AI Fintech Analytics SaaS
Clean work. I like how the product brings AI, analytics, and fintech data into a focused experience instead of treating them as separate features. My background is in full-stack SaaS, dashboards, integrations, and responsive product interfaces, so this is close to the work I...

A few things we’ve been working on this month.
Different industries, different problems, but the same goal: making complex products feel simple, clear, and trustworthy.
Fintech → Investment Banking → Geospatial AI
More projects are still in progress.
Full case studies coming soon.
This is the kind of work I enjoy seeing — simple, focused, and actually thought through.
A watch movement lifted from one photograph into 3D. HEXANOX is an independent horology institute. We certify mechanical movements by measurement, amplitude, beat error, positional variance, to tolerances your eye cannot see.
I built this project to test A watch movement lifted from one photograph into 3D. HEXANOX is an independent horology institute. We certify mechanical movements by measurement, amplitude, beat error, positional variance, to tolerances your eye cannot see. The core engineering challenge was sustaining uncompromised 60 FPS rendering using Three.js (GLB 3D) while handling continuous user interaction without framework overhead.
WHAT I WAS TESTING:
I focused on two core engineering benchmarks:
Precision implementation of image → GLB under continuous interactive user input
Sustained 60 FPS render performance and zero-dependency browser execution
THE TECHNICAL SIDE:
Engineered directly in the browser with Three.js (GLB 3D), WebGL / GLSL Shaders, Canvas2D, Image → GLB. The application runs without third-party frameworks or build-step dependencies, using hardware-accelerated rendering and custom event loops to achieve zero-latency response.
Everything executes in the browser using Three.js (GLB 3D), WebGL / GLSL Shaders, Canvas2D, Image → GLB. No third-party frameworks, no heavy runtime bundles, and zero external tracking.
WHAT I LEARNED:
Balancing the mathematical rigors of image → GLB with tactile browser interaction required tuning event throttling and memory allocation to eliminate all garbage collection stutters.
Finding the sweet spot between mathematical precision and frame budget took careful profiling, but the result runs at a steady 60 FPS even on modest hardware.
TRY IT YOURSELF:
The live build is deployed on Netlify. Open it in your browser, test the controls, and observe the render response times.

An interlocking gear-train workbench with true ratios and brass-blueprint charm.
I built this project to test An interlocking gear-train workbench with true ratios and brass-blueprint charm. The core engineering challenge was sustaining uncompromised 60 FPS rendering using Canvas2D while handling continuous user interaction without framework overhead.
WHAT I WAS TESTING:
I focused on two core engineering benchmarks:
Real-time gear mesh torque transfer and escapement tick mechanics
Interactive placement of interlocking brass gears with variable ratios
THE TECHNICAL SIDE:
Implements true involute tooth profiles computed via parametric equations. Rotational speeds are propagated through an adjacency graph of connected gear nodes.
Everything executes in the browser using Canvas2D, Mechanical Gear Physics, Involute Gear Tooth Profiles. No third-party frameworks, no heavy runtime bundles, and zero external tracking.
WHAT I LEARNED:
Floating-point precision drift caused gear teeth to gradually overlap after several minutes. Clamping phase angles to gear pitch intervals solved the drift.
Finding the sweet spot between mathematical precision and frame budget took careful profiling, but the result runs at a steady 60 FPS even on modest hardware.
