Freelancer profile translated to English.

Description

Software architect & former CTO, I help startups and technical teams modernize, optimize, and scale their web applications.

I focus on architecture, performance, and scalability challenges: technical audits, legacy stack migrations, progressive refactoring, SQL/backend optimization, technology choices, and improving developer experience.

My approach: evolve products without unnecessary rewrites. I favor controlled migrations, simple architectures, and targeted optimizations that deliver concrete impact.

I have supported projects at various stages:

• Migrating existing applications to modern stacks

• Auditing and optimizing application performance

• Analyzing and improving complex SQL queries

• Refactoring and simplifying technical architectures

• Creating MVPs and web applications from scratch

• Implementing best development practices

Formerly CTO of Station, I led the technical evolution of a complex Open Source product based on modern web technologies.

I now contribute to the Vite.js Open Source ecosystem, working on advanced topics: JavaScript frameworks, SSR, tooling, universal deployment, multi-runtime compatibility, and developer experience.

Types of engagements:

• Technical audit & roadmap for evolution

• Legacy → modern stack migration

• Performance optimization (SQL, backend, frontend)

• CTO / Lead Tech consulting

• Frontend & backend architecture

Core Stack: TypeScript, React, Node.js, Vite, Vike, SQL, GraphQL, Electron.

Is your application slowing down, your stack becoming hard to maintain, or are you planning a major technical evolution? I can help you define the right path.
