Hi, I'm Matthew!

I'm a San Francisco-based thinker, writer, technologist, and product strategist with a strong background in design. I collaborate with product teams and entrepreneurs at companies of all sizes, helping them develop and refine their products at every stage of development. My expertise lies in creating innovative consumer and B2B products, optimizing existing features, and working closely with end-users to enhance their experience.

If you have product or design opportunities or want to discuss travel and finance, please don't hesitate to reach out via email. I'm always happy to meet over coffee and explore potential collaborations.


Travel is one of my great enjoyments in life. I love immersing myself in new cultures, meeting people from diverse backgrounds and exploring local cuisines. I document many of my adventures through photos and share my experiences on X. I'm working on the next draft of a travel memoir, where I delve deeper into the stories and insights gained from my journeys.

In addition to travel, I have a strong interest in data science, financial modeling, and algorithmic trading. I am leveraging R and Python to develop trading strategies and explore the potential applications of Machine Learning (ML) in consumer-facing products and services, particularly finance. I have also developed a strong proficiency in trading derivatives, including futures and equity options.

I trade listed and OTC equity options as a discretionary retail options trader. My trades are based on strategies derived from time series analysis and statistical modeling, utilizing paid data from the Nasdaq stock exchange. I am committed to continuously enhancing my understanding of market conditions and trends to make well-informed decisions regarding entry and exit points for each trade. I am developing a comprehensive financial dashboard using Excel, R, and Python to support my trading activities. This tool allows me to monitor trades, account balances, volatility fluctuations, and real-time monetary liquidity.

大家好。 歡迎! 我是孟默修。




我要告訴大家一個秘密: 我❤️台灣。這個小國對我的生活影響很大。我想念自己在台灣有的自由—學習,探索,失敗和發現有關世界的新事物。我可以說是在台灣長大的。
