About me 🍿
Hi, nice to meet you! I’m Tobi — 23, full-time software engineer, CS student, gym fanatic, ex-musician and self-optimization addict. I’m obsessed with building a life that compounds: in knowledge, wealth, health, and relationships.
By day, I work in banking tech, where I’ve helped lead multi-six-figure projects and mentored multiple devs. By night, I study computer science, learn Japanese, train in the gym daily, write, travel and build my freedom — brick by brick.
In the past few years, I’ve:
Self-taught myself to code and landed a fintech banking SWE job
Ranked 1st in my CS class and qualified for academic excellence scholarship while working full-time
Built a six-figure net worth before 23 through disciplined and smart investing
Achieved elite cardio-vascular fitness (40 RHR, 90 HRV)
Accomplished 130kg (290lbs) bench press, 160kg (353 lbs) squat and 60kg (132 lbs) weighted pull-up
Read and applied over 80 books.
Reached Japanese N4 level in 3 months
Learned to play the piano at grade 7/8 with one year of professional schooling
Grown a newsletter from scratch with a 60%+ open rate
As I’m prone to getting stuck in the learning loop, this newsletter gives me an outlet to actively share the ideas in my head.
Why join? 👀
If you're:
Building a better version of yourself

Interested in tech, fitness, finance, or self-mastery
