React & Next.js Engineering
for Web Platforms & SaaS
Your React SPA ranks poorly because search engines can't crawl client-side content. Your legacy React app accumulates technical debt. Your SaaS platform fails under traffic load. We're a React development company that fixes these problems — senior engineering teams executing technical projects, not junior-heavy teams.
Why React Development Projects Fail
Most React development projects fail because teams prioritize speed over architecture. You end up with:
- SPA SEO issues: Search engines can't index client-side rendered content, killing organic traffic.
- Technical debt accumulation: Quick fixes compound into unmaintainable codebases.
- Performance bottlenecks: Apps that work in development but fail under real traffic.
- Migration disasters: React SPA → Next.js migrations that break production or take months longer than planned.
What a Competent Web Architecture Involves
A competent React development solution requires more than just knowing syntax. It requires systems thinking:
- Architecture-first approach: Design for scale, maintainability, and SEO from day one — not retrofitted later.
- Next.js for SEO-critical apps: Server-side rendering and static generation when search visibility matters.
- Senior engineers, not junior-heavy teams: Code reviews, testing, and architectural decisions made by experienced developers.
- Zero-downtime migration process: React SPA → Next.js migrations that don't break production or lose data.
Trade-off: React SPAs are faster to build initially, but Next.js requires more setup. If SEO matters, Next.js is non-negotiable.
How We Approach React Development
Architecture & Planning
We start by understanding your SEO requirements, traffic patterns, and integration needs. Then we design the architecture — Next.js for SEO-critical apps, React SPA only if search visibility doesn't matter.
Risk mitigation: Architecture decisions documented and reviewed before coding starts.
Development with Quality Gates
Senior engineers write code. Every PR reviewed by another senior engineer. Automated testing for critical paths. Performance budgets enforced.
Risk mitigation: Code quality issues caught before they reach production.
Migration Process (If Applicable)
For React SPA → Next.js migrations: We run both systems in parallel, migrate incrementally (not big-bang), test at each step, and only cut over when everything works. Rollback plan always ready.
Risk mitigation: Zero downtime, no data loss, production stays stable throughout.
This Is For Companies That:
- 01.Need React/Next.js expertise but can't hire senior engineers locally.
- 02.Have React SPAs with SEO problems that need Next.js migration.
- 03.Are building SaaS platforms that need to scale without breaking.
- 04.Want long-term dedicated React development teams, not short-term contractors.
This Is NOT For Companies That:
- 01.Need quick prototypes or MVPs with no long-term maintenance plan.
- 02.Want the cheapest possible React developers (we're senior-only, not budget shops).
- 03.Need immediate same-day turnaround (we plan, then execute).
- 04.Are looking for React tutorials or educational content (we build, not teach).
Common Objections
"Why not hire React developers locally?"
Local senior React engineers cost $150K+ in major markets and are hard to find. We execute React projects with senior engineering teams at a fraction of that cost, with timezone overlap for real-time collaboration.
Trade-off: You save on cost, but you need clear communication processes.
"What can go wrong with React development?"
Common failures: Poor SEO from SPAs, technical debt from rushed builds, migrations that break production, performance issues under load.
Prevention: Architecture-first approach, senior-only teams, code reviews.
"How do you reduce migration risk?"
We run both systems in parallel, migrate incrementally (not big-bang), test at each step, and keep a rollback plan ready. Most migrations fail because teams try to do everything at once.
Process: Parallel run → Incremental migration → Test → Validate.
What We Build

React-based dashboards with real-time data, role-based access, and responsive design.
React SPA → Next.js Migrations
Zero-downtime migrations that fix SEO issues without breaking production.
Headless CMS & Ecommerce
Next.js frontends with headless CMS backends, optimized for performance and SEO.
Why Companies Choose Yeznio for React Development
Senior-only teams: No junior engineers learning on your project. Every developer has 5+ years of React/Next.js experience.
Architecture-first approach: We design for scale and maintainability from day one, not retrofitted later.
Proven migration experience: We've migrated React SPAs to Next.js without downtime or data loss.
Direct communication: You work directly with the engineers building your app, not layers of project managers.
Long-term dedicated teams: We structure engagements for ongoing maintenance and feature development, not one-off projects.
