From a high-level perspective, frontend engineering functions as the translation layer between raw, machine-readable data and human interaction through User Interfaces (UI) and User Experience (UX). While technical optimization often focuses on rendering pipelines, bundle sizes, and state management, comprehensive engineering requires ensuring compatibility across the full spectrum of human capab…

On April 15, 2026, Snap Inc. cut 1,000 jobs — 16% of its entire workforce — and offered a reason no major corporation had stated this directly before: artificial intelligence now generates 65% of the company's new code. CEO Evan Spiegel cited AI advancements enabling the company to "function with smaller teams," projecting $500 million in annualized savings. Snap's public framing was not spin. It…

There was, for a long time, a wall. If you walked into a book store, past the magazines and the cookbooks, you’d arrive at the computer section, and along one wall there was a stretch of books with cartoon animals on their covers. A rhino for JavaScript. A camel for Perl. A python (obviously) for Python. And whatever this was: They were thick, they cost about $50, and they had titles like “Learni…

Who is this for? Mid-to-senior engineers preparing for system design interviews, or anyone curious how a short-video platform at billion-user scale actually works under the hood. Scale We're Designing For Metric Number Monthly active users 1B+ Videos uploaded per day ~34 million Target feed latency (P99) ~167ms Peak egress bandwidth ~26 Tbps 1. Requirements Before drawing a single box, nail down …

The biggest UX mistake in LLM-powered web apps is waiting for the complete response before sending anything. On a 400-token answer at typical generation speeds, that's 4–8 seconds of staring at a spinner. With streaming, the user sees the first word in under a second and reads along as the model generates. This tutorial shows you exactly how to implement token-by-token streaming from an LLM API t…

A real account of building an Async Job Queue with Backpressure & Priority Scheduling using Python, FastAPI, and Redis Streams — covering the Reaper service, 47 tests, 85% coverage, and every bug along the way. No Celery. No shortcuts. No pretending the first approach worked. I decided to build a production-grade project from scratch to bypass the abstraction layer of tools like Celery and truly …

Building a CI/CD Pipeline From Scratch: A Practical Guide for Developers Originally inspired by Akoode's CI/CD pipeline guide — rewritten here with more depth, code, and less hand-waving. I've seen teams spend hours manually running tests, zipping build artifacts, SSHing into servers, and crossing fingers before every deploy. CI/CD pipelines exist to kill that workflow. This guide skips the theor…

Our organization has internal GitHub repositories. We use .NET. We would like to keep production secrets out of source control. At the moment, the developers are aware of the production secrets, but ...

React Server Components are now the default in Next.js and they’re shipping in TanStack Start. Whether you opted in or not, you’re going to encounter them in 2026. The good news: the TanStack approach makes RSCs feel like a tool you can opt-in for instead of a paradigm shift like in Next.js. Let’s look at RSCs in depth - Your component runs on the server. The server sends back the already-rendere…

After nearly 20 years leading teams in hospitality and logistics, I made a career change into software development. When it came time to build my portfolio, I made a deliberate choice: it would not be just a collection of screenshots and technology lists. It would be a working demonstration of how I think about software architecture. This is the story of how I built it, the architectural decision…

Async/Await in JavaScript: From Callbacks to Clean Code (2026) Async JavaScript has come a long way. Here's the complete picture — from callbacks to async/await and everything in between. The Evolution // ERA 1: Callbacks (2010-ish) — The "Callback Hell" getData ( function ( a ) { getMoreData ( a , function ( b ) { getEvenMoreData ( b , function ( c ) { getFinalData ( c , function ( finalData ) {…

Modern Angular applications rarely need just a dropdown. In real projects, a multiselect dropdown usually sits inside something more important: filters, dashboards, reporting tools, permission editors, workflow screens, admin panels, and data-heavy forms where users need to search, group, select, clear, validate, and keep state consistent. That is the context behind Stackline Angular Multiselect …

Physics-based browser games are nothing new, but creating something that feels truly organic, interactive, and sensorily satisfying remains a rewarding engineering challenge. In this technical blog post, we look under the hood of Gravity Paint – a gravity-aware sandbox puzzle where players paint rigid rope cables to funnel a stream of colorful glass, steel, and bubble marbles into an target colle…

The Problem We Were Actually Solving At Veltrix, we're known for our real-time treasure hunts – a complex feature that involves querying a massive graph database, processing high-frequency event streams, and returning results in under 100ms. However, when we started to onboard more clients and scale our infrastructure, our operators consistently hit the same problem: configuring the system to han…

Most n8n AI workflow tutorials end at "it worked in testing." The gap between a demo and a production system handling 10,000 items/day with real money on the line is where the interesting problems live. At Chronexa , we've built 50+ multi-agent workflows for fintech compliance teams, legal document processing, AI SDR engines, and RAG-powered research assistants. Here's what we've learned about ma…

Messaging infrastructure has been boring for a decade. Queues, topics, exchanges — the primitives settled. Then AI agents arrived, and suddenly the assumptions that made messaging boring stopped holding. Messages are no longer just data. They are context. An agent will read your message, reason over it, call tools because of it, and generate responses whose token count you cannot predict at enque…

MIT. 🔗 https://github.com/rogerhokp/tmpdrop 🌐 https://tmpdrop.solardev.online Why another one: public file hosts retain your data on infra you don't control + predictable URLs get scraped. tmpdrop is "0x0.st but on your own box" with a security posture I'm a…

After understanding composition, inheritance, and polymorphism, the next important step is learning how to define clear behavioral contracts between components. This is where interfaces and abstract classes become essential. They help answer one of the most important questions in system design: “What should this component be capable of doing?” without tightly coupling the system to a specific imp…
