You will get your Next.js build errors fixed and deployed to Vercel
Project details
Is your Next.js app failing to build or breaking on Vercel? Cryptic build logs, hydration bugs, TypeScript compilation errors, or misconfigured environment variables can instantly stall your launch.
I am a Senior Full-Stack Engineer specializing in Next.js, Node.js, and cloud deployments. I will quickly diagnose the exact root cause of your build failure and deliver a stable, production-ready deployment.
Common issues I resolve:
• Vercel Deployment Failures (serverless timeouts, bundle size issues)
• SSR & Hydration Errors ("Text content does not match server-rendered HTML")
• TypeScript compilation & dynamic export errors
• Window/localStorage errors in Server Components
• Environment variables (.env) & API key misconfigurations
• Broken GitHub to Vercel CI/CD pipelines
• Package manager dependency conflicts (npm/pnpm/yarn)
What you will receive:
• A clean, error-free Next.js production build
• Fully tested, live deployment on Vercel
• Organized GitHub repository with working CI/CD triggers
• Clear explanation of the bug and steps to prevent it
Send over your repo or error logs, and let's get your project live today! Live example: saas.shlykoff.com.

About Vasilii
Full stack Software Engineer
Tbilisi, Georgia - 4:01 am local time
Over the years I've built backend systems, databases, and APIs across a range of setups: REST and GraphQL APIs, microservices and distributed systems, cloud infrastructure, and containerized deployments (Docker). On the frontend, I work primarily with Next.js and Vercel. I also handle two areas that tend to break in production if done carelessly: payment systems (Stripe — Checkout, subscriptions, webhook handling) and database security (PostgreSQL/Supabase Row Level Security, multi-tenant data isolation). More recently I've been adding OpenAI/LLM integrations into existing products for teams adding AI features.
Recent example: I built and shipped a full SaaS application end-to-end — authentication, org-based RLS, Stripe subscriptions, gated features, deployed live — to demonstrate how these pieces fit together in one working product. Demo and source code are in my portfolio below.
Before Upwork, I co-founded and served as CTO at MySoft, leading architecture, technical strategy, and delivery for custom backend systems and infrastructure across multiple industries. I started programming in international ACM competitive programming olympiads, which is where the habit of writing precise, well-tested code came from.
Whether it's a backend API, a database/RLS issue, a broken Stripe integration, a Next.js deployment problem, or wiring an LLM into your product — send me the details and I'll tell you honestly whether I can help and how long it'll take.
