Why Work With Me

Developer portrait
(about me)

I'm a full-stack developer with 6+ years of experience helping founders and businesses turn ideas into production-ready web applications. I work primarily with Next.js, React, Node.js, NestJS, and PostgreSQL, building everything from fast MVPs to full-scale SaaS platforms.

Most of my work is freelance, which means I've shipped across a lot of different products and industries — and learned what actually matters: clean architecture, reliable delivery, and code that's still maintainable a year later. I care as much about the product decisions as the technical ones, so the things I build are meant to grow with you, not get rebuilt from scratch.

40+Projects shipped

From MVPs to full-scale web applications.

35+Clients served

6+Years Experience

Building fast, scalable products since 2020.

Don’t Take My Word For It

(Testimonials)

Here’s what clients say about our collaboration and the impact of the projects we’ve built together.

01 / 00
Alex built a complex, content-driven platform from scratch—front to back—bringing to life an ambitious vision that required both technical precision and creative insight. He developed custom metadata filtering, dynamic caching, editorial tools, API integrations, and a refined user experience, all tailored to a highly specialized use case. Beyond his technical expertise, what truly sets Alex apart is his imagination, clarity of thought, and problem-solving mindset. He consistently went far beyond expectations, always treating the project as if it were his own.
Valery

Founder

UPWORK
Alexander does superb work! He is reliable, consistent and finds solutions to even the most challenging problems. I cannot recommend him highly enough. Your project will be in good hands with him no matter how complex it may be.
Lucjan

Founder

UPWORK
Alexander is highly experienced in website development and very creative in meeting our needs. He is very talented, understands the needs of different markets, and has a strong grasp of ecommerce process flow management. I recommend him to anyone looking to develop a website for any purpose.
Arsany

CEO

UPWORK
I came to Alexander with nothing but a rough sketch and a desperate need to launch before our competitor. Within 10 weeks, he delivered a fully functional, multi-tenant SaaS platform with Stripe billing, user roles, and a sleek dashboard. What impressed me most was how he handled the entire stack — from the responsive Next.js frontend to the NestJS backend with PostgreSQL. He even suggested a few AI features we hadn't considered, which became our biggest selling point. He's not just a developer; he's a product strategist who genuinely cares about your success.
Sarah

Founder

We needed an AI-powered chatbot for our e-commerce platform that could handle complex product recommendations and order tracking. Alexander built an incredible solution using OpenAI and a custom RAG pipeline that integrates seamlessly with our Shopify storefront. The chatbot is fast, accurate, and has already increased our conversion rate by 18%. Beyond the technical execution, I appreciated how he explained everything in plain English — no jargon, no mystery. He made a complex AI integration feel simple and accessible.
Marcus

CEO

LinkedIn
Our legacy system was slow, buggy, and costing us clients. Alexander rebuilt our entire platform from scratch using Next.js and Node.js, and the transformation was night and day. He also integrated a RAG-powered AI assistant that handles 70% of our customer support queries automatically. The performance improvements were incredible — our site now loads in under 1.5 seconds even with heavy traffic. On top of his technical skills, his communication was flawless. He kept us updated daily and delivered ahead of schedule every single time.
James

CTO

LinkedIn
Alexander took our outdated, slow website and turned it into a modern platform that our customers actually enjoy using. He added an AI search feature that our users love, and our server costs dropped significantly thanks to his optimization work. He kept us updated daily and made the whole process smooth and stress-free. We'll definitely work with him again.
Rachel

COO

LinkedIn
Alex built a real-time dashboard for our team that shows live data and updates instantly. It used to take us hours to generate reports, and now we see everything at a glance. He was responsive, delivered on time, and actually listened to what we needed instead of just building what he thought was cool. A great experience from start to finish.
