Hello! I am Ivan Ponamarev.

Senior Full-Stack Developer & Modernization Expert

I build lightning-fast, scalable web interfaces and search-driven platforms. My passion is taking heavy, legacy e-commerce systems and turning them into modern Headless applications without breaking the business.

Pragmatic Engineering Over Blind Hype

I have over 10 years of experience in full-stack development. While many developers want to rewrite everything from scratch, I focus on what actually works for the business. I specialize in bridging the gap between reliable, money-making legacy backends (PHP / 1C-Bitrix / Laravel) and modern, fast frontends (Next.js). I design architectures that survive traffic spikes, utilize Elasticsearch for instant data delivery, and keep SEO rankings safe during migrations. I don't just write code — I take ownership of technical decisions and long-term scalability.

Case Study

How do you make a heavy monolithic store fly? Recently, I decoupled a massive 1C-Bitrix store with 28,000 products and complex regional logic. By keeping the stable PHP backend and building a Next.js + Elasticsearch frontend layer, we achieved instant filtering and navigation while preserving 100% of the SEO structure. No risky big-bang rewrites, just smart headless architecture.

I use the best tools to solve complex problems across the full stack:

Core:

PHP (1C-Bitrix, Laravel) • JavaScript ES6+ / TypeScript • Next.js • React • Vue

Data & Search:
