🟢 Li & Wang (2023), usando datos de compañías chinas cotizadas, confirman que la innovación tecnológica en IA aumenta la TFP, principalmente a través de reducción de costes, mayor uso de mano de obra cualificada, digitalización y eficiencia en I+D open.substack.com/pub/ainative... #ai #ainative

Review them weekly and bring them to 1:1s. Metrics make conversations about promotion factual, not fuzzy. 🧭 Signal: You can show progress with hard data, and your manager uses your metrics as input for performance reviews.
1) Measure your impact 👉🏼 Make it objective. Pick 3–4 metrics that reflect your scope. Some suggestions: 🟢 Cycle time. 🟢 Number of incidents. 🟢 Percentage of planned technical work delivered.
🟢 Legal / Finanzas / RR. HH.: asistentes de IA que revisan contratos, analizan presupuestos y automatizan respuestas a FAQs internas. open.substack.com/pub/ainative... #ai #ainative #nativeai #cloudnative
🟢 Producto: uso de Figma AI + Jira AI + Confluence AI para elaborar requisitos claros y exportarlos automáticamente a tickets.
🟢 Ventas: prompts compartidos para escribir emails, calificar leads y hacer demos más eficaces.
Se trata de convertir cada departamento en consumidor y prosumidor (bonito palabro) de IA. Algunos ejemplos que veo venir son:
🟢 Legal / Finance / HR: AI assistants that review contracts, analyze budgets, and automate responses to internal FAQs open.substack.com/pub/ainative... #ai #ainative #nativeai #cloudnative
🟢 Product: using Figma AI + Jira AI + Confluence AI to craft clear requirements and export them directly to tickets.
🟢 Sales: shared prompts to write emails, qualify leads, and deliver more effective demos.
It’s about turning every department into a consumer and prosumer (yes, that’s a word!) of AI. Some examples I foresee:
If you’re a Senior Software Engineer or an early Tech Lead aiming for Staff Engineer/leadership, stop treating growth as a mystery. Combine day-to-day craft with deliberate influence: 🟢 Measure what matters 🟢 Lead by example 🟢 Make others better newsletter.optimistengineer.com/p/the-concre...
5 minutes, no more 😉
I'm not going to teach you how to create AI agents, but I will show you how to use them in your engineering organization to deliver value to your customers through your SaaS product 👇🏼 open.substack.com/pub/ainative... #ai #ai #ainative
No te voy a enseñar cómo crear agentes de IA, pero si te voy a enseñar cómo usarlos en tu organización de ingeniería para dar valor a tus clientes a través de tu producto SaaS 👇🏼 open.substack.com/pub/ainative... #ia #ia #ainative

The effect remains after controlling for endogeneity and robustness checks, driven by added value, skilled labor, and tech modernization.
🟢 Zhang et al. (2023) analyzed data from 1,200+ manufacturing firms in China and showed that every 1% increase in AI adoption led to a 14.2% increase in Total Factor Productivity (TFP).
Is that a Terminator? 😅
Lead with empathy. Code with clarity.
Y creo que, en esencia, sería lo mismo: quieres "trepar" en la escalera social para tener relevancia
Por lo que he experimentado en Linkedin, es una de las mejores formas de conseguir visibilidad en esa red social. Veo cada vez más gente con una estrategia para crecer en las redes sociales (por distintos motivos) y los hay a los que se les da muy bien
👉🏼 Se trata de cambiar la forma en que trabajamos a nivel organizacional y poner al ser humano en el centro del proceso. open.substack.com/pub/ainative...

Thanks Dane! I took a look into it, but I'm not sure what features it supports beyond displaying posts from the stream. Would you know if it supports CRUD operations over BlueSky?
Is there any Java SDK for Blueksy? #bluesky #SDK #java #atproto
Yo yo me la juego también, diciendo que esto lo tendremos también www.imdb.com/es-es/title/...
Is anybody else tired of the IDE (vscode, Intellij), vitaminized with an AI Agent, never stops making you inline suggestions to your code? Damn! I have to click here and there with the mouse to get rid of those semi-transparent layers with suggestions that prevent me from seeing my code! #AI
De verdad, esto de llamar productividad a estar 14+ currando no solo es malisimo para la salud física y mental, lo es para la familia, para las amistades, para la vida en general. Eh, que yo he estado ahí, no hablo de oídas. Estoy contándolo de milagro. Cero bromas con eso
For those like me we are since a while in the web development… Do you remember this?

3️⃣ Usemos la IA para lo que NO es nuestro trabajo. ¿Te gusta programar?, entonces, ¿por qué dejas que la IA haga el trabajo que te gusta en lugar de delegar en la IA las cosas que te gustan?
2️⃣ Flujo de Trabajo con TDD y Agentes de IA. No dejes que la IA te haga el lío y aprende a usarla para lo realmente importante.
1️⃣¿Qué significa ser AI Native? En esta primera edición, sentaré las bases para tener más claro hacia dónde vamos.
En septiembre arrancamos con mi nueva newsletter 🧭 Brújula AI Native y ya os puedo contar las cositas que te puedes llevar 🧵👇🏻
newsletter.optimistengineer.com/p/you-are-th...
I've written a full guide with code examples and the 4 core principles for writing AI-ready Python tests. It's the playbook for harnessing AI speed without sacrificing quality. Read it here: www.sebastiansigl.com/blog/type-sa... #Python #Testing #AI #SoftwareQuality
The solution starts with a mindset shift: 𝗧𝗲𝘀𝘁 𝗖𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀, 𝗡𝗼𝘁 𝗜𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻. Your tests should verify the "what," not the "how." This makes them resilient to the constant refactoring that AI-assisted development encourages.

Here is my latest article where I share insights about the onboarding process: medium.com/the-tech-col... #softwareEngineering #management #onboarding
El movimiento a AI Native es una realidad para muchas empresas y reto a la vez, porque nadie lo ha hecho aún. El banco Santander va a ello cincodias.elpais.com/companias/20...
Tell the @bsky.app team to implement two-factor authentication (2FA) for 3rd party PDSs
But, is it an "advice" to not upgrade? Or technically it is not possible?

🟢 Y también para quienes estén trabajando a nivel de procesos en una empresa con un producto SaaS, ya que hablaré cómo cambiar los procesos que anteriormente nos llevaron a ser Cloud Native.
Para quién está destinado: 🟢 Pues para personas que desarrollan software sin duda, ya que hablaré de patrones, técnicas, y arquitecturas para utilizar la IA en tu plataforma SaaS.
¿Por qué? Porque justo estoy embarcado en esa transición y mi intención es enseñarte todos los errores y éxitos.
Por fin, me lancé a escribir una newsletter en Substack en español. Y en ella voy a contar cómo hacer la transacción de un modelo Cloud Native a un modelo AI Native.
In today’s issue, I get you back to technical leadership by understanding the managed service AWS SQS. newsletter.optimistengineer.com/p/design-pat...
Tomorrow, I will share with more than ✨1.4K subscribers✨ a new email about Design Patterns With AWS SQS. Subscribe now and receive it tomorrow morning in your inbox 📥 👇🏼 newsletter.optimistengineer.com
Developers, we have to use AI in a Pair Programming mode, instead of agent generator mode. It's an important shift that will help you to get more profit from that technology. Pro tip: AI never gets tired, so use Pomodoro technique
The more I see it, the more I'm sure it's the way: 👉🏼 Leadership is about caring people.
Otra nueva semana de regalos de ciberformación y vamos con la P-74 "Atalaya", que me afecta en lo personal como víctima continuada de (ciber)acoso. Me gusta pensar que mi experiencia servirá para librar a otros de esta lacra. Como siempre, presentación disponible en: github.com/jose-r-lopez...
Indeed, there is a whole world over there about API models and pricing. In my report, I just tackle a few I consider for a project I'm working on. Thanks for sharing Tero! I will link your post in my report!
There are plenty of other API models on OpenAI. Did you use this one: platform.openai.com/docs/pricing? For example, the 4.1-nano costs next to nothing for simple summarising tasks with low quality requirements
Read it here 👇🏼 newsletter.optimistengineer.com/p/ai-for-soc... #softwareengineering #leadership #aicostsavings
In today’s issue, I analyze for you the major AI API options, see exactly how much a “medium-length post” costs, and decide which model fits your use case. By the end, you’ll know where to invest your tokens… and your energy.

If you’ve ever felt stuck after spinning up your Cloud Native stack, wondering how to weave AI models into your microservices, transform your stack to become AI Native, or architect for continuous learning, this is for you.
I’m thrilled to share that the AI Native Compass newsletter officially launches this September. 📆
New project folks! At work, I've started the journey of moving a company from an Start Up with an on-premise product to become Cloud Native. This year, I started the next transformation to an AI Native company. And because the best way for me to learn is explaining it on the fly… 🥁🥁🥁
Balance speed with checks: integrate AI suggestions into your CI pipeline so you catch regressions early. Keep your velocity without sacrificing stability. newsletter.optimistengineer.com/p/why-clean-... #softwareengineering #leadership #cleancode
You ship quickly today but spend twice the time fixing and refactoring tomorrow. That backlog grows fast.
⚡️ AI can shave off hours writing boilerplate, but is your delivery really faster? Low‑quality code takes 2.24× longer to maintain.
I would like to say it was an "Easter egg"... But I would lie 😅
There's a typo in that picture. "Optimize software delivery" is twice, and missing "Mentoring of teammates"
If you're in the Tech Lead role, this is the best advice I can give you 👇🏼 newsletter.optimistengineer.com/p/measuring-... #techlead #leadership #softwareengineering
It's just money! What about your feelings!? That's the important part! 😅 #kidding
El día 14 habrá un evento de ciberseguridad en la Universidad de Oviedo para presentar nuestro programa de microcredenciales universitarias en estos temas, donde vendrá gente muy importante y yo 🫠 www.uniovi.es/en/-/actos-d...
Did you know that?👇🏼 Fixing a bug or shipping a small feature takes 124 % more time in low-quality code compared to healthy code. newsletter.optimistengineer.com/p/why-clean-...
"I'm going on PTO, thanks"
Being capable to evaluate the impact of AI in our engineering organization is something crucial. Still today, I did not find a proper way to do so
Action tip: Always run an automated quality scan (SonarQube, CodeScene) on AI‑authored code. Catch issues before they slow you down! newsletter.optimistengineer.com/p/why-clean-... #softwareengineering #leadership #cleancode
Studies show low‑quality code has 15× more bugs. If you blindly accept AI suggestions, you could be building future headaches.
🚀 Just started using an AI coding assistant? Amazing! But beware: even AI-generated code can carry hidden “debt.”
