Founder of Tech Lead Mastery | Leadership Coaching for Engineers

Atradius

When Atradius embarked on the transformative journey of bringing IT development in-house, I was entrusted with the task. Spearheading the inaugural in-house team in the Channels division was both a challenge and an honor. From hiring to setting up processes and ensuring efficient deliverables, I've fostered a culture of excellence. Today, with a mix of talent from Amsterdam to Madrid and beyond, I'm cultivating the future tech leaders of the industry. Building teams, bridging geographical gaps, and aligning with long-term goals — that's a day in my life at Atradius.

Engineering Manager

VodafoneZiggo

Reforming a dynamic team at Vodafone, I took on the mission to migrate the extensive Vodafone Enterprise Portal. From AngularJS to React and introducing NestJS middleware, our tech overhaul was comprehensive. As a Scrum Master, I introduced agile methodologies, ensuring that team dynamics were at their peak and individual performances shined. Weekly conversations with Agile Coaches and regular strategic meetings ensured we stayed ahead of challenges.

Scrum Master & Frontend Developer

Veen Bosch & Keuning Uitgevers Groep B.V.

Stepping into the vast world of the largest publisher in the Netherlands, I had my eyes set on innovation. Leading the rewrite of bookchoice.com and bruna.nl wasn't just about code; it was about crafting user experiences. Beyond projects, I had the privilege to step into the shoes of my mentor, inheriting the wisdom and challenges of being an Engineering Manager. From introducing a Scrum scoring system to spearheading remote work strategies during the COVID era, I was at the forefront of change.

Engineering Manager & Lead Frontend Developer

Harlem Next B.V.

I wore two hats: A Lead Front-end Developer and a Mentor. Crafting landing pages and dashboards with Vue.js was one part of the job; mentoring three budding engineers was where my passion truly shone. Together, we navigated the worlds of technology and soft skills, ensuring they were equipped for the challenges of tomorrow.

Lead Frontend Developer & Mentor

Joining KPN was a lesson in the power of Scrum done right. While developing in-house products, I had the opportunity to introduce innovative concepts like Feature Flag, ES6, and the BEM naming convention. It wasn't just about code; it was about improving processes and enhancing user experiences.

AngularJS Front-end Developer

comScore, Inc.

My journey abroad began with comScore in Amsterdam—a milestone that significantly amplified my professional growth. Here, I was entrusted with maintaining four intricate analytics tools, akin to giants like Google Analytics. Working with AngularJS, I delved into the complexities of constructing expansive applications that demanded efficiency and performance. Though the acquisition by Adobe marked an unforeseen chapter's end, the learning and experiences at comScore solidified my foundation in front-end technologies and large-scale application development.

JavaScript Developer

Westline Webworks Ltd

At Westline, innovation met opportunity. Entrusted with a pioneering video-based project, I dived deep into the world of HTML5 video and AngularJS. Crafting a robust app tailored for mobile and tablet users was both challenging and rewarding. Navigating through the relatively new territories of AngularJS and HTML5 video was a testament to my passion for exploring the uncharted.

Front-end developer

BIG FISH Internet Technology Ltd

Joining BIG FISH, I was promised expansive opportunities to work with JavaScript. Although we embarked on an exciting project to redesign Hungary's largest online bookstore, the nature of the role didn't align with the vision I had. Our paths diverged as I became more determined to find a role that genuinely resonated with my expertise and aspirations.

arukereso.hu

My foray into the professional IT realm began at árukereső.hu. With the burgeoning mobile era, I championed the redesign of the platform's mobile interface, working hands-on with technologies like PHP Smarty, jQuery, Less CSS, and HTML5. It was an enlightening phase, witnessing the onset of revolutionary JavaScript frameworks. However, when my aspirations leaned more towards JavaScript, I realized it was time for a new chapter.

People & Process Driven Freelance Engineering Manager | Cultivating High-Performing Dev Teams Across Borders

I’m Gábor, and I help mid- and senior-level software engineers to become impactful tech leaders.

I started my career as a web developer and, over the years, worked my way up to lead developer and then engineering manager. Along the way, I faced the same challenges many engineers encounter when stepping into leadership, such as balancing technical responsibilities with managing people, learning how to influence without authority, and making decisions that impact the bigger picture.

What made the difference for me was a mentor who helped me navigate these shifts. That experience saved me years of trial and error, and it’s why I’m so passionate about helping others who are ready to take their next big career step.

Through 1-on-1 coaching, I work with software engineers to:

👉 Prepare for leadership roles by building the right skills and mindset.
👉 Simplify the shift from coding to team leadership with actionable guidance.
👉 Overcome common hurdles like managing performance, communication, and trust.

I’ve been where you are, and I know how hard it can be to move forward when leadership feels exciting, but overwhelming. My coaching isn’t about theory—it’s about clear steps that help you grow into the leader your team needs.

If you’re a software engineer looking to take your career to the next level, let’s connect.

1) I'm a God.

2) I have no idea what I'm doing.

If you want to learn how to do better code reviews,
here are some tips for sharing feedback:


Wording makes a huge difference.

If you apply these techniques, your teammates will appreciate you.

---

❌ This is wrong
✅ This approach might cause issues with concurrent access. Why do you think about using a lock here - similar pattern in our auth service?

↳ specifc problem + solution + context

---

❌ Why didn't you just...
✅ I wonder if we could simplify this with Array.reduce()? It might be more readable for large datasets.

↳ collaborative tone + explain benefits

---

❌ This doesn't follow our standards.
✅ This doesn't match our error handling pattern. Check out our style guide section 4.2 (include link). We use the Result Pattern for such cases.

↳ specific reference + actionable guidance

---

❌ This should use the new pattern we adopted last month.
✅ This could use the new pattern we adopted last month. What do you think?

↳ doesn't give command + allow the other person to let their guard down

---

❌ nit: fix formatting
✅ Set up Prettier/ESLint and focus reviews on logic, architecture, and edge cases.

↳ automate the trivial, focus on what matters

---

Remember:
↳ Code reviews should build people up, not tear them down.
↳ Review the code, not the person!

Ultimately, the goal is to ship reliable code, not win arguments.

If a function accepts multiple parameters of the same type, 

⚠️ We may accidentally pass arguments in the wrong order. 

Types can't protect us.

Instead...

✅ Accept an object.

3 simple guidelines for better naming:

1. Classes: use nouns

❌ class MapPaymentMethod
✅ class PaymentMethodMapper

2. Functions: use verbs

❌ emailSend()
✅ sendEmail() 

3. Booleans: use adjectives

❌ active
✅ isActive

Small change → Big impact.

Is optimizing every line of code worth your time?

Over the years, I’ve worked on several React projects.

Along the way, I’ve learned some valuable lessons about performance optimization.

Not all performance issues are equal.

It’s important to focus on the ones that make the biggest difference.

I wrote an article about seven practical tips on performance optimizations in React applications.
