Mr. SeeFun.Dev is a developer channel that has posted at least once a week for 61 weeks straight. Early on it shared a shopping list app built with React and Tailwind, then grew into full-stack builds like Plus and command-line tools like share-env. It also publishes learning guides on seefun.dev subdomains, covering async JavaScript, Linux server administration and a 90-day Backend Mastery roadmap. Between launches come takes on agentic coding and working with AI.

The journey.

  1. Mar – Jun 2025

    React warm-up

    Early posts were beginner-friendly tips, from opening a GitHub pull request to the JavaScript basics worth knowing before React. Then came a shopping list app built with React and Tailwind, plans for a JavaScript course, and the kickoff of a peer-to-peer DSA program.

    Going full-stack

    Plus landed in October 2025: a blog and mini social platform built with React, TypeScript, Node.js, Express and MongoDB. Later posts dug into Next.js server actions, WebSockets, and keeping scheduled jobs running when a server sleeps, trying BullMQ before finding Upstash QStash. In April 2026 came Play Store Submission Auditor, an AI skill that checks Android apps before release.

    A home at seefun.dev

    In May 2026 the channel got its first domain, seefun.dev, and over the next few months filled subdomains with guides to Linux servers, async JavaScript and a 90-day Backend Mastery roadmap. In between it shipped share-env, which encrypts a project's .env files so teams can commit them, and v0.2.0 swapped the shared passphrase for per-teammate keys.

    Agents on WhatsApp

    September brought wappajs, an open-source TypeScript framework for LLM agents on WhatsApp, alongside a post on how repetitive building such agents for multiple projects had become. Lately the feed mixes takes on agentic coding with practical drops like a list of Telegram channels for dev jobs.
