Open-source systems I’ve built to solve real-world problems, from blockchain infrastructure to multi-agent AI.

GENESIS

Autonomous Startup Gauntlet

Training and evaluating LLMs on long-horizon, multi-agent coordination under uncertainty (the real reasons startups fail: planning, communication, morale/runway tradeoffs, and ethical crises).

An OpenEnv-compatible, stateful startup simulation where five role-specialized LLM “co-founders” run a B2B SaaS company via 42 MCP tools. Includes partial observability per role, an adversarial MarketMaker curriculum, personal/ethical crisis scenarios, pivot mechanics, and an 11-term composable reward with a GRPO (TRL + Unsloth) training pipeline and reproducible evaluation artifacts.

Proof of Skill

Time-Locked Skill NFTs

Traditional certifications are static and fail to reflect real-world skill relevance over time, leading to outdated resumes and trust issues in the hiring process.

Proof of Skill is a decentralized, trustless skill verification system built on Solana. It utilizes dynamic, decay-based NFTs that evolve according to user activity, industry trends, and real-world validation. The platform features an AI Skill Auditor that evaluates proof-of-work (like GitHub activity), a permissionless decay engine ensuring skill freshness, and an employer reputation layer for verifiable performance tracking.

A skill token loses value with inactivity. Validated proof-of-work restores it to full.

Decentralized SLA Monitoring

Cryptographic Proof of Uptime

Signed watcher reports hash pairwise into one Merkle root, anchored on-chain.

Service Level Agreement (SLA) monitoring today is centralized and trust-based. Companies must rely on provider-generated uptime reports that are impossible for third parties to independently verify, leading to potential data manipulation and opaque dispute resolutions.

A decentralized protocol for cryptographically verifiable "Proof of Uptime." The system employs a network of distributed watcher nodes that monitor endpoints and sign their findings. These reports are aggregated into Merkle trees to provide efficient inclusion proofs, with the roots anchored on-chain to ensure immutability and public verifiability.

Engineering trust through cryptographic proof.

I’m a 4th year AI & Data Science student who builds decentralized systems. I’m particularly drawn to problems where trustlessness and cryptographic proof can replace institutional middlemen.

I architect protocols across Ethereum and Solana, focusing on systems like decay-based skill NFTs, decentralized SLA monitoring, and trustless credential verification. I design my builds as end-to-end ecosystems where on-chain logic and off-chain data flows remain verifiable.

I’m open to engineering roles and freelance builds in on-chain and AI-agent systems. If you’re building something that replaces trust with proof, or agents that need to coordinate, let’s talk.
