Enterprise web projects fail for the same predictable reasons: development starts before architecture is clear, technology is chosen based on team familiarity rather than requirements, security and performance are addressed after the build rather than during it, and contractors deliver functional code that is unreadable, untested, and impossible to maintain. Full On Consulting's web development consulting practice delivers custom web application development, React development, Next.js consulting, eCommerce web development, API development, and legacy web application modernization — with Fortune 100 delivery experience and a senior-only staffing model that means the team you meet is the team that builds your application.

Our Web Development Services
From Architecture and Strategy to Scalable Production Applications
Web Strategy & Architecture
Technology selection, architecture design, and a delivery roadmap based on your requirements — not on our preferred stack. Not sure whether React, Next.js, a Jamstack approach, or a traditional full stack is right for your use case? Our architects conduct an objective assessment and deliver a recommendation you can act on.
Custom Web Application Development
End-to-end custom web application development — new builds and platform replacements using React, Next.js, Node.js, Java, .NET, and Spring. Front end through back end, deployed to your cloud environment of choice. Fortune 100 delivery experience applied to every engagement regardless of scale.
eCommerce Web Development
Scalable, high-performance eCommerce platforms built for enterprise transaction volumes — storefront development, checkout optimization, payment integration, inventory systems, and progressive web app experiences that perform on any device. Revenue-generating at launch, not after months of post-launch stabilization.
API & Integration Development
API development consulting covering RESTful and GraphQL API design and implementation, microservices architecture, and back-end integration layers that connect your web applications to enterprise systems, third-party platforms, and data sources. Built for performance, security, observability, and the scale your business requires.
Web Modernization & Legacy Migration
Legacy web application modernization — assessing your existing application landscape, defining a modernization roadmap that sequences work by business impact, and executing the migration to modern architecture with the minimum disruption possible. Reduce technical debt, improve performance, and restore your team's ability to ship new features at speed.
Staff Augmentation & Project Delivery
Senior web developers, architects, and full stack engineers ready to embed in your team or lead full project delivery. Whether you need to supplement your internal team with senior resources on an active build or have Full On Consulting execute your web project end-to-end — we staff every engagement with senior practitioners only.
What Makes Us Different
Why Our Web Applications Perform, Scale, and Last
Architecture-First Approach
We define the architecture, technology stack, and delivery plan before writing a line of production code. Web projects that begin development before architecture is clear accumulate technical debt from the first sprint — and pay for it in every release that follows.
Fortune 100 Full Stack Experience
We have delivered enterprise web applications for Fortune 100 companies — applications at a scale and complexity that most development firms never encounter. That experience shapes how we design for performance, security, and maintainability from the start.
Technology-Agnostic Recommendations
We are not committed to any framework, platform, or vendor stack. We recommend the technology that fits your requirements, your team's capabilities, and your long-term architecture direction — not the one that is most familiar to us or most profitable to implement.
Senior Practitioners, No Junior Staffing
No junior developers. No bait-and-switch. Every web engagement is staffed with senior developers and architects who write production-quality code, document their work, and stay accountable through go-live and beyond.
Featured Case Study
Jamstack Migration — 10x Performance, 30% Hosting Cost Reduction
Full On Consulting executed a full platform migration from a legacy server-rendered architecture to a modern Jamstack implementation — delivering a 10x improvement in page load performance and a 30% reduction in hosting costs. The engagement demonstrates our ability to modernize legacy web platforms with measurable, quantified outcomes rather than speculative performance claims — and to execute a complex migration with zero data loss and minimal business disruption.
A broader IT transformation engagement demonstrated the same delivery discipline at enterprise scale — delivering $40M in documented savings while managing technology modernization across 90+ global facilities. The same architectural rigor and senior-only staffing model that produces individual project results produces enterprise transformation outcomes.

Before You Engage
What to Ask a Web Development Consulting Firm
Do they conduct architecture planning before development begins?
Web projects that begin development before architecture is clear accumulate technical debt from the first sprint. Every feature added without a clear architectural foundation makes the next feature more expensive and the next sprint slower. Ask whether the firm conducts a structured discovery and architecture planning phase — defining the technology stack, system design, integration points, and non-functional requirements — before writing any production code. The firms that skip this step save time in week one and pay for it in every week that follows.
How do they approach legacy web application modernization?
Legacy modernization is one of the highest-risk categories in web development. Organizations that attempt 'big bang' rewrites — replacing everything at once — frequently abandon the effort partway through, having accumulated both the cost of the rewrite and the ongoing cost of maintaining the legacy system. Ask how the firm sequences modernization, how they manage the transition period when both systems must operate in parallel, and what their track record looks like on legacy modernizations that actually reached completion without exceeding budget.
How do they handle web performance and Core Web Vitals?
Web performance affects both search ranking (Google uses Core Web Vitals as a ranking signal) and user retention (users abandon slow pages in seconds). Ask whether performance is designed into the architecture from the start or optimized after the fact. Retrofitting performance into a completed application is significantly more expensive than building for performance from the beginning. Ask specifically how the firm approaches LCP, FID, and CLS during development — not as a final optimization pass, but as ongoing design criteria.
What is their approach to long-term web application maintenance?
Web applications require ongoing maintenance — dependency updates, security patches, browser compatibility, and feature evolution. Organizations that treat web development as a one-time project consistently underestimate the total cost of ownership and end up with applications that degrade over time without a clear owner. Ask how the firm structures post-launch support, what the process looks like for transferring institutional knowledge about the application architecture to your internal team, and what options exist for ongoing maintenance if your internal team doesn't have the bandwidth to own it.
