In this episode of the Elixir Mentor Podcast, I chat with Enrique Leigh, founder of Prende Café in Chile. We explore how he built a specialty coffee subscription business using Phoenix LiveView, his journey from marketing and ad tech to becoming an Elixir developer, and why he chose custom e-commerce over platforms like Shopify.Enrique shares the WordPress crash during a Chile vs Brazil match that sparked his interest in Elixir, and how building his own coffee business became the perfect way to finally learn the language. We discuss UX principles from "Don't Make Me Think," marketing frameworks like Jobs to Be Done, and the counterintuitive lesson that adding more checkout steps can actually increase conversions. He also explains the specialty coffee value chain, from sourcing beans in Brazil to roasting and running a physical café alongside the e-commerce platform.Our conversation covers practical entrepreneurship topics including MVP philosophy, building subscription and coupon systems with Mercado Pago, using Oban for job scheduling, and content marketing strategies that work. Enrique shares insights on balancing Iron Man training with running a family business, productivity techniques from the Flow Research Collective, and the evolving landscape of ad tech after GDPR. We also discuss his future goals of learning Nerves to build IoT coffee machines and the growing Elixir community in Chile.The episode wraps up with advice for aspiring entrepreneurs: just launch it. Enrique emphasizes that the cost of inaction is often greater than the cost of action, and with tools like LLMs that work remarkably well with Elixir, there's never been a better time to build your own products.Resources Mentioned:- Don't Make Me Think: https://sensible.com/dont-make-me-think/- Oban: https://getoban.pro/- Jido: https://agentjido.xyz/discordConnect with Enrique:- Website: https://www.prendecafe.cl- X/Twitter: https://x.com/EnriqueLeigh- LinkedIn: https://www.linkedin.com/in/enriqueleigh/Sponsors:- Paraxial.io: https://paraxial.io- Jido: https://agentjido.xyz/discordSUPPORT ELIXIR MENTOR- Elixir Mentor: https://elixirmentor.com

Mikh Ahmed joins me to talk about SWARMMO, a massively multiplayer online browser game he's building entirely with Elixir and Godot. After experiencing burnout from AWS Lambda and serverless tooling at a Canadian fintech startup, Mikh discovered Elixir and realized it was exactly what he'd been looking for to build his dream game project.We explore how the BEAM's actor model maps perfectly to game architecture, with individual player processes, hierarchical AI units that form squads and platoons, and a simulation where NPCs actively compete for territory. Mikh shares his experience going from zero Elixir knowledge to building a game server that can handle a thousand concurrent AI units while using only 4GB of RAM and 50% CPU.The conversation covers the realities of indie game development: failed crowdfunding campaigns that led to private support, the challenge of marketing when you'd rather be coding, and plans for a Steam release and version 1.0 launch. We also discuss the potential for LLM-powered NPC personalities, why minimal dependencies matter, and how game design psychology from board games applies to digital experiences.Connect with Mikh:- X: https://x.com/SWARMMOOFFICIAL- SWARMMO: https://swarmmo.games/?lang=enSUPPORT ELIXIR MENTOR- Elixir Mentor: https://elixirmentor.com/?utm_source=elixir-mentor

Join Brazilian software engineer George Guimarães, the mind behind Soothsayer, as he dives into the world of time-series forecasting using Elixir. He discusses how Soothsayer tackles seasonal trends and holiday impacts with neural networks. George shares why Elixir's ecosystem excels in AI development, highlighting the benefits of its concurrency model. He even introduces the concept of Agent Engine Optimization (AEO) as the next big thing for enhancing user experience. Expect insightful takes on AI, agentic commerce, and the Elixir community!

In this episode of the Elixir Mentor Podcast, I chat with Isaak Tsalicoglou, author of Elixir Software Engineering. Isaak shares hard-won lessons from building production Elixir API clients, covering validation strategies, error handling approaches, authentication flows, and architectural patterns that actually work in the real world.We explore Isaak's journey back into programming through building internal tools for his family's industrial equipment business, and how that led to writing a comprehensive guide on REST API client development. He explains his approach to request validation, why he ultimately decided against using Ecto schemas for API responses, and the importance of resisting unnecessary complexity in software architecture.The conversation covers practical API design topics including how to structure clean RESTful routes, avoiding tight coupling between APIs and UIs, and finding the right balance between over-serving and under-serving data. Isaak also shares his thoughts on LLM-assisted development, explaining why he prefers using AI as a code reviewer rather than fully automated coding, and discusses his self-hosting infrastructure setup for privacy-conscious applications.This episode offers valuable insights for anyone building API clients in Elixir or thinking critically about software architecture decisions and their long-term implications.Resources Mentioned:- Elixir Software Engineering: https://leanpub.com/elixir-software-engineeringConnect with Isaak:- X: https://x.com/realMrLaminar- LinkTree: https://linktr.ee/tisaakxSUPPORT ELIXIR MENTOR- Elixir Mentor: https://elixirmentor.com/?utm_source=elixir-mentor
