It’s easy to optimise for the thing directly in front of us. A feature needs to ship. A bug needs fixing. A deadline is approaching. So we make the decision that gets us there fastest. Sometimes that’s exactly the right decision. But technical strategy is about asking one more question: “What does this decision mean for us six months from now?” A technical decision usually has at least two dimensions: Immediate value — Can we solve the problem now? Long-term impact ...

You've written it a hundred times. In your CLAUDE.md , in your system prompt, in ALL CAPS: NEVER put "use client" at the page level. NEVER commit @ts-ignore without a reason. And your agent does it anyway. Not always — that would almost be easier to deal with. It follows the rule for the first 50k tokens, then quietly stops. Or Sonnet follows it and Haiku doesn't. Or it follows nine rules and forgets the tenth. Here's the thing I finally accepted: a rule in a prompt is a req...

I spend more hours in a terminal than in any other window, and for years the configuration behind it lived nowhere: a .zshrc I had edited so many times I no longer knew which line did what, a colour scheme picked in a preferences dialog, an SSH config that only existed on one laptop. What follows is what that turned into. Not a list of everything installed on my Mac, but the terminal I actually type in and the two-part trick that keeps it reproducible: every setting is a plain-text file, an...

Sorting a slice by one field is easy. Filtering one collection is easy. Returning (T, bool) is idiomatic. So is writing a nested loop. The friction appears when the same ordering must be shared by a stable sort and an extrema operation, a filter must be reused across several APIs, or a nested traversal grows into four nearly identical loops. At that point, the code is still simple locally, but the semantics are scattered across call sites. Shuttle is an attempt to give those semantics ...

Nowadays most social and pen‑pal apps are built around speed. Swipe left, swipe right, quick short messages, endless notifications. Platforms reward fast replies and surface‑level first impressions. We can chat with dozens of people every day, yet many of us still feel lonely. Connections are easy to start, but rarely grow deep. Even some existing pen‑pal apps gradually move toward swipe‑driven matching, focusing heavily on profile pictures instead of real thoughts. I wanted something diff...

Have you ever stopped to think about the risk of having a pipeline where any merge into the main branch deploys straight to production without a single safety gate? For a long time, our workflow here was that classic setup almost every developer has used at some point: merge on main triggering an SSH script with git pull and pm2 restart It worked for day-to-day tasks, but it gave a false sense of stability lol The reality check hit when I found a critical blind spot in the automation: r...

React Form Backends Compared: Serverless Functions vs. Form-as-a-Service React makes building a form straightforward. What happens after onSubmit is a different question: you still need somewhere to validate, process, store, or forward the submission. Two common approaches are writing a serverless function yourself or using a hosted form backend such as onsubmit.dev (form backend). This article compares the two, using Vercel/Netlify-style functions for the DIY approach and onsubmit.dev w...

For a long time, whenever we hear 'User Experience', we instinctively think of UI/UX designers, product designers, or maybe frontend engineers. Why? Because we tend to think users interact first with a graphical or command-line interface, while the backend engine plays little to no role in how they experience the product. The first half is correct. The second half, incorrect. A user doesn't experience your frontend in isolation. They experience the entire system. As I continue to...

What I Built HalfAdder, FullAdder, Add16, Inc16, And ALU. How I Solved Like when I built logic gates, I started with analyzing truth table of HalfAdder , FullAdder . HalfAdder was really easy. After looking at the truth table, I could map the sum and carry outputs to logic gates pretty quickly. FullAdder was also not hard since it's really similar to HalfAdder except that it can add 3 bits. I realized that I could build it by combining some chips and logic g...

I shop on a laptop. A lamp on Amazon that costs too much. A jacket in a listing photo. Something I saw on eBay and wanted to check on Temu. On my phone, that is a camera tap. On desktop, the camera icon is mostly missing. So I built SameSame , a browser extension I still use every day. It does not send your photo to a third-party reverse-image API. It opens the visual search each store already runs - the same one their mobile apps and some out-of-stock flows use - from the page you are alrea...

I started my career as a software developer, Initially a front end developer and then became a full stack developer where success often meant solving difficult technical problems, building reliable systems, and delivering good software. Becoming a co-founder changed that perspective. Suddenly, building a product wasn't just about writing code. It was about understanding the problem deeply, making decisions with incomplete information, taking responsibility for outcomes, building a team, an...
