Full stack development
Create and optimize full stack solutions for your growth
At COAX, we build systems that scale with your ambition, as our architectures always think ahead. As a full-stack development company, we stitch together the invisible (APIs, databases, cloud ops) and the engaging (UI, UX, functional integrations) so your software accelerates on autopilot. From concept to deployment, we deliver tailored solutions that check off all boxes.
Our full-stack development services
Our teams create front-ends using React.js for dynamic applications, Next.js for server-rendered solutions, and Webflow for no-code solutions, with TailwindCSS for utility-first styling, Material UI for Google's system, Ant Design for enterprise components, and Bootstrap for rapid prototyping. You get responsive layouts, consistent design systems, and full interactivity.
We build high-performance systems with Node.js, Express.js, Ruby on Rails, Python, or Meteor.js, tailoring the stack to your data and security needs. Whether it’s real-time APIs with Node/Express, MVC development in Rails/Django, or reactive full-stack efficiency with Meteor.js, our full stack services guarantee faster response times and lower server costs.
Our engineers build cross-platform mobile apps with React Native and native applications for iOS (Swift) and Android (Kotlin), optimizing each approach for performance and platform-specific capabilities. You get faster deployment with shared code where possible, native-level UX where needed, and apps that maintain responsiveness at any load.
We automate deployments and optimize cloud environments using DigitalOcean, AWS, Google Cloud, or Azure, configuring infrastructure as code for your full stack solutions. This ensures automated scaling, precise monitoring, and resilient architectures that maintain uptime while optimizing cloud spend.
We implement server-side rendering, structured data markup, and automated SEO workflows (meta tags, XML sitemaps, canonical URLs) alongside performance optimizations like image WebP conversion, critical CSS injection, and code splitting—ensuring technical crawlability and lightning-fast load times. Your site gains higher search rankings and sustained traffic growth.
Architecture patterns you get from the top frontend development agency
/ 01
Single Page Applications (SPA)
We build SPAs that ditch full-page reloads and are perfect for dynamic dashboards, real-time analytics tools, and complex web apps with instant data updates, slashing server overhead.
/ 02
Server-Side Rendering (SSR)
We provide front-end development services with Next.js to pre-render pages on the server — ideal for e-commerce platforms, content hubs, and SEO-critical applications for content stability.
/ 03
Static Site Generation (SSG)
We deploy SSG via Gatsby to pre-build bulletproof pages at compile-time, just right for marketing sites, documentation portals, and high-traffic content platforms to maximize uptime.
Our custom backend development system architecture styles
Monolithic architecture
We craft one-codebase monoliths for lean projects with centralized logic, single-point debugging, and frictionless deployment, giving you faster iteration cycles and rock-solid stability.
Microservices architecture
Our backend development services deploy microservices for SaaS platforms and enterprise systems, where autonomous scaling of core functions and tech freedom let you innovate faster.
Event-driven architecture
We engineer reactive backends where services autonomously trigger real-time actions, great for live chat, IoT dashboards, and financial tracking, giving you zero-message-loss resilience.
Service-oriented architecture (SOA)
As a proven backend app development company, we modernize legacy systems by breaking them into reusable services, letting your finance, CRM, and inventory modules share data.

What our clients say about COAX
Full stack app development process: How we work
We kick off our full stack web development services by auditing your existing systems, business needs, and technical constraints to assess everything from legacy codebases to cloud environments. This includes analyzing API documentation, database structures, and authentication protocols to ensure the right development paths.
The next step of our services is breaking down the integration into phased milestones, prioritizing critical API connections and data migration tasks while accounting for testing cycles and team dependencies. Our technical leads draft a plan that sequences database synchronization, feature rollouts, and fallback procedures to ensure efficient implementation.
Our staffing process matches your integration challenges with specialists who've solved comparable technical puzzles before, whether that means bringing in DevOps engineers familiar with your cloud setup or developers certified in the specific third-party platform you're implementing.
When providing full stack development outsourcing, we pay close attention to the UI/UX stage. We create tech specifications for each integration point, documenting data flow diagrams, API contracts, and error handling protocols. It includes authentication methods, data transformation rules, and fallback mechanisms for failed transactions before actually coding anything.
Our engineers implement the designed solutions using feature flags, writing integration code that first establishes basic connectivity before progressively adding complexity like caching, retry mechanisms, and data synchronization routines. Each module undergoes peer code reviews and static analysis to maintain quality before moving to testing.
We execute comprehensive test suites covering integration points, including contract testing for APIs, data integrity validation, and failure scenario simulations to ensure graceful degradation. Our QA engineers validate the integration end-to-end, performing load testing on data pipelines, security scanning on authentication flows, and usability testing on any modified interfaces.
As a full stack development company that values our reputation and your success, we deploy solutions with zero-downtime migrations, ensuring synced updates across frontend interfaces, backend services, and database layers. Our team monitors the ecosystem post-launch, addressing everything from component updates to microservice scaling.
Frequently asked questions and answers
Full stack development means building both the frontend (what users see) and backend (server, database) parts of a web application. A full stack developer handles everything from designing interfaces to writing server code.
Web development is a broad term for building websites or web apps, which can focus only on frontend or backend. Full stack development specifically covers both frontend and backend together in one project.
A full stack web development company like ours typically offers multiple hosting choices like shared servers for small apps, cloud platforms (AWS, Azure) for scalability, and dedicated servers for high-traffic projects. They help pick what fits your app’s needs and budget.
Outsourcing full-stack development gives you a complete solution from one team, saves costs, and speeds up development since experts handle both frontend and backend together.
Yes, our full stack web development service includes post-launch support including bug fixes, updates, and performance optimizations to keep your application running smoothly.
