Building delightful products ✨

[Luis Castillo @LukoCastillo]

One of the hardest part of building a product from scratch?

Getting lost in the 'unknown unknowns', the things you don't know that you don't know.

I’m significantly older than you. I started coding in the late 60s. My current strategy is to not read any of the code written by my agents. That’s the only way I can take advantage of their productivity. What I do instead is to surround the agents with extreme constraints. Unit tests, gherkin tests, QA procedures, quality metrics, mutation testing, test coverage, and a plethora of others. In the end, I have very high confidence in the code they produce because they’ve had to run the gauntlet of all of my constraints and tests.

@jl4guna @posthog Órale y eso que hacían? 😮 yo he estado usando el MCP y todo chido hasta ahorita

It is amazing how the AI is completely changing the game for third-party integrations

I recently used the @posthog AI assistant to push an implementation directly to my repo and then let my agents handle the test & validation

So excited for the future of AI-first development!

Choose optimism

Around the age of twenty-two I realized that my worldview had been deeply imbued with pessimism and cynicism. It was the culture I grew up in. A hostility to new ideas, to anything that strays from the norm. An assumption that if things can go wrong, they will go wrong — that malice is pervasive.

One day, I decided to become an optimist and life became much more fun.

The life of a pessimist is easy but dreary. The life of an optimist is hard but exciting. Pessimism is easy because it costs nothing. Optimism is hard because it must be constantly reaffirmed. In the face of a hostile, cynical world, it takes effort to show that positivity has merit.

To be an optimist, adopt these assumptions:

1. The future can be great
2. People’s intentions are mostly good
3. Ideas are fragile and need nurturing

Every new idea is an unrealized dream. Dreams are delicate and easy to destroy. When an idea presents itself, try to imagine the best version of it — what would make this idea great?

Pessimism and optimism share a trait: both are self-fulfilling. Your intention influences the outcome. Call it karma or, simply, effort. I would rather inhabit a future that has the possibility of being great.

Only optimists can create a great future. Only optimists can imagine it. Only optimists will put in the effort to make it. If you want to create a great future, believe it can happen. Choose optimism.

Was sadly laid off from @utopialabs_ along with many teammates ⛩️

If you know of teams in the 🇺🇸 or 🇨🇦 needing a remote full-stack dev (specializing in mobile & web) with 20+ years of experience, please connect! 👨‍💻

Prefer IC roles but can step into leadership if needed. Passionate about #fintech, #HealthTech, and ecomm, but open to exciting challenges.

RTs and shares greatly appreciated 🙏

Elon acaba de anunciar que los managers en Twitter también deben escribir código, que no puedes ser capitán de caballería si no sabes cavalgar.

Si bien es cierto que los managers de ingenieros/programadores deben ser técnicos, Elon tiene la mentalidad de un ingeniero muy junior

Por ahí vi un tweet que el # de despidos de 2022, ya superó al número de despidos del dotcom bubble...

Es aquí donde los sensacionalistas y las estadísticas mienten. El contexto importa.

Para empezar, hay más gente trabajando en la industria hoy en día, de las que había antes

Being a great manager is easy.

All you have to do is be vulnerable but unflappable, care about people but put the business first, balance competing interests of your team and your boss, obsess over numbers but be a great storyteller, empower your team but give clear direction…

Hace poco tuve mi conversación de desempeño con mi supervisor, y los resultados fueron los siguientes:
- ✅ habilidad técnica
- ✅ habilidades blandas
- ✅ colaboración con equipos no técnicos
- ⚠️ Eliminación de riesgo en los proyectos
- ⚠️ Habilidad para delegar
