5 Essential Security Moves Every Startup & SMB Must Make to Prevent Cyber Attacks

If you’re working at a startup or SMB, you might think “we’re too small to be targeted.” You might believe that cyber attackers only go after Fortune 500 companies with deep pockets and valuable data worth millions.

That assumption could destroy your business.

Here’s the uncomfortable truth: attackers don’t discriminate by company size.
They discriminate by vulnerability.
And right now, small and medium-sized businesses represent the softest, most lucrative targets in the entire threat landscape.

Here are the top 5 things you should do.
Right now.

Building Resilient Microservices for Bootstrapped Apps 🏃🏼‍♀️🚵🏼

Out on the trail, your phone isn’t plugged into a wall. Every network ping drains battery. Every background process steals CPU cycles that could keep your GPS running for another hour.

In my previous post on the GPX Water Mapper, we explored visualizing water sources along your route. Now we’re going under the hood: designing a microservices architecture that respects the constraints of outdoor apps—where a dead battery isn’t just inconvenient, it’s potentially dangerous.

Imagine getting a real-time hydration alert as you approach mile 12 of your desert bike ride, calculated from your current pace, the temperature, and known water sources ahead.
All while using less battery than a typical podcast app.

What we’ll build:

  • A microservices approach that actually makes sense for small teams
    (spoiler: not everything needs to be a service – moreover, in many cases you should avoid it and run on a monolith)
  • Event-driven patterns that keep your app responsive without constant polling
  • Node.js implementations you can deploy on minimal infrastructure
  • Real-world trade-offs: when to split services and when a monolith wins

10 Startup Lessons from David Deutsch’s The Beginning of Infinity

David Deutsch’s The Beginning of Infinity isn’t a business book. It’s a bold meditation on science, philosophy, and human progress. But buried in its pages are principles that can reshape how startup leaders think about building companies, products, and cultures.

Startups are problem-solving machines.
Problems never stop coming; solutions never stop creating new challenges. That cycle is the essence of growth. Deutsch gives us a framework for seeing this not as a burden, but as the path to infinity.

Here are ten core lessons from the book, translated into practical guidance for startup leadership, with examples of how a CTO might put them into action.

Scaling Engineering Teams: Lessons from Google, Facebook, and Netflix

After spending over a decade in engineering leadership roles at some of the world’s most chaotic innovation factories—Google, Facebook, and Netflix—I’ve learned one universal truth: scaling engineering teams is like raising teenagers. They grow fast, develop personalities of their own, and if you don’t set boundaries, suddenly they’re setting the house on fire at 3am.

The difference between teams that thrive at scale and those that collapse into Slack-thread anarchy typically comes down to three key factors:

  • Structured goal-setting
  • A ruthless focus on code quality
  • Intentional culture building

Let me share some lessons I learned from scaling teams at Google, Facebook, and Netflix. Here are a few frameworks, metrics, and tools that actually work when you’re trying to scale from 10 to 100 to 1,000+ engineers—without losing your mind or your best people.

Essential System Design Tips for Startups

You’re launching your first startup… Well, Congrats!

Whether it’s a SaaS invoicing tool, an e-commerce shop for handmade goods, or a new social app, you’ll quickly hit a truth: system design is your blueprint.

Done right, it makes your app boringly reliable. Done wrong, you’ll spend more time firefighting than building features.

This post is based on Sean Goedecke’s excellent piece on system design, reshaped with a founder’s lens: lean, practical, and ready for bootstrapped growth.

Weather 4 Bike: From Forecasts to Ride Decisions

Why

Most weather apps just tell you the numbers—temperature, wind, UV, etc.—but as cyclists, we need to know what those numbers mean for the ride.

Weather 4 Bike bridges that gap: it translates raw weather forecasts into clear, activity-aware guidance for road, gravel, and MTB. With one glance, you know whether to head out, wait, or change routes.

The Future of Coding: LLMs as Collaborators

The rise of large language models (LLMs) has been one of the most transformative developments in software engineering in decades. Tools like GPT4.1, Gemini 2.5 Pro, Claude Opus 4, and various AI-powered code editors such as Cursor (or CoPilot) promise to change the way we build software.

But as these tools evolve and mature, the real question isn’t if we should use LLMs—it’s how.

There’s an emerging split in philosophy between two approaches: full automation through AI agents and IDE integrations, or human-led development using LLMs as intelligent partners.

Based on real-world experiences and a critical review of LLM-based coding tools, the most effective path today is clear:

LLMs are best used as powerful amplifiers of developer productivity—not as autonomous builders.

Let’s break down why.

How to Use ngrok and LocalTunnel: Expose Your Local APIs to the World

Intro

As developers, we often face the challenge of testing our local applications with external services, webhooks, or mobile devices. Whether you’re developing APIs that need to communicate with AWS/GCP/Azure services, testing webhook integrations, or simply want to demo your work from different devices, exposing your localhost to the internet becomes essential.

This guide will walk you through two popular solutions: ngrok and LocalTunnel, showing you how to securely expose your local development server to the world.

What Are Tunneling Services?

Tunneling services create a secure tunnel from a public endpoint to your local machine, allowing external services to reach your development server without complex network configuration or deployment.

Common Use Cases

  • Testing webhooks from third-party services (Stripe, GitHub, etc.) — You can connect your local code directly and debug it more efficiently.
  • Sharing your work-in-progress with clients or team members — Instead of pushing it to some remote server. Useful in all the cases, where you are still ‘not ready’.
  • Testing mobile applications that need to connect to your local API — A must have in almost all cases.
  • Integrating with AWS services that require publicly accessible endpoints
  • Cross-device testing and debugging
