The best developers I know have one thing in common: they optimize for learning speed, not coding speed. They choose boring, proven technologies over shiny new ones. They write documentation. They ask questions. They admit when they don't know something.

How to learn web development on weekends:

• Build projects, don't collect tutorials
• Pick one technology stack and go deep
• Deploy something every weekend
• Document your learning publicly

Consistency beats intensity every time.

[Tuomo Kankaanpää @tumee]

Side projects push you to handle real deployment, user feedback, performance problems, and ongoing maintenance. Each obstacle becomes valuable experience you won’t find in tutorials.

[Tuomo Kankaanpää @tumee]

Developer-founders who dedicate a significant portion of their time to non-technical work are much more likely to create profitable products. Understanding customers is essential for success. While you can hire developers, finding market fit requires your own involvement.

[Tuomo Kankaanpää @tumee]

Junior developers:
• Focus on writing more code
• Learn new frameworks constantly
• Measure success by features shipped

Senior developers:
• Focus on deleting unnecessary code
• Master fundamentals deeply
• Measure success by problems solved

Experience changes perspective.

[Tuomo Kankaanpää @tumee]

How to advance beyond senior developer:

• Translate technical decisions into business impact
• Mentor other developers consistently
• Lead architecture discussions with stakeholders
• Take ownership of cross-team problems
• Communicate complex concepts simply

Technical skills get you hired. Leadership skills get you promoted.

Bad developers:
• Copy-paste without understanding
• Write code first, ask questions later
• Avoid documentation

Good developers:
• Understand before implementing
• Plan architecture before coding
• Document while building

Choose your approach wisely.

Web development tutorials focus on building features, while real projects require you to maintain them over time. Knowing React means more than understanding syntax; it involves handling the challenges that come with scaling your app to 100,000 users.

[Tuomo Kankaanpää @tumee]

React components that re-render unnecessarily kill app performance:

• Move expensive calculations to useMemo
• Split components by data needs, not UI layout
• Use React.memo for components that receive same props often
• Keep render functions fast and predictable

Your users notice every unnecessary millisecond.

[Tuomo Kankaanpää @tumee]

Learning new frameworks is useful, but the developers who move ahead are those who use technology to solve real business problems. Focus on making an impact with your skills, not just adding tools to your resume.

4 steps to convince your team to go headless:

1. Show them the performance benchmarks
2. Demo the developer experience improvements
3. Calculate the hosting cost savings
4. Present 3 real competitor sites using it

Then watch the "when can we start?" questions begin.

[Tuomo Kankaanpää @tumee]

The best developers stopped choosing between content management and performance years ago. Headless CMS gives you both. Your content team gets their familiar editing interface, you get your React components and API flexibility. It's a win win for everyone.

[Tuomo Kankaanpää @tumee]

Benefits of going headless:

- Deploy to CDNs globally
- Use any frontend framework
- Scale content and presentation independently
- Faster page load speeds
- Better security posture
- Multi-channel content delivery

[Tuomo Kankaanpää @tumee]

Traditional CMS:

Coupled frontend/backend
Template-based theming
Server-side rendering limits

Headless CMS:

API-first architecture
Framework flexibility
Edge deployment ready

Choose your stack wisely.

[Tuomo Kankaanpää @tumee]

Is it normal to get stuck on a basic coding problem for hours?

Yep.

Coding requires a lot of thinking and sometimes things that feel "basic" end up being super difficult. You just need to work your way through the problem and take the time for it.

That's part of the job.

I've been a software developer 10+ years.

These are the 4 lessons I've learned from my past mistakes:

1. Don't ignore automated testing
2. Clear communication & teamwork are key to success
3. Avoid technical unnecessary debt at all cost
4. Learn from failures, they're ok

[Tuomo Kankaanpää @tumee]

Things you want to consider when choosing a RTE editor for your project:

- Maintainability
- Extensibility
- Ease of use / UX
- Data output options
- Separation of representation & data

Consider your use-case and evaluate it through these lenses to make the correct choice.

[Tuomo Kankaanpää @tumee]

Web development involves much more than writing code.

For example:
- planning
- designing
- debugging
- testing
- understanding UX
- communication
- teamwork

We often give too much emphasis on writing code, when it is just a fraction of what web developers do.
