🎯 My Fun Fact About Myself:
"You know what's wild? I studied physics in university, and I thought I was leaving it behind when I became a frontend engineer. But I'm literally applying physics principles in my code every single day!
When I optimize React rendering cycles and implement lazy loading to achieve those 70% faster page loads I'm so proud of, I'm actually applying the physics concept of conservation of energy — minimizing wasted computational work by only rendering what's necessary, when it's necessary.
Even cooler? My work with WebSocket connections for real-time financial data in those fintech apps uses the same fundamental principles as wave propagation I studied back in school. Data packets traveling through networks follow similar mathematical models to electromagnetic waves!
And that Redux state management I've mastered? It's conceptually similar to thermodynamic equilibrium — maintaining a predictable, stable state across an entire application system, with changes propagating in controlled, deterministic ways.
So I never really left physics — I just found a way more lucrative (and creative) application of it! 🚀⚛️
Bonus connection: My interest in AI/ML (like those Autogon blog posts I wrote) ties back to physics, too — many ML optimisation algorithms are directly inspired by physical systems like simulated annealing and gradient descent (literally borrowed from thermodynamics and mechanics).
Pretty neat how everything I learned connects, right? 😄"
