I build measurable AI infrastructure, quantitative research systems, and products that make complex models useful.
Speculative OCR decoding for Apple Silicon. An MLX toolkit for DeepSeek-OCR-2, GLM-OCR, and Unlimited-OCR with training-free and neural draft modes, benchmarking, a Python API, and an OpenAI-compatible server.
Python MLX Vision-Language Models Speculative Decoding
A production research terminal for Indonesian equities. Connects IDX data pipelines, technical and fundamental analysis, broker-flow research, screeners, portfolio tooling, paper trading, and AI-assisted workflows.
Next.js TypeScript PostgreSQL Quantitative Finance
An earthquake-survival simulation that teaches through physical interaction. A two-minute Swift Playground combining SpriteKit physics, motion controls, procedural audio, seismic haptics, accessible feedback, and a scored debrief.
SwiftUI SpriteKit Core Haptics Core Motion
Constraint-solved diagrams from olympiad geometry statements. Converts text into a GeometryIR, solves supported constraints with SciPy, emits standalone TikZ, and reports whether the result is exact or a schematic fallback.
Python SciPy TikZ Constraint Solving
A browser laboratory for machine-learning intuition. Makes optimization, clustering, dimensionality reduction, and decision boundaries directly manipulable through real-time visual experiments.
React TypeScript Data Visualization Interactive Learning
Offline-first operations software built around a real Indonesian laundry workflow. Covers receipts, server-verified pricing, ESC/POS printing, scheduled reporting, audit history, and tool-constrained AI analysis. Source is private.
