What Is Full Stack Web Development?
Full stack web development is the practice of designing and building both the front end (what users see) and the back end (servers, databases, and logic) of a website or web application — plus the integrations, hosting, and maintenance around it. A full stack team owns the entire build end to end, so one partner is accountable for how the whole thing performs.
At Elevarus, full stack web development services cover everything from a marketing website to a custom web application: design, front-end and back-end engineering, database work, third-party integrations, and ongoing performance and hosting. It is one of several growth services we offer — see the full range on our services page.
Websites and Software That Perform
We design and build the whole thing. Websites, landing pages, web apps, and custom software, end to end. Design, front end, and back end under one roof, so nothing gets lost in the handoff. We are a performance company first, which means we build for speed and conversion, not just a good-looking homepage. You get a site that loads fast, ranks, and turns visitors into action, shipped without the bloated agency timeline.
What We Build
Custom Websites
Your site is the first thing buyers judge you on. We design and build custom websites from the ground up, structured for the way real visitors move and the way Google reads pages. Clean information architecture, fast load, responsive on every device, and copy and layout aimed at the action you want. No templates pulled off a shelf and bent to fit. You get a site built around your business, your offer, and your conversion goals.
Conversion-Ready Landing Pages
A landing page has one job: turn paid clicks into action. We build pages for paid traffic and tune them with CRO in mind, so the spend you put behind them actually pays back. Tight message match between ad and page, a clear single offer, fast load, and forms and CTAs placed where they convert. Built to test, so you can run variants and let the data pick the winner instead of guessing.
Web Applications & Custom Software
When an off-the-shelf tool does not fit how you work, we build the software that does. Customer portals, internal dashboards, admin panels, and line-of-business tools, built on a modern stack with real authentication, roles, and data you can trust. We start from your workflow, not a generic feature list. You get software that fits the way your team actually operates and scales as you grow.
Integrations & APIs
Your tools should talk to each other. We connect your CRM, analytics, payments, marketing platforms, and the rest of your stack so data moves automatically instead of through copy and paste. We build and consume APIs, wire up webhooks, and sync systems that were never meant to work together. The result is one connected stack, accurate reporting, and a lot fewer manual steps.
Performance, Hosting & Maintenance
A site that is slow or down is costing you. We optimize for Core Web Vitals and real load speed, harden security, and host on infrastructure built to stay up. After launch we keep it healthy with monitoring, updates, backups, and uptime you can count on. You ship fast, then you stay fast, without babysitting it yourself.
Full Stack Agency vs. Freelancer vs. In-House: How to Choose
Not sure how to source your build? Here is how the common options compare on the factors that decide whether a web project ships, performs, and stays yours.
| Approach | Front + back end | Integrations & APIs | Code ownership | Speed to launch | Accountability |
|---|---|---|---|---|---|
| Full stack agency (Elevarus) | One team covers both | CRM, ERP, payment & marketing APIs | You own all code & accounts | AI-accelerated, faster than a traditional shop | One partner owns the whole build |
| Individual freelancer | Often front-end OR back-end | Varies by the person | Usually yours, if scoped | Depends on their availability | Single point of failure |
| In-house hire | Broad, but limited by headcount | Whatever your team can staff | You own it | Limited by hiring & ramp time | High, but scarce and costly |
| DIY / no-code builder | Front-end templates only | Plugin-limited | Locked to the platform | Fast to start, hard to scale | You carry the risk |

AI-Accelerated Design and Development
We do not just talk about AI, we build with it every day. Our design and engineering run on agentic AI tooling we built ourselves, the same kind of systems we deploy for clients, so we ship faster than a traditional shop. That means modern engineering and a tight timeline at the same time, instead of choosing between the two.
How We Build: Our Full Stack Development Process
A clear, repeatable path from idea to a live, owned, high-performing build.
Discovery & Scope
We map what you are building, who it is for, and how success is measured, then scope the timeline up front.
Design
We design the interface in Figma so you see and approve the experience before we write a line of code.
Build
Our engineers build the front end, back end, and database together, accelerated by the agentic AI tooling we built in-house.
Integrate & Test
We connect your CRM, ERP, payment, and marketing tools, then test for performance, security, and quality before anything ships.
Launch & Maintain
We launch, hand over full ownership of the code and accounts, and can keep it fast, secure, and up to date afterward.
Real Client Results
A look at full stack builds we have shipped for real clients — the work, in their own case studies.
Apposite Technologies
For Apposite Technologies, a global network-testing supplier, we designed a new website in Figma and shipped it as a custom WordPress build that reflected their brand — then wired in full stack integrations across Salesforce, Pardot, Marketo, and their Epicor ERP, plus custom reporting dashboards.

For Ameriside, a home-remodeling contractor, we built custom landing pages and sales funnels integrated directly into their CRM and ERP (Marketsharp), with call tracking wired in for real-time lead and sales visibility.

Frequently Asked Questions
What do you actually build?
Custom websites, landing pages built for paid traffic, web applications, and custom software. That covers design, front end, and back end, plus the integrations and hosting around it. If it lives on the web and has to perform, we build it.
Do I own the code and the site?
Yes. You own the code, the site, the design, and the accounts it runs on. We build it for you and hand over full control, including the repository and any credentials. You are never locked into us to keep it running.
What stack and CMS do you use?
We pick the stack that fits the project instead of forcing one toolset on every client. That ranges from a managed CMS for content-heavy sites to a modern app framework with a real database and APIs for software. We build on proven, well-supported technology, so your site is fast, secure, and easy for any developer to maintain later.
How does AI speed things up, and does quality suffer?
We use agentic AI tooling we built ourselves to handle the repetitive parts of design and development, which cuts the timeline below a traditional agency. Quality goes up, not down, because every build still goes through human engineering review, testing, and our performance and security standards. The AI does the grunt work so our people spend their time on the parts that need judgment.
How fast can you ship, and what does the timeline look like?
Faster than a traditional agency, because our AI-accelerated process removes the slow handoffs that drag most projects out. A focused landing page moves quickly, while a full custom application takes longer depending on scope. We scope your timeline up front in the consultation so you know what to expect before we start.
