One Year With ThinkPad and Linux (From Macbook Pro)

A few thoughts about my experiences switching from Mac to a ThinkPad with Linux the past year. For context, I'm the founder and maker of Wobaka.com and Bootstrap.email. I work with front/backend development, design, marketing and sales every day. I code primarily in Clojure + ClojureScript but I

Navigation Wars: Top or Side?

I've made quite a few apps the past years. A social network for travel, local activities directory (kind of like Foursquare but for activivites), a word game, a screenshot and bookmarking tool, a design curation, data driven color palettes, a CRM for small businesses. Well. I think you get it.

Optimizing large table rendering in React

I recently had an issue working on Wobaka.com where the contacts table were taking too long time to re-render. What happened was that when more than 100 contacts were rendered, the UI felt laggy and sometimes froze when changing filters (free text, lead status, etc). I wasn't happy with

Continuous Integration and Delivery for Monorepos

Sentry with User Context for Express

Today I tried to add some user context to Klart.io's issue tracking. This is helpful since it allows you to track which users get what errors. Klart's backend is based on Node and Express so naturally this will target those technologies. My first atempt was to use the default

Testing Express Apps with Mocha, Chai and Puppeteer

I've been working a lot on improving the test coverage for Klart.io recently. When the app was small I only had a few integration tests doing some API requests and asserting the response. The rest was tested manually in the browser. Now it's growing bigger both feature and user

Context In Design

One of the best things about making something for yourself is that when you use something every day you will notice issues and make minor improvements all the time. Sometime you find these issues yourself and sometimes users mention them and you realize that, "Oh, yeah, this is a
