Factory Method Design Pattern in Software Engineering: A Smarter Way to Create Objects

Introduction As software applications grow in size and complexity, managing object creation becomes challenging. Creating objects directly using constructors can result in tightly coupled code that is difficult to maintain and extend. The Factory Method Design Pattern solves this problem by separating object creation from object usage. It provides a flexible and reusable approach for creating obj...

Design First, Then Build: A Better AI Dev Workflow

The Scenario Every Developer Recognizes It is mid-2026, and you have a feature to ship. You open ChatGPT or Claude, type something like "build me a function that parses webhook payloads and routes them to the right handler," and wait. The model returns something plausible. You paste it in, run it, and it almost works. So you prompt again: "fix the edge case where the payload is missing ...

How Pokemon IVs Are Calculated Under the Hood — A Reverse Engineering Guide

If you've ever wondered whether that wild Pokemon you just caught has competitive potential, you've probably heard the term IVs (Individual Values) thrown around. IVs are the hidden genetics of every Pokemon — the 0–31 numbers baked into your Pokemon at birth that determine how strong it can ultimately become. But here's the thing: the game never tells you what your IVs are. You have to reverse-e...

I Built a Photo-to-Cross-Stitch Pattern Maker That Runs in Your Browser

Photo-to-cross-stitch conversion looks like a resizing problem. It is not. A pixelated preview can look convincing and still be frustrating to stitch. It may contain too many colors, lack readable symbols, provide no reliable dimensions, or become useless when printed. I built StitchFromPhoto to handle the practical part of that workflow. It turns an image into a counted cross-stitch chart in the...

Traceroute devlog #3

Most of this week's difficulty lived inside one single rule, and what made it worth writing about isn't any one fix — it's that I didn't actually understand the problem until I'd already "solved" it three times. The rule sounds small: if you click through a point on your own path that would carry you past your color's still-unreached endpoint, the path should stop right there and count as done. T...

Why Claude-generated screens are missing their states

Ask for a screen and you get the screen on its best day. Full of content, nothing loading, nothing failed, permission already granted, network fine. The product as it appears in a case study rather than as it appears on a Tuesday. This gets described as a limitation of the model. I think it's more specific than that, and the specificity is useful. It learned from portfolios Nearly eve...

LiveAvaBot Developer API: Embed Telegram Video Avatar Conversion in Your App

I built @liveavabot last year to fix a stupid problem: iPhone videos silently fail as Telegram video avatars. The bot has processed conversions for 290 users so far, and a few of them asked the same question: "can I hit this from my own code?" So I shipped a REST API. This post walks through the Telegram spec that makes video avatars weird, the ffmpeg pipeline that solves it, and how to call the ...

Getting Typed JSON Out of LLMs: Field Notes on generateObject

Headline: The Vercel AI SDK's generateObject is the reliable way to get typed, schema-validated JSON out of a language model: I pass a Zod schema, the SDK constrains the model and validates the result, and I get a typed object instead of hand-parsing a string that is JSON most of the time. Four things carried the weight for me — generateObject for one-shot extraction, streamObject for progressive...

Beyond LeetCode: Why Tasting Code Beats Memorizing Algorithms in the Age of AI Agents

Originally published on tamiz.pro. The whiteboard interview is dying. Not because interviewers have suddenly developed a conscience, but because the fundamental unit of software engineering has shifted beneath our feet. For two decades, the industry standardized on a specific type of cognitive load: the ability to mentally manipulate data structures and implement sorting or graph traversal algori...

Prototype & Factory Method Design Patterns in Java - ClauseGuard

Introduction When ClauseGuard processes an uploaded contract, two problems appear immediately at scale. First, it needs to pick the right document parser -- PDF or DOCX -- without hardcoding that decision into business logic. Second, it needs to stamp out hundreds of clause objects fast without reconstructing them from scratch each time. Prototype and Factory Method are two classic Gang-of-Four cr...

The "Minimum Viable System": How to Ship Early Without Shipping Junk

There is a dangerous piece of advice in software development: "Just build an MVP." It sounds reasonable. Build the smallest possible version. Launch quickly. Get feedback. Improve later. The problem is that many developers interpret "minimum viable product" as: Remove everything. Skip architecture. Ignore security. Ignore testing. Hardcode everything. Ship it. Then six months lat...

6 Sports Fan Engagement Companies Worth Watching in 2026

Sports fan engagement has a software problem. Most clubs don't lack digital tools. They have too many of them. Memberships live in one system. Ticketing lives somewhere else. Payments are handled separately. Match-day engagement might be another app. Fan communication is often disconnected from all of it. That creates a strange situation: clubs can have more digital touchpoints than ever while ...
