Boost your team's skills to avoid costly mistakes

If you're developing an e-commerce system or planning its reconstruction, you need a team that knows what they're doing. Our training, workshops and technical audits are led by practitioners: developers who design and implement advanced sales platforms daily. We share knowledge that translates into real code quality, integration stability and better collaboration between IT teams and business.

Who is this for?

For technical teams that want to avoid costly design and execution mistakes through good architecture, clear processes and proven practices.

For companies that want to increase their IT teams' independence and become independent from external suppliers – without losing quality and development pace.

For technical leaders and developers who deal with complex systems and want to make better technological decisions, improve integrations and deliver value faster.

What do we offer?
System architecture workshops
System architecture workshops

Planning a system rebuild or migration? This workshop will help you plan everything in advance – before the first line of code is written. Together we'll develop the architecture, choose the right approach (headless, microservices, modular monolith), design integrations with external systems and help you avoid typical production mistakes.

Development team mentoring
Development team mentoring

Don't need extra hands, just regular technical support for your team? We offer cyclical 1:1 or Q&A sessions weekly or bi-weekly. Often just 1-2 days (8-16h) per month is enough to remove blockers and steer the project in the right direction. We share knowledge and experience within your code environment.

Quality and performance audit
Quality and performance audit

System running too slow? Implementing new features is expensive? New bugs keep appearing consuming time and money? We'll conduct an audit of code, architecture and processes. We'll point out what's worth improving and how to do it. You'll get a clear report with recommendations that will genuinely improve system quality and team work efficiency.

We don't just teach frameworks. We teach thinking about code. We share good software design and writing practices that directly impact system quality. SOLID, automated testing (TDD, BDD), principles of readable and extensible code – all things developers often know in theory but rarely apply consciously. We train in the context of real projects, so results are visible after just a few days of team work.

From 2017 to 2024 we were official Sylius trainers – the platform behind some of Europe's most demanding e-commerce implementations. We've trained hundreds of developers and know how to tailor programs to specific team levels and needs. We conduct training on architecture, module building, external system integrations, testing and advanced techniques used in large-scale projects.

For technology leaders – CTO, CEO, owners. We help understand where your system really stands: what works, what needs changing and how to make good technological decisions. Together we'll assess possible development directions, choose technologies, estimate migration or refactoring plans, and analyze teams and suppliers. This is real strategic support in moments requiring clarity and decisiveness.

Artificial intelligence is changing how we write code – automating repetitive tasks and letting us focus on what really matters. With AI-based tools, programmers can develop systems with greater freedom. If you want your team to use these possibilities in practice – we have ready guidelines. We'll show how to effectively use coding agents like Claude Code or Junie when working with PHP and Symfony. This isn't hype – it's a real change in software development that increases productivity and job satisfaction.

Why us?

We are code craftsmen – enthusiasts of well-designed systems (SOLID, OOP patterns) and automated testing (TDD, BDD). We've trained hundreds of developers and know one thing for sure: programmers who better understand tools work more efficiently – react faster to changes, write more stable code and make decisions with confidence. We'll show your team how to achieve this.

We work on your code – everything we teach applies to real projects, not sandboxes

We teach specific skills that teams use during ongoing projects

We integrate with teams – we're technology partners, not training vendors

We know e-commerce challenges – and can respond in practice, not just theory

Working with the entire Commerce Weavers team was a pure pleasure and a dream come true for every Product Manager. They perfectly combined their business and technological experience, making them not only a partner for us but also a huge support throughout the project. I could always count on their commitment and professionalism, which translated into the final, great product - the official Tpay plugin for Sylius.

When it comes to the delivery time of new functionalities with Sylius and Symfony, Commerce Weavers are second to none. It's our third system provider for PHPers Summit and by far the best. We don't need to look any further. We've finally found a reliable long-term partner. Their commitment to the PHP community, and the high standard of service and quality of the developed application speaks for itself.

I have known Commerce Weavers guys for many years now. They've always been a big inspiration for me because of their approach to programming and openness to the open-source community. No shadow of doubt they are the most experienced Sylius trainers. As their trainee - I can totally confirm they are splendid educators who make advanced topics easy and understandable. Finally, their business culture is simply top notch. If you decide to collaborate with them - you won't only get the work done at an excellent level but will also have a lot of fun.

FAQ

Yes. Before starting collaboration we always have a brief conversation to understand team level, tech stack and specific needs. We customize programs individually – we don't do "off-the-shelf" training.

Absolutely – we actually recommend it. Working on your own repository allows immediate implementation of good practices where they're really needed. We can also work on example projects.

No. Workshops often include PMs, analysts and non-technical people – especially during architecture planning, roadmap or integration phases. What's key is that all participants understand what we're building and why.

We're available after training – we answer questions, help with more difficult implementations and offer optional support or mentoring packages. We don't end collaboration on the last day of classes.

Typical training is 1–3 days. Architecture workshops usually last 2 days. Mentoring is typically 1 day (or several hours) every 2 weeks. We adjust everything to your team's capabilities – we can split work into smaller blocks or adapt to sprints.

Yes. We often prepare mixed programs: e.g. half day architecture, half day testing; one day Symfony, second day API design. Everything depends on your real needs and team level.

Of course. Many companies start with one workshop (e.g. "E-commerce Zero") or quality audit and only then decide on mentoring or further training. You don't need to declare the entire program upfront.

No. We don't issue certificates or attestations – our goal is real impact on team work quality.
