From discovery to continuous improvement in five stages.
A clear, senior-led process that connects development to SEO, paid media and analytics. See the full ONBOARDTECH process.
Discovery & Strategy
We start with your business goals, audience, digital footprint and competitive landscape, then define the architecture, integrations and success metrics for the build.
Design & UI/UX
Wireframes, prototypes and full UI/UX execution so the interface is intuitive, on-brand and designed to convert.
Development & Automation
Our full-stack developers build scalable backends, APIs and frontends, integrate CRM, e-commerce and marketing automation, and tune performance and load speed.
SEO & Paid Media Optimization
Technical SEO, schema and AI-search structure ship with the build, and the site is wired for paid media, tracking and retargeting.
Analytics & Continuous Improvement
We monitor performance with analytics dashboards and refine UX, automation and campaigns continuously to scale results.
Developers who understand marketing. Marketers who ship code.
Your website is the foundation of every campaign. We build it that way.
Search-ready from the first commit
Architecture, schema and Core Web Vitals are handled during the build, not bolted on later. Explore our SEO & AI Search service.

Full-stack web development, answered.
Full-stack web development covers every layer of a website or web application: the front end visitors see, the back end and database behind it, the APIs that connect other systems, and the hosting and infrastructure it runs on. One team owning all layers means fewer hand-offs, faster performance and a build that is aligned with search, paid media and automation from day one.
Front end: React, Angular, Vue.js and Next.js. Back end: Node.js, Django, Flask, Ruby on Rails, Laravel, Symfony, Vapor and Ktor. Languages include Ruby, Python, Go, Swift, Kotlin, PHP and MySQL. We also build on headless CMS, Shopify and WordPress, deploy to AWS, Google Cloud or Azure, and develop REST APIs and custom integrations.
Yes. We build custom web applications, customer portals, e-commerce platforms, multi-site architectures and headless CMS deployments, along with the APIs, databases and backend systems that connect them to your CRM, marketing automation and analytics tools.
Yes. Technical SEO is implemented in the build itself: clean architecture, canonical tags, sitemaps, Core Web Vitals performance work, schema markup and structured data. For AI search (AEO, GEO and LLM SEO) we also set up llms.txt, AI-crawler access and answer-shaped content so ChatGPT, Google AI Overviews, Perplexity, Gemini and Claude can understand and cite your business. No one can guarantee citations, but the technical foundation makes them far more likely.
Performance is engineered in rather than patched on later: optimized frontend delivery, efficient backend and database queries, image and asset handling, and caching. Our targets are a sub-2-second load and strong Core Web Vitals (LCP, CLS and INP), and we verify them before launch.
Yes. We connect websites and portals to CRM platforms, marketing automation and analytics, including GA4 and tracking implementations, so leads, conversions and campaign data flow into one system instead of living in silos. For flexible, future-proof connections we also build REST APIs and Model Context Protocol (MCP) integrations, so AI assistants and agents can work with your data and tools through one standard interface.
Cost and timeline depend on scope: a marketing website, an e-commerce store and a custom web application are very different builds. Projects typically start from around $5,000. The fastest way to a firm quote is a free 30-minute discovery call, where we scope the work and recommend the right approach.
Yes. ONBOARDTECH is based in Phoenix, Arizona, and serves brands across Arizona, the United States and Latin America. We work in English and Spanish.
What is full-stack web development?
