Live match score-prediction platform

Full-stack · solo build

Problem

Casual football fans had no lightweight way to predict live match scores and compete with friends in real time. Existing sites were heavy, account-walled, and slow to reflect what was happening on the pitch.

Solution

A Next.js platform that syncs live match data on a schedule via Vercel Cron, runs prediction and leaderboard logic against MongoDB, and serves a responsive Tailwind UI that updates as matches progress.

Impact

Cut bet-settlement processing time by ~60% with parallel processing + server actions. Live scores and player stats sync from the api-sports.io API on a Vercel Cron schedule — no manual data entry.

Cableless device-to-device file transfer

Full-stack · solo build

Problem

Moving files from a PC to a phone usually means a cable, a shared account, or uploading to a third-party cloud — slow, clunky, and not great for privacy.

Solution

A web app that pairs two devices into a room and streams files directly between them peer-to-peer via peer.js (WebRTC) — right in the browser. No installs, no cable, no cloud middleman holding your files.

Impact

Guaranteed transfers up to 2 GB across Windows, macOS, and Android — cross-platform, with nothing persisted server-side.

AI text-to-image generator SaaS

Full-stack · solo build

Problem

Standing up an AI image generator usually means wiring auth, a model API, image storage, and a gallery from scratch — a lot of plumbing before you can type a prompt and see a picture.

Solution

A lightweight Next.js 15 SaaS that turns text prompts into images via the Clipdrop API, with JWT auth + middleware-guarded routes, prompt/history in MongoDB Atlas, generated images on ImageKit, and a smooth animated gallery.

Impact

A full end-to-end SaaS in one build — sign-in, generate, and a responsive gallery (style + timestamp) — architected to extend to credits, payments, and multi-user later.
