💡 Did you know that most startups fail not because of bad ideas, but because of weak tech execution? In the past few years, I’ve helped founders in HealthTech, Real Estate Tech, and EdTech turn their early concepts into stable, scalable products that users love. Here’s what I’ve learned: 1️⃣ Simplicity beats complexity, especially in MVPs. 2️⃣ UX matters as much as backend logic. 3️⃣ Clear communication between devs and non-tech founders is game-changing. Curious to know, what’s the biggest challenge you’ve faced while turning an idea into a working product? #StartupTips #ProductDevelopment #FullStackDev #HealthTech #RealEstateTech #EdTech

Cover image for Build Your Own Notion-Style App with Claude Code in One Hour

I love Notion. I just don’t love paying $29/month. That adds up to $348/year. With Claude Code, it’s now realistic to build a personal Notion-style app in a single hour — and build it exactly how you prefer. So I started building Numun Notes for myself: a native app that runs directly on my Mac: ✅ pages + editor ✅ wiki links + backlinks ✅ databases with views (table + kanban) ✅ filters/sorts/grouping + templates ✅ offline-first + fast search Next: I’m merging Notion + ClickUp into one master app, so Numun Notes becomes exactly what I want for productivity.

Numun Labs is a physics and technology laboratory focused on translating first-principles research into measurable, testable, and deployable systems. The lab develops foundational models, research software, and experimental frameworks that turn abstract physical laws into operational tools. Work spans mathematical modeling, simulation engines, verification-grade analytics, and software systems designed to validate theory against real-world data. Numun Labs operates at the boundary between discovery and implementation—building systems that don’t just hypothesize, but measure, predict, and close loops between theory and reality. Projects emphasize rigor, falsifiability, and reproducibility, with an engineering mindset toward long-term applicability.

Numun.io (http://Numun.io) is an autonomous agent and workflow execution platform designed to turn intent into action—reliably, securely, and at scale. Numun enables users and teams to design, deploy, and run AI-powered agents and workflows that browse the web, call tools, orchestrate systems, and complete real tasks end to end. At its core is a contract-based execution model that emphasizes determinism, observability, and accountability—bringing production-grade discipline to AI agents. Numun is built for developers, operators, and founders who need agents that actually work in the real world—not demos that break under pressure. This project includes full-stack platform development, execution infrastructure, agent runtime design, workflow orchestration, and system-level reliability engineering.
