The “Slash” Life: Data, Dhamma, and the Art of Living
In a world that constantly asks us to “pick a lane,” I’ve chosen to build a multi-lane highway. My journey is about creating order and space—whether that’s digital, physical, or mental. From the precision of Data Science to the practicalities of Property Stewardship (including my years as an Airbnb Superhost), and from the wisdom of Buddhist Dhamma to the serenity of Yoga, every path I walk informs the others.
My life is an ongoing exploration of how diverse passions—like analyzing complex datasets and teaching ancient philosophies—don’t just coexist; they enrich and empower one another. Welcome to my world, where every “gig” is a step on a continuous path of learning, serving, and living fully.

In the world of data visualization, color is more than just an aesthetic choice—it’s a communication tool. However, common color models like RGB and HSL often fail us because they aren’t “perceptually uniform.” This means that while the math behind the colors is consistent, our human eyes perceive some transitions as harsher or brighter than others, potentially leading to misinterpretation or accessibility issues for those with color blindness.
Enter the HCL (Hue-Chroma-Luminance) color space. Unlike its predecessors, HCL is designed specifically to align with human visual perception. By separating color into Hue (the tint), Chroma (the intensity), and Luminance (the perceived brightness), HCL allows designers to create palettes where every step is visually equal. This ensures that your charts remain readable, professional, and accessible.
Whether you’re building complex heatmaps or simple bar charts, switching to an HCL-based workflow is the most effective way to ensure your data is seen—and understood—exactly as you intended. Stop letting “bad math” distort your data and start using a color space built for the human eye.

“No one likes you naked” is a quiet truth at the heart of samsaric suffering. What the world rewards is not who we are, but what we emit—crafted identities, agreeable projections, performances shaped for acceptance. While we struggle to preserve these images, nature moves in chaos, undoing every construction. This resistance creates dukkha. The Buddhist path does not ask us to perfect the mask, but to see through it. Liberation begins not by pleasing others, but by saving oneself from endless becoming.
