Web Development Services
Next.js applications and marketing sites engineered to be fast, with performance budgets enforced in CI, not promised in proposals.
Who this is for
The situations that bring people to us
Your site is slow, and slow sites lose rankings and trust
Core Web Vitals are a ranking input and a first impression. A site that takes four seconds to paint is marketing against itself.
The frontend can't keep up with the product
Legacy frontends make every feature expensive. A modern React and Next.js foundation with a component system changes the slope of every future sprint.
AI features need AI-native UX
Streaming responses, optimistic states, and graceful failure are their own frontend discipline. Bolting a spinner onto a chat call is where AI products feel cheap.
What we build
Concrete deliverables, not categories
Next.js applications
Full application frontends (dashboards, portals, product UIs) on the App Router, typed end to end, with the state and data patterns that stay maintainable.
High-performance marketing sites
Static-first sites with technical SEO built in and Core Web Vitals budgets enforced in CI.
▸ You are reading one; this site is built to its own published budgets
Frontends for AI products
Streaming UX, token-by-token rendering, optimistic and fallback states: the interface layer that makes AI features feel engineered.
Design systems & component libraries
Tokenized component systems with Storybook, so every future page is assembled rather than reinvented.
How it works
Why our sites are fast on purpose
Fast sites are an architecture, not an optimization pass. Pages are statically generated so the network serves finished HTML; images, fonts, and scripts live inside explicit budgets; and third-party code is treated as the hazard it is: loaded late, or not at all.
The loop is what keeps it true: real-user vitals feed dashboards, and Lighthouse budgets run in CI, so a performance regression fails a pull request instead of greeting a visitor. We hold this site to the same regime, which is the least a web vendor owes you.
Proof, not promises
RocketJob: a content platform built for speed and SEO
A client's public content surface: a Next.js blog and content system engineered for search from the schema up, running in production with analytics wired to publishing decisions.
How we work
Four steps, each with an artifact
Artifacts beat adjectives. Every step of an engagement ends in something you can hold us to.
Step 1
Scoping call
→ Written scope & estimate
Thirty minutes on what you are building and why. You leave with a written scope, an honest estimate, and our view on whether AI is even the right tool.
Step 2
Architecture sprint
→ System design document
We design the system before we bill for building it: data flows, model choices, failure modes, and the success measure we will be judged against.
Step 3
Build in weekly demos
→ Working software, week one
Short cycles, working software every week, and decisions made in the open. You see progress in the product, not in status reports.
Step 4
Launch & run
→ Monitoring, evals & handover
We ship it, instrument it, and either run it with you or hand it over with documentation your team can actually operate from.
Site builds are quoted from a page-by-page specification with performance budgets written into the scope. If we miss the agreed lab budgets at handover, we fix it on our time. That is what a budget means.
Stack for this work
Straight answers
Questions buyers actually ask
Why Next.js specifically?
Because it lets one codebase serve finished, crawlable HTML (which search engines and AI systems reward) while remaining a full React application for product work. Static generation, image and font optimization, and metadata handling come from the framework instead of a plugin pile. It is also the stack our own products run on daily.
Do you guarantee Core Web Vitals?
We contract lab budgets (typically LCP under 2.0 seconds and CLS under 0.05 on a throttled mobile profile) and enforce them in CI so regressions cannot merge. Field results also depend on your third-party scripts and content discipline after handover, so we document exactly what protects the numbers.
Do we need a CMS?
Only if non-developers must publish frequently. Git-based MDX content is faster, safer, and free, and it is where we start most builds; we add a headless CMS when the editorial workflow genuinely demands it, not by default. The honest question is who edits, how often. We will ask it in scoping.
Is SEO included?
Technical SEO is not an add-on here: semantic structure, metadata, schema, sitemaps, and performance ship as part of the build, because a site without them is unfinished. Ongoing content strategy and AI-search optimization are available as separate, honestly-scoped work.
What does a marketing site build cost?
A focused, high-performance site of ten to fifteen pages typically lands in the low five figures (USD), driven by page count, custom design depth, and content readiness. Application frontends are scoped from the design system and feature map rather than page count.
