Started collecting songs in 2018. Now it's 750+ tracks. EDM, pop, and whatever hits different at 2 AM. My PUBG squad knows this playlist by heart. Those first 15 minutes before any fights? We'd all play music on our phones. Pure vibes. Good times.

At home I blast this on my TV. Roommates don't care, I don't care, we all win. Late nights I grab my Bose headphones, open eqMac, hit that Clear Bass preset, and code for hours. That's my zone.

August 12th was my first concert. The Weeknd. The crowd was insane. The energy was unreal. If he tours near you, just go. Don't think about it.

750+ songs and counting. Yeah I have a problem. Not fixing it.

I spent years learning 8+ hours a day. Not because someone told me to. Because I couldn't sit still knowing there was something I didn't understand yet.

Stock market models. Facial auth. Legal AI. Fintech agents. Civic dashboards. Cloud infra. OAuth platforms. Every time I finish one thing, I need to know what's next. That's not a flex - it's just how I'm wired.

I don't want to be known as "the AI guy" or "the data guy." I want to be known as someone who can pick up any hard problem and ship something real.

The Director of Analytics at one company once told me he'd show my documentation to his interns as the standard to follow. That landed. That's why I keep going.

Covered most of Tennessee's top state parks by now. Camping became my thing.

Started rough though. First trip in 2023 with 5 friends. None of us had camping experience. Didn't check weather properly. It was hell. Cold, unprepared, complete disaster.

Learned fast. Got proper gear. Tent, sleeping bag, the works. Now camping is where I find peace.

Best part? Cooking my own food out there. Bring chicken, marinate it under the trees, smoke it over wood fire. That taste hits different. Nothing like food cooked over real wood. Wallah, it's superb.

My goal? When I'm financially stable, camp every weekend. That's the dream.

Here's what camping taught me. Switch off your phone for 24-48 hours. Just you and nature. Risky? Maybe. Worth it? Absolutely.

When you turn the phone back on, everything's normal. Few missed calls but people figured it out without you. World kept moving. Nobody actually needed you as much as you thought. Feels like watching life happen while you were dead. Humbling.

Nature teaches you to be alone, grow alone. Shows you what matters and what doesn't. Best therapy there is. We forget to enjoy it. I'm not making that mistake.

Rohan consistently displayed technical proficiency, problem-solving ability, and initiative. His contributions had measurable positive impact on project velocity and code quality. I strongly recommend him for future engineering roles - his blend of technical skill, curiosity, and collaborative spirit will be an asset to any team.

Thank you for all of your hard work so far! It has been a busy start and I appreciate your willingness to jump in and try and build new things. I'm excited to continue watching you grow and develop into a full developer role at Visalaw.
