Web Development
Web apps designed to keep growing
We build web applications for startups and established businesses that need a partner: someone to help figure out what’s worth building, how to build it, and make sure the result solves the problem it was meant to solve.
This covers a first product that doesn’t exist yet, a system that already runs the business and needs to do more, scale further or stop breaking under its own growth, or an existing application built by another team that needs a new owner. In every case, we start with one question: what does this need to solve? Decisions about technology, scope and timeline come after that.
We build for the stage your business is at today, and design the app to take on more as you grow.

MVP & Idea Validation
MVP & Idea Validation
Fast, focused builds to test a business hypothesis with real users before committing to a full build. The goal isn't a smaller version of the final product — it's the fastest, cheapest way to get a real answer on whether the idea holds up. A clear "no" after a few weeks is a good outcome for a small budget, not a failed project.
Custom Enterprise Web Applications
Custom Enterprise Web Applications
Tailored, business-critical systems built around your specific processes rather than generic off-the-shelf software. Off-the-shelf tools are built for the average case — and enterprise workflows rarely are the average case: approval chains, legacy data formats, and compliance requirements a template wasn't built to handle. This is built to match how the business actually runs, not the other way around.
SaaS Product Development
SaaS Product Development
Multi-tenant, subscription-based platforms designed for scalability, billing, and role-based access from day one. Most of what makes a SaaS product hard isn't the first version — it's the version six months later, when a second pricing tier gets added, a large customer wants custom permissions, or usage crosses the point where a shared database starts to strain. The architecture accounts for that shape of growth from the start, not as a rewrite later.
E-Commerce & Marketplace Platforms
E-Commerce & Marketplace Platforms
Online stores and multi-vendor marketplaces with payment integration, inventory, and checkout optimization. Most revenue lost on an e-commerce platform doesn't happen from a bug — it happens in the checkout flow, a delayed inventory sync, or a payment step that adds friction at exactly the moment someone was ready to buy. Built and tuned around where that friction actually shows up.
Progressive Web Apps (PWA)
Progressive Web Apps (PWA)
App-like, installable web experiences with offline support, without the app store overhead. A native app earns its cost when it needs deep device integration or store discovery genuinely matters — a lot of products need neither, and pay for two codebases and two review processes anyway. A PWA gets the installable, offline-capable experience without that overhead when the product doesn't actually need it.
UI/UX Design
UI/UX Design
Wireframes, prototypes, and interface design grounded in how people actually use the product, not just how it's meant to look in a mockup. Most usability problems don't show up in a design review — they show up after launch, in a support ticket about a button nobody could find, or a drop-off at exactly the step that looked obvious on paper. Design gets tested against real use before it ships, not just approved on how it looks.
Legacy Modernization & Refactoring
Legacy Modernization & Refactoring
Untangling monolithic or outdated codebases and paying down technical debt without disrupting the live product. A full rewrite is rarely the real option — the system is usually running the business while it needs to change, so the risk isn't in the new code, it's in the migration path. Modernization happens in stages the business can absorb, old and new running side by side until the cutover is safe.
Web Performance & Scalability Optimization
Web Performance & Scalability Optimization
Auditing and re-architecting existing applications for speed, load handling, and infrastructure cost. Slowdowns rarely show up where they started — a query that got slow months ago surfaces today as a support ticket about page load, or a bill that's crept up without traffic actually changing. The audit traces the symptom back to its real source before anything gets re-architected.
Ongoing Development & Infrastructure Support
Ongoing Development & Infrastructure Support
Taking over an application someone else built — codebase, deployments, and all — to keep shipping features and keep the infrastructure running, instead of leaving it frozen because nobody wants to touch code they didn't write. Most teams inherit an app with no documentation and the developer who built it long gone, so the real risk isn't the next bug — it's not knowing what breaks if a piece of it does. We start with an audit of what's actually running, then take over development and infrastructure as one continuous responsibility, not a handoff with gaps in between.

Approach
How we make it happen
Discovery, architecture, and iteration, sequenced so nothing about scope or timeline is a surprise halfway through.
Discovery & Requirements
Stakeholder interviews with everyone who actually touches the product, a technical audit of any existing system, and a written scope with concrete success metrics — settled before a single line of code gets written, not discovered mid-sprint. Why it matters: skipping this is the single most common reason web projects blow their budget — not bad code, misaligned scope.
step 01
Architecture & Tech Stack Selection
Chosen for your team's long-term maintainability and hiring market — not for what's trending this year — weighing what it costs to run and how easy it is to hire for, at the scale you're actually planning for. Why it matters: the stack has to still make sense to whoever's maintaining this after we're gone.
step 02
UX/UI Prototyping
Wireframes and clickable prototypes for the core flows first, validated with real users or stakeholders before full-scale build begins — so a flow that sounds obvious in a meeting gets tested before it's built. Why it matters: catching a misunderstanding in a prototype costs an hour; catching it in production costs a sprint.
step 03
Agile Development Sprints
Short, 1–2 weeks sprints, with a working build to click through from the first 2–3 weeks — not slides — and a real conversation after every sprint about what's next. Why it matters: you get to redirect after two weeks of real feedback, not after six months of assumptions.
step 04
QA & Testing
Automated tests, manual QA, and security review run continuously through development — including edge cases and failure paths, not just the happy path a demo would show. Why it matters: a demo hides different problems than production does — this is where those get caught before your users do.
step 05
Deployment & Launch
CI/CD-driven releases, staged rollouts, and monitoring configured before go-live, with a rollback plan ready — not assumed — so the team already knows what normal looks like when real traffic hits. Why it matters: a deploy should be a non-event, not an adrenaline spike.
step 06
Post-Launch Support & Iteration
Bug fixes and new features prioritized by what analytics and support tickets actually show — where people drop off, what nobody uses, what generates complaints — not by internal opinion, reviewed on a regular cadence. Why it matters: a guess about what to build next is still a guess, even from someone who knows the product well. Data settles the argument before it starts.
