OUR SERVICES

Four ways we make Next.js work better

Specialized Next.js expertise across four practice areas, each designed to turn performance into sustained revenue.

AI Engineering

Every Blazity engagement already runs on AI agents — code generation, testing, PR reviews, documentation. It's how we deliver 4x velocity and 70% performance gains in months, not years. Now we package the same agent workflows for our clients' engineering teams. You get production-grade agents built into your actual development lifecycle.

Performance Engineering

Your site is slow, failing Core Web Vitals, and losing revenue with every second of load time. We diagnose the root cause and fix it, delivering measurable performance gains that sustain for 18+ months.

Migration & Modernization

You are stuck on legacy technology that slows development and blocks growth. We migrate you to Next.js with zero downtime so your team ships faster, your platform scales, and revenue-generating features reach market sooner.

AI enGINEERING

We build with AI agents. We build them for you too.

Every Blazity engagement runs on AI agents — code generation, testing, PR reviews, documentation. We package the same workflows for our clients' teams so they ship faster long after we leave.

PERFORMANCE ENGINEERING

Slow applications lose revenue. We make and keep them fast.

Rendering & Caching Optimization

Inconsistent SSR/SSG/CSR setup and broken cache invalidation are the root cause of most performance issues. We fix the rendering layer so improvements stick across releases.

CONSULTING

Get clarity before committing to a major initiative.

Major initiatives require proof before commitment. Our consulting engagements (1–4 weeks) diagnose problems, quantify technical debt, and build the business case so you move forward with confidence, not assumptions. Every consulting engagement leads to a clear recommendation with ROI projections your leadership team can act on.
