Spent my childhood maximizing my portfolio value; now I spend my career maximizing shareholder value.

I have always found that the most consequential decisions live in the tension between data and conviction.

Be it in the equities market, where sole conviction without data can lead to asymmetrical downside risk, or in the boardroom, where a single misjudged assumption can cost millions, I have learned that the ability to navigate this tension is what separates good decisions from great ones.

A dashboard or deck is useless if it only captures the surface. Real leverage comes from exposing the core mechanics of a problem, stress-testing assumptions and risks, and structuring an argument and actionable plan robust enough to drive measurable upside.

My focus is in translating complex environments - unstructured market data, operational bottlenecks, strategic trade-offs — and distilling them into clear, actionable mandates and roadmaps that leadership can confidently back and act on.

Simply put, I'm obsessed with optimization and building efficient systems.

Who I am

I'm a first-class honours Computer Science graduate from Lancaster-Sunway University, majoring in Artificial Intelligence, and I constantly find myself in the intersection of data and strategy.

During my academic life, I have been fortunate to have had the opportunity to work with some of the world's leading organizations, including Citi and L'Oréal, where I gained hands-on experience in data science, analytics, and market intelligence.

Internships aside, I have also been actively involved in leadership roles, having co-led a 50-person committee to the university's Most Outstanding Club Award for non-sport clubs, and founded and directed a team of 16 analysts to form the proprietary research arm of the Sunway Business Investment Society.

I also have a reputation for being the 'go-to' person for anything market-related, specifically in trading and investing. I have been running my own trading portfolio since the age of 15, and have founded several social initiatives in the space. Most famously, I managed to scale an initial capital of RM600 into more than 6-figures from 2020 to 2025, successfully funding a fully paid-for tuition and comfortable lifestyle for present me.

Things worth knowing

  • First and only person from my university to secure internships at both Citi and L'Oréal's data team.
  • Fully self-funded my own undergraduate degree through a trading portfolio I started at 15, which has since grown to more than 6-figures.
  • Founded 2 of the largest online Discord communities of its time in Malaysia during COVID-19, with unprecedented growth and activity during its time.
  • Reported directly to a CFO as an intern, with projects run in front of C-suite and director-level stakeholders.
  • Directed a 17-analyst research team and co-led a 50-person committee to the university's Most Outstanding Club Award.
  • Former state-level debater and public speaker; communicating and articulating my thoughts in high-stakes environments is a skill I take pride in.

  • Identified a gap in the market, twice - and built a solution that successfully scaled to fill it organically.
  • Solo-founded and scaled two of the largest online communities of its time, with unprecedented growth and activity during its time.
  • VALORANT Malaysia reached 8,000 members in four months; The Coffee Shop was one of the most active social servers of its time, with several months of >20,000 messages a day.
  • VALORANT Malaysia was acquired into Riot Games' official VALORANT Asia server, and The Coffee Shop became the fastest-growing MY/SG social server of its era.
  • This was my first real lesson in growth, retention and community incentives, entirely on a whim.

GARCH vs LSTM

Volatility forecasting under a proxy-robust lens

A comparative study of GARCH-family econometric models against LSTM deep learning approaches for forecasting volatility in US equities and ETFs. The real question underneath it: does deep learning actually beat GARCH, or does it only look that way when your volatility proxy is quietly doing the work?

  • Final-year quantitative research and development capstone at Sunway University.
  • Backtests GARCH, EGARCH and GJR-GARCH specifications against LSTM architectures across equity and ETF universes.
  • Proxy-robust evaluation design, built specifically to control for the estimator bias that flatters machine learning models in naive comparisons.

08 — Beyond the résumé

I have a distinct inability to do things casually.

It started at 15 during the COVID lockdowns. While everyone else was hopping on the Dalgona coffee trend, I found myself trading digital commodities (skins) on the Steam Community Market, completely unaware at the time that I was essentially arbitrage trading. I started my trading journey with just RM600 (which I had to beg my parents to lend me), all in the mission for more allowance money. Five years later, that measly RM600 has compounded into fully paid-for tuition and a comfortable lifestyle for present me.

Since young, I've started viewing the word through the lens of game theory and behavioral economics. I was, and am, obsessed with analyzing and predicting human behavior and irrationality, whether it's in the financial markets, competitive gaming, or social dynamics.

This obsession explains why I treat hobbies like competitive sports. I didn't just play video games, I actually grinded to become a top-nation esports player in a game called Brawlhalla and osu!mania. I didn't just play VALORANT, I built the VALORANT Malaysia Discord until the official VALORANT Asia server absorbed us. I didn't just chat on Discord, I founded 'The Coffee Shop' and 'unintentionally' grew it into the region’s fastest-growing server, breaking growth records just to see if I could.

Even my downtime is associated with competition. I used to be really into Chess (1500 FIDE), I was a KL state-level debater (I love adversarial thinking), a competitive programmer (I type and think fast), and a speedcuber (fast hands). When I’m not literally obsessing over the markets, I’m usually trying to bench press 1.5x my bodyweight (100kg @ 67kg) without passing out. I also love having deep, late-night talks and mock debates about existentialism because if we aren't challenging our priors, are we even learning?
