[Lucas Magliari @l_magliari]

I'm an Analytics Engineer with 5+ years of experience working with data. I love AI, technology, and turning ideas into real products and businesses.

I'm passionate about making things happen, bringing ideas to life, and building solutions that solve real problems. And I'm just getting started!

Here, I share what I learn about data, AI, development, and my journey building in public.

As someone learning chess, I struggled to find a tool that could help me understand my mistakes and actually improve. That's why I built:

https://t.co/YR4w3IpGOm.

The idea was simple: turn real games into personalized training, with clear, practical explanations instead of just engine evaluations.

I have plenty more ideas I want to bring to life, and I'll be sharing the journey here.

If you're into tech, AI, building products, or entrepreneurship, let's connect and share ideas!

Seria difícil, não iam entender as possibilidades e como funciona.

Bizarro o quanto evoluímos em pouco tempo

imagine going back to 2019 and trying to explain opus 5.5 to someone

♟️ I built https://t.co/YR4w3IqeDU because I wanted a better way to learn from my own chess mistakes. Now I’m turning that idea into a real product!

If you’re building something too, let’s connect and grow together! 🤝

@vlasyuk_a @X Thanks, Alex! I’m planning to put more of my data skills to use as I keep improving Deblunder

[Lucas Magliari @l_magliari]

@DanielSmidstrup @X Cool! Give it a try

[Lucas Magliari @l_magliari]

@DigialiTay @X Nice! The idea is to help us, give https://t.co/EgrUfR71Al a try

[Lucas Magliari @l_magliari]

@steviee_dev @X Cool, mate! Give https://t.co/EgrUfR71Al a try

[Lucas Magliari @l_magliari]

@somehowali @X I have a lot of ideas too

[Lucas Magliari @l_magliari]

@liechti_dev @X Boa Noite daqui, Koru looks very cool!

[Lucas Magliari @l_magliari]

@KyleWang1087922 @X Cool, could you share more?

[Lucas Magliari @l_magliari]

@leononrails @X Nice, what are you working on?

[Lucas Magliari @l_magliari]

@Worshipperfx @X Cool, different!

[Lucas Magliari @l_magliari]

@SimoneWanghrxg @X Very interesting! I just sent you a DM

[Lucas Magliari @l_magliari]

@Worshipperfx @X Hey, what are you building?

[Lucas Magliari @l_magliari]

@SimoneWanghrxg @X Hey Simone! Great to connect with you too!

What are you building?

[Lucas Magliari @l_magliari]

I'd say market research is a good start. Look for competitors and see if people are already paying for similar solutions. That's usually a good sign there's demand.

I'm still figuring it out myself! I built https://t.co/JaH6ODNERr to solve a problem I had, and now I'm working on getting real users and feedback.

How about you?

@opapodeprompt Boa dica! Já fiz alguns testes no PC também, mas ainda preciso explorar melhor esses estados e o comportamento com o teclado aberto no mobile. Vou incluir isso nos próximos protótipos. Valeu!

[Lucas Magliari @l_magliari]

Uma coisa que tem acelerado muito meu desenvolvimento com IA: Prototipar as telas antes de codar. É uma dica básica, mas talvez algumas pessoas não utilizem.

Fui adaptar o Deblunder para mobile e aproveitei para repensar algumas telas, buscando uma melhor experiência do usuário.

Usei o Claude Code + Artifacts para experimentar layouts e fluxos sem precisar implementar tudo de primeira.

Curtiram a direção? Como vocês fazem do lado de vocês?
