This Software Engineer Generates $15,000/Month Off the Clock With YouTube, AI Agents, and Mentorship

Ritesh Verma spends 40 hours a week as a software engineer at a major tech firm, but his real wealth is being built between 7:00 PM and midnight. While his day job provides a stable six-figure base, his off-the-clock ecosystem generates an additional $15,000 per month. This secondary income is split across three distinct streams: a YouTube channel focused on engineering deep-dives ($3,500), a suite of AI agent products ($7,500), and a high-ticket mentorship program ($4,000). The journey didn't start with a product, but with a camera; Ritesh began uploading tutorials in 2021, treating his late-night study sessions as content-generation opportunities.

The YouTube channel serves as the top of his marketing funnel, boasting 92,000 subscribers and generating $3,500 a month in AdSense and occasional sponsorships. It wasn’t an overnight success; it took Ritesh 14 months of weekly uploads before the channel crossed the $500/month mark. Today, he maintains the channel on a strict 10-hour-per-week schedule, focusing on high-intent "how-to" content—specifically system design and AI integration—rather than chasing viral trends. This strategy ensures a high CPM (Cost Per Mille) and a steady stream of viewers who are primed for his more expensive offerings.

His most profitable stream is a collection of AI agent templates and custom automation bots sold to mid-sized B2B clients. Leveraging the LLM expertise he refined at his day job, Ritesh built a "plug-and-play" framework that businesses use to automate customer support and lead qualification. He earns $7,500 a month through a mix of one-time license fees and monthly maintenance retainers. By selling to businesses rather than individual developers, he’s able to command higher margins for the same code he writes during his evening hours. It is pure service arbitrage: he takes enterprise-level knowledge and packages it for companies that can’t afford a full-time AI staff.

To round out the $15K total, Ritesh runs a mentorship program for mid-level engineers looking to pivot into AI or break into Big Tech. He charges $500 for a 1:1 strategy session or $2,500 for an eight-week career accelerator. With a time commitment of just five hours per week, this generates a consistent $4,000 monthly. He finds his mentees exclusively through his YouTube comments and LinkedIn, spending zero dollars on acquisition. For Ritesh, mentorship isn’t just about the cash; it’s a feedback loop that tells him exactly what problems the market is facing, which in turn fuels his next YouTube video or AI product.

The $15,000 monthly gross translates to roughly $11,000 net after platform fees and a self-employment tax set-aside. At $180,000 a year in side income, Ritesh has technically surpassed his day job’s base salary, yet he refuses to quit. He views his corporate role as a paid R&D lab where he can stay sharp on enterprise-scale problems that he then "downcycles" into his side projects. It hasn't been a flawless run—a failed SaaS project in 2022 cost him $4,000 in server fees and six months of wasted time—but the diversification of his three streams has created a safety net that no single employer could provide. For Ritesh, the off-the-clock work isn't a hobby; it’s the hedge.
