PostgreSQL Query Rewriting Techniques The previous articles in this series covered performance problems you fix by adding indexes, restructuring joins, or tuning memory. This one is about the queries where the plan is "fine" — every node is doing something reasonable — but the query itself is asking the wrong question, producing unnecessarily large intermediate results or forcing the planner dow
Building a News Aggregator Without an Engagement Algorithm I have been building a project called WeSearch: https://wesearch.press It is a free news aggregator that pulls from hundreds of sources, keeps discovery mostly chronological, adds source/bias context where available, preserves permanent daily archives, and allows anonymous discussion on stories. The project started from a simple frustrat
A deep, opinionated, practical guide for the human running a software business alone. Hard-won lessons, decision frameworks, and the actual mechanics of going from idea → first dollar → first $10K MRR → first $1M ARR — without a co-founder, without a team for as long as possible, and without burning out. If you read only one section first, read §2 Mindset, §4 Validation, and §6 Distribution-First.
Three weeks ago I shipped IndieOps — a free invoicing and client management tool built specifically for freelancers. Here's the honest version of how it went. It handles the boring-but-critical stuff that eats freelancer time: creating professional invoices, collecting payments via Stripe, sending automatic payment reminders, and keeping a client directory. All free. No "upgrade to send more than
I used to send out application after application and hear nothing back. Not a single reply. At first, I thought my resume wasn't impressive enough. So I made it fancier. Added columns. Played with layouts. Tossed in some icons. Still nothing. Then I learned about Applicant Tracking Systems. Companies use software like Lever, Greenhouse, and Workday to scan resumes before a human ever sees them. If
I built Clever Deploy because every time I wanted to ship a small side project, the deploy story turned into a project of its own. 1. Surprise bills. I'd push a side project to a "free tier" 2. Complexity. I've setup Jenkins in Kubernetes for clients - believe me, you don't want that kind of complexity. What I wanted was simplicity and no unexpected bills. A deploy platform with two rules: Click D
SQL is widely known for data querying and manipulation but systems do grow; data becomes larger; processes become repetitive and operations become sensitive. SQL has some features which enables it to be considered a fully fledged programming language. Some of the features which I discuss in this article are procedures, functions and transactions. Each of these concepts serve distinct purposes. Sto
When setting up infrastructure for a startup, cost control is not something to “add later.” It has to be built into the foundation from the very beginning. AWS operates on a pay-as-you-go model. That flexibility is powerful, but it also means that a small misconfiguration, an unused resource, or an unexpected traffic spike can quickly turn into a serious bill. On Day 1, we focused on security (roo
