clim8 is a weather app with a backend proxy pattern that keeps the API key off the client entirely. The Node.js + Express server handles a two-step flow — first geocoding the city name, then fetching weather data from OpenWeatherMap — before returning clean JSON to the frontend. Deployed on Vercel with custom routing config. Simple concept, but the architecture reflects a real security principle: the browser should never see credentials. That's not something most tutorial weather apps bother to get right.

How AI Is Changing Full-Stack Development

AI is no longer just a tool for automation. It is becoming a real partner in software development.

As a full-stack developer, I use AI to speed up planning, improve code quality, generate ideas, debug faster, and build smarter user experiences. But the key is not blindly copying AI-generated code. The real value comes from understanding the logic, reviewing the output, and using AI to support better engineering decisions.

Modern products are moving toward AI-powered features like chatbots, recommendation systems, smart search, workflow automation, and personalized dashboards. Developers who understand both full-stack engineering and AI integration can build faster, more scalable, and more useful products.

AI will not replace strong developers, but developers who use AI properly will move much faster than those who do not.

Arrow Markets is a Web3 options trading platform built around crypto derivatives. In simple words, it helps users trade options on crypto assets with a smoother UI than traditional DeFi trading platforms.

From their site, Arrow is a hybrid Web3 options platform: pricing/hedging is handled through market makers, while ownership, transfers, creation, and settlement happen on Avalanche C-Chain. They also use an RFQ / Request for Quote model, where traders can request quotes from market makers in one click. On the frontend side, I worked on creating clean and responsive interfaces for trading-related screens, focusing on usability, performance, and a smooth user experience. Since options trading can easily become confusing, one of the main goals was to make the platform feel approachable while still supporting advanced trading behavior.

On the Web3 side, I worked with wallet connection flows, blockchain interactions, transaction handling, and smart contract integration. The platform connects DeFi trading logic with on-chain settlement, so reliability and clear user feedback were very important.

This project was especially interesting because it combined several difficult areas: financial UX, decentralized trading, smart contracts, and real-time trading interactions. I enjoyed working on it because it was not just a normal website, it was a real Web3 product where frontend quality, contract integration, and user trust all mattered.
