Building Secure & Decentralized Applications
A multi-chain blockchain developer specializing in Solana (Anchor) and NEAR Protocol smart contracts. I build robust DeFi, DAO, and real-world asset applications, open-source Rust tooling, and AI-powered applications across the decentralized ecosystem.
Featured Projects
Secure Escrow Smart Contract
A trustless escrow program built with Anchor that enables secure transactions between two parties. The contract locks funds in a Program Derived Address (PDA) vault, which are only released upon the buyer's approval or cancellation.
Key Features:
- PDA-based vault for fund security
- Buyer approval and cancellation logic
- Optional deadline for automatic cancellation
- Comprehensive error handling for safety
Tech Stack:
DAO Governance & Voting Program
An on-chain governance program allowing holders of a specific SPL governance token to create and vote on proposals. Voting power is directly proportional to the user's token balance, ensuring a fair and decentralized decision-making process.
Key Features:
- Token-weighted voting system (1 token = 1 vote)
- Proposal creation with description and deadline
- Secure voting mechanism preventing double votes
- Automated proposal finalization and winner selection
Tech Stack:
Ina: Journal & NFT Minting
A multi-chain application that allows users to create journal entries with emotional tags and mint them as NFTs. Originally built on NEAR, the smart contracts were later ported to Solana to expand its ecosystem reach.
Key Features:
- Create public or private journal entries
- Tag entries with moods (e.g., Happy, Sad, Confident)
- Mint journal entries into permanent NFTs
- Cross-chain deployment (NEAR & Solana)
Tech Stack:
Solana NFT Staking Program
A foundational Solana program for NFT staking, built with the Anchor framework. It allows users to stake their NFTs to earn rewards, providing a secure and extensible basis for NFT-based DeFi applications.
Key Features:
- Securely stake and unstake NFTs
- Claim rewards earned from staking
- Modular design for custom reward logic
- Built with Anchor for enhanced safety
Tech Stack:
Chain Call – Solana Smart Contract UI
A non-technical, user-friendly interface for testing and interacting with Solana smart contracts. Designed to lower the barrier for developers and non-developers alike to call on-chain programs without writing code.
Key Features:
- Intuitive UI for invoking Solana programs
- No code required to test smart contracts
- Live feedback on transaction results
- Wallet integration for on-chain interactions
Tech Stack:
IronClaw – Discord & GitHub Integration
Open-source contribution to IronClaw, a secure personal AI assistant built in Rust (NEAR AI). Implemented a Discord channel (WASM component) with slash commands, button interactions, thread support, and rich embeds, plus a GitHub tool for full repository and PR management — both following the existing capability-based plugin architecture.
Key Contributions (merged PR #34):
- Discord WASM channel: slash commands, embeds, threads
- GitHub tool: repos, issues, PRs & workflow management
- Both follow IronClaw's sandboxed WASM plugin model
- Followed up with Discord feature-parity issue (#76)
Tech Stack:
NEAR Fungible Token (near_ft)
A NEAR Protocol fungible token smart contract implementing the NEP-141 standard. Provides a fully on-chain token with minting, transfer, and allowance mechanics, suitable as a foundation for DeFi or governance token systems on NEAR.
Key Features:
- NEP-141 compliant fungible token
- Minting, burning, and transfer logic
- Storage deposit management
- Compatible with NEAR DeFi ecosystem
Tech Stack:
CAFX – High Throughput Trading Platform
A high throughput trading platform built with Rust and Python, designed for speed and reliability in high-frequency trading scenarios. The platform leverages Rust's performance characteristics for critical execution paths and Python for flexibility in strategy and data processing.
Key Features:
- High throughput order processing engine
- Low-latency execution via Rust core
- Python-based strategy and analytics layer
- Scalable, production-ready architecture
Tech Stack:
Real Estate Smart Contract (NEAR)
A NEAR Protocol smart contract enabling trustless real estate transactions on-chain. Deployed on NEAR testnet as shedasolution.testnet, it handles property listing, ownership transfers, and escrow logic without intermediaries.
Key Features:
- On-chain real estate property listings
- Trustless ownership transfer and escrow
- Deployed on NEAR testnet (shedasolution.testnet)
- Transparent transaction history via NEAR Explorer
Tech Stack:
Solana Token Prediction Platform
A prediction platform for Solana tokens that lets users forecast price movements and token performance. Combines on-chain data with an interactive UI to surface market insights and community-driven predictions.
Key Features:
- Token price prediction and forecasting
- On-chain Solana data integration
- Community-driven prediction market
- Real-time market insights dashboard
Tech Stack:
Faschcom
A web platform built and maintained by Penivera. Delivers a responsive and accessible user experience tailored to its audience with a clean, modern interface.
Key Features:
- Responsive, mobile-first design
- Modern full-stack architecture
- Performant and scalable backend
Tech Stack:
telegram-rs-2
A Rust library crate for the Telegram Bot API, published on crates.io. Provides an ergonomic and async-friendly interface for building Telegram bots in Rust, supporting message handling, inline queries, callbacks, and rich media.
Key Features:
- Async-first Telegram Bot API client
- Message, callback, and inline query support
- Rich media and file handling
- Published on crates.io for public use
