Mathematics Professor
I architect solutions that bridge the gap between complex mathematical models, intuitive web interfaces, and decentralized blockchain ecosystems. We can transform theoretical precision into practical innovation, one equation or one line of code at a time.
Career Highlights
Throughout my career, I've worked with innovative companies across EdTech, Web3, and digital transformation. Some of them includes:
Quizlet
A global leader in educational technology, Quizlet provides AI-powered study tools to over 60 million monthly users, helping anyone learn anything. The platform uses interactive flashcards, adaptive learning algorithms, and gamified experiences to make studying more engaging and effective.
My Contribution
Expert contributor in STEM subjects like Mathematics, Computer Science and Physics.
SkyTrade
Positioned at the forefront of DeFi, SkyTrade is building a decentralized marketplace for high-value, real-world assets through blockchain-based fractional ownership.
My Contribution
Worked with cross-chain protocols like LayerZero and Wormhole to integrate decentralized applications (dApps) across multiple blockchains like Solana and Ethereum.
Avanxia
Avanxia is a strategic technology partner that specializes in creating custom software solutions and modernizing systems to accelerate business growth for their clients.
My Contribution
Leader full-stack developer. Building web platforms with AI features including services like chatbots trained to the business needs.
Development Stack
My go-to programming languages and frameworks for building everything, from responsive web apps to smart contracts and decentralized finance protocols.
JavaScript (ES6+)
TypeScript
React
Next.js
Tailwind CSS
Zustand
React Query

Mathematical Foundations
My background in mathematics provides a unique lens for problem-solving, optimization, and logical architecture.
Calculus
Continuous change, limits, derivatives, and integrals.
Application in Code
Used in the TWAP oracle: exponentially-weighted rolling averages apply continuous decay functions to neutralize last-minute price manipulation.
Series & Sequences
Convergence, divergence, and weighted infinite sums including Fourier and Taylor series.
Application in Code
The manipulation-resistant TWAP assigns geometrically decaying weights to historical price observations using a discrete exponential series.
Linear Algebra
Vectors, matrix transformations, and systems of linear equations.
Application in Code
Foundational for understanding elliptic curve cryptography underlying Solana transaction signatures and key derivation.
Differential Equations
Ordinary and partial differential equations modeling rates of change in dynamic systems.
Application in Code
Provides the mathematical intuition for reasoning about token price dynamics and decay rates in on-chain DeFi protocols.
Algorithms & Complexity
Algorithm design, time and space complexity analysis, and computational optimization.
Application in Code
Applied in Solana program optimization: compute unit budgeting and efficient Merkle proof verification in the cNFT fractionalization protocol.
Discrete Mathematics
Logic, combinatorics, graph theory, and cryptographic primitives.
Application in Code
Directly used in Merkle tree structures for compressed NFTs, Keccak256 leaf hashing, and PDA derivation logic.
