and long-term maintainability from the first line of code.
Faster load times, higher search rankings, and a codebase your team can confidently extend.
Server-side rendering and static generation with Next.js
TypeScript-first codebases for long-term confidence
Headless CMS integrations (Sanity, Contentful, Strapi)
REST and GraphQL API design and integration
Core Web Vitals and Lighthouse performance optimisation
CI/CD pipelines with automated test suites
Native-quality cross-platform apps for iOS and Android.
We build mobile applications with React Native and Expo — delivering near-native performance and UX from a single shared codebase. Whether it is a consumer app, a data-heavy internal tool, or a real-time business application, we engineer it to perform and to last.
Reach iOS and Android users from a single codebase — without sacrificing quality or doubling cost.
React Native and Expo for cross-platform delivery
Near-native performance with smooth 60fps animations
Offline-first architecture where required
Push notifications and background services
App Store and Google Play deployment
REST and GraphQL API integrations
Interfaces that make complex products feel simple.
Good design is not decoration — it is clarity of purpose. We deliver research-backed UX that reduces friction, builds trust, and supports business goals. From early wireframes to production-ready design systems, we cover the full design lifecycle.
Lower bounce rates, higher conversions, and a visual identity that earns user trust from the first interaction.
User research, journey mapping, and competitive analysis
Wireframing and high-fidelity prototyping in Figma
Component-based design systems and style guides
Accessibility audits aligned with WCAG 2.1 AA
Responsive, mobile-first design for all viewports
Developer handoff with annotated Figma specs
Turn raw data into decisions your business can act on.
We build custom analytics dashboards and reporting pipelines that surface the metrics that matter to your team. From Power BI reports to bespoke web dashboards, we help organisations move from spreadsheets to real-time business intelligence.
Replace slow manual reporting cycles with automated, accurate dashboards that your whole organisation trusts.
Custom real-time dashboards for web and desktop
Power BI report design and workspace management
Data pipeline and ETL process design
SQL query optimisation for reporting workloads
Role-based access control and data governance
Automated scheduled reports and threshold alerts
High-converting storefronts engineered for performance.
We build e-commerce experiences that balance speed, conversion, and operational maintainability. Whether you are launching a new DTC brand, migrating from a legacy platform, or adding commerce to an existing product, we engineer storefronts that perform under real load.
Faster pages directly improve conversion. We build stores that are quick to browse, straightforward to manage, and easy to scale.
Headless commerce architecture with Next.js
Stripe, PayPal, and multi-provider payment integrations
Checkout funnel design and conversion optimisation
Core Web Vitals performance on product listing pages
Cart, wishlist, and user account flow design
Order management and fulfilment service integrations
Technical strategy for teams navigating real complexity.
Technical problems rarely announce themselves clearly. We help engineering teams and leadership understand their architecture, quantify risk, and define pragmatic paths forward — whether that means incremental refactoring, targeted modernisation, or a full strategic reset.
Make informed engineering decisions before they become expensive mistakes — with an outside perspective grounded in real-world experience.
Architecture reviews and comprehensive technical assessments
Technology selection and stack modernisation guidance
Performance audits and actionable optimisation roadmaps
Engineering process and CI/CD workflow improvements
Legacy system analysis and modernisation planning
CTO-as-a-service for early-stage companies

WHY NEXTENA
We build for longevity, not just deadlines. Clean architecture, typed code, and solid tests are non-negotiables on every project.
Short feedback loops, frequent releases, and working software you can evaluate — weeks to initial delivery, not months.
We think like builders, not just contractors. We challenge scope, ask why, and keep the end-user in focus at every decision point.
Systems your team can actually understand, modify, and extend. We write code as if the next developer is hostile and the next deadline is tomorrow.
No hidden blockers, no surprises. You own your codebase from day one with full visibility into progress, risk, and trade-offs.
We support what we ship. Many clients return for follow-on phases, maintenance, and new products — because we are invested in their success.
