mamori isn't just secrets — it watches feature flags too: LaunchDarkly, Unleash, Flagsmith, ConfigCat, Split, GrowthBook, Flipt, GO Feature Flag. Typed flags in your Go config struct, reconciled at runtime, validated before every swap. #golang
Every mamori provider is just a Provider, so decorators nest freely: Cache to cut API cost, Failover to a replica, RateLimit twitchy backends, Audit every access (never the payload). One interface, so it all composes. #golang
Secrets leaking into your Go logs? mamori's secret.String renders as [REDACTED] in fmt, JSON, and slog. Only Reveal() exposes the value — greppable in code review. A shipped go vet analyzer flags sensitive refs stored in plain strings. #golang
What does your config do at runtime? mamori + OpenTelemetry: resolve-duration histograms, refresh & error counters, a span per resolve. The bridge implements tiny Meter/Tracer interfaces — the core stays OTel-free, or write your own sink (Prometheus, statsd). #golang
Honoured to be renewed as a Microsoft MVP for a third year for Microsoft Foundry! Excited to keep learning and building Thank you! 💙 #MicrosoftMVP #MicrosoftFoundry
2/ My favorite part: the CLI ships its own MCP server. diamond mcp exposes 18 live MLB data tools over the Model Context Protocol, so you can drop them into ANY agent platform (Claude, Cursor, your own). Your terminal app becomes an AI tool provider.
Meet Diamond ⚾, a top-tier MLB stats platform I built. The MLB app ate up space and the stats were... meh. So I built my own: live scores, standings, leaders & deep player profiles. On the web AND in your terminal. 🌐 diamond.xavidop.me 🧵 A bit on how it's built 👇
Another year, another Google I/O! It was so great to see fellow GDG Organizers, GDES and Mentors!!
I’m super happy to share that I’ve officially been approved for my 3rd Google Developer Experts category! This one is especially unique for me: Go. Over the past years, I’ve been contributing more and more to the Go ecosystem, especially around AI, Genkit, cloud-native development.
I just released genkitx-temporal! A new Genkit plugin to run Genkit flows as Temporal Workflows, bringing durable execution, retries, timeouts, cancellation, scaling, and Temporal UI visibility to your GenAI apps. buff.ly/5itGbp5
I may not have the 100K YouTube subscriber plaque, but We do have the 100 billion OpenAI tokens one! 😂
All set for Google Cloud Next here in Las Vegas! 🚀 Excited for a few days of learning, building, and connecting with amazing people in the ecosystem. Who else is coming? 👀 Ping me in DMs, would love to meet up!
Grateful to everyone who came to my talk yesterday on Genkit at the European GenAI Summit! 🙌 It was amazing to see so much interest, curiosity, and great conversations around building the future of AI. Thanks for the energy, the questions, and for making it such a fun session!
Big update for the Genkit Java ecosystem 🔥 We’ve launched a brand new website for Genkit Java: 👉 buff.ly/SiEay79 And we’re introducing Claude Code Skills to help developers build faster and smarter with Genkit Java: 👉 buff.ly/jXwnJe5 Give it a try and let us know what you think 💡
Who said Genkit only works on Google Cloud? 👀 New post: Running Genkit on AWS Lambda with the Bedrock plugin. Typed flows. Streaming support. Zero-boilerplate Lambda handlers. One-line model swaps between Amazon Nova, Claude, and more. 📖 buff.ly/qSp6UFq
As a mentor with the @GoogleDeepMind Accelerator, I’ve seen firsthand the impact this program has on early-stage startups. The Robotics Cohort is now open for applications! If you're a Europe-based robotics startup working on advanced AI-driven systems: buff.ly/UVr5MO7
We’re incredibly honored to be named a 2026 G2 Best Software Award winner for Best Agentic AI Software Products 🏆 Out of 1,392 products, Voiceflow was recognized as a leader in the brand-new Agentic AI category by G2. Read the full announcement here: buff.ly/qmt1qhz
🚀 La agenda del GDG Madrid no para de crecer 🔥 ¡Cada semana sumamos más eventos, talleres y charlas que te ayudarán a seguir aprendiendo, conectando con la comunidad y creciendo profesionalmente! 👉 Revisa todo lo que tenemos preparado en nuestra comunidad: 💡 buff.ly/ja0Mth8
🚀 New in the Genkit × AWS JS plugin: you can now deploy your Genkit Flows directly as AWS Lambda handlers with a simple helper 👇 This makes building serverless GenAI backends ridiculously easy. Introducing AWS Lambda support, turn your Flow into a Lambda function in one line.
We’ve been building the future of conversational AI for years, from chatbots to truly intelligent AI agents. We aren’t just another agent startup; we’ve been here since the early days, learning, iterating, and shaping what comes next. 📅 February 18th 🚀 buff.ly/dy2b9Hs
Still can’t quite believe this, but it’s official I’ve been renewed as a @GitHub.com Star for 2026 Out of 180+ million developers on GitHub, only ~80 people worldwide are part of this program. Being renewed means a lot; it’s a reminder that the work we do in open source, education actually matters
Grateful and excited to share that my Google Developer Expert (GDE) membership has been renewed for 2026. It's been 4 years! Huge thanks to the GDE team for the trust, and to the community for constantly pushing me to learn, share, and build better things together.
Proud moment to share, Voiceflow is now HIPAA compliant. This milestone builds on a long-term commitment to security and trust. We achieved ISO 27001:2022 back in 2021, followed by SOC 2 in 2024, and now in 2026, we’ve reached HIPAA compliance. You can find more information here: buff.ly/GcHllR5
