Essays, playbooks and field notes from our CTOs, architects and leads. Written for people shipping real product.
Most architecture methods try to predict which failures will hit. Residuality Theory does the opposite: it throws random stressors at a design and keeps whatever survives. The randomness is the point, because resilience that depends on predicting the future is not resilience at all.
Discover how branded types can improve your TypeScript code quality, make your intent clearer, and catch bugs before they even compile.
Building desktop apps with NativePHP misuses Laravel’s core strengths, creating potential security risks and practical limitations.
Involving engineers in product specification meetings reduces costly iterations and accelerates feature launches for SaaS startups.
Many SaaS startups over-engineer their architecture with microservices. Here's why that's usually a costly mistake—and what to do instead.
Should startups test everything before shipping? We break down how to balance testing with product velocity—and why 100% coverage is often the wrong goal.
AI tools are transforming how we code, but they're not replacing the experience needed to build real software. Let’s talk about what vibe coding gets right—and what it gets very wrong.
Everyone breaks production eventually. This guide walks through how to take responsibility, communicate with your team, and make real improvements after something goes wrong. A must-watch for engineering managers and developers.
Does every startup need an interim CTO? Fractional CTOs can accelerate growth and solve complex challenges—when brought in at the right time. Learn when it’s too early, too risky, or simply not the right fit for your business.
AI tools are reshaping how junior engineers approach problems, often replacing simple solutions with overly complex ones. Here’s why foundational thinking still matters. A real-life case of AI over-engineering gone wrong highlights why understanding problem domains still beats prompting.
Single points of failure (SPOF) in startups lead to lost revenue, delays, and investor concerns. Building a documentation culture early reduces risk and ensures scalability.
Some tasks are a slow grind, like simmering a big meal that takes hours to come together. Others are quick and satisfying—tiny fixes that deliver an instant hit of progress, like a little dopamine boost to keep you going.
A great product roadmap balances business goals with technical sustainability. Ignoring engineering input leads to technical debt and bottlenecks that slow growth. In this video, we discuss how SaaS teams can integrate engineering priorities into the roadmap for long-term success.
Selling bespoke features to customers might seem profitable, but it changes your SaaS business model. Instead of a scalable product, you become a service provider, stuck maintaining one-off features. Learn why this approach is risky and how to build for long-term success.
Selecting the right tech stack is critical for AI startups. Python is essential for data science, but the backend, frontend, and infrastructure choices determine scalability and efficiency. Explore the best tech stack combinations, hosting tools, and ETL solutions to future-proof your AI startup.
Forced API migrations without a rollback plan? That’s how businesses lose trust—and money.
