Rust • PostgreSQL • GraphQL API • Event-Driven Architecture

TBD (Hybrid Interoperability Network)

• Engineering a blockchain-based middleware that enables verifiable and privacy-preserving data exchange across CRM and ERP systems.
• Developing Rust crates for consent management, canonical event definitions, and secure adapter SDKs that bridge off-chain CRM platforms with on-chain verification layers.
• Designing an event-driven interoperability protocol where CRM webhooks are mapped into standardized, ledger-anchored events to ensure auditability and data integrity.
• Implementing selective data anchoring and cryptographic proofs to maintain confidentiality while ensuring end-to-end traceability across enterprise systems.

Rust

Solana

• Design: defined escrow requirements, asset-swap flow, and “pay the difference” logic; modeled contract sequence with UML/flow diagrams.

Rust • Substrate

Chain TBD

• This is part of my PhD research on using blockchain for interoperability between different industries, particularly BIM/ERP systems.

Rust • Solana• Tokio • Geyser

On-chain (Solana)

• Engineered an execution path with leader-schedule awareness and pre-signed, pre-quoted transactions to minimize slot miss risk.
• Implemented risk management algorithms (VaR/ES, Kelly-fraction caps, rolling drawdown guards) with position sizing and circuit-breaker halts.
• Built streaming market data via Geyser/WebSocket with lock-free channels and back-pressure control for deterministic throughput.
• Added health checks, jitter/latency telemetry, and failover across dedicated RPCs with configurable slippage & priority-fee policies.

Rust (Anchor) • Strategy Adapters • Postgres

On-chain (Solana)

• Designed a share-based vault with time-bounded harvests, performance/management fees, and strategy adapters.
• Implemented deposit/withdraw with precise share accounting and oracle-checked price-per-share sanity.
• Built a lightweight keeper to trigger harvests and a minimal UI for deposits and analytics.

Rust • Solana • Telegram SDK for mini-apps

On-chain (Solana)

• Built a high-performance trading bot integrated with Solana’s RPC/Geyser for real-time on-chain data ingestion.
• Implemented strategy-based order routing and transaction prioritization.
• Connected a Telegram bot interface for user interaction, portfolio updates, and trade execution notifications.

Next.js • Solidity • MongoDB

Ethereum-compatible (ERC721A)

• Designed and deployed a factory smart contract that generates optimized ERC721A contracts for each new collection.
• Developed a Next.js frontend for creators to manage whitelists, mint settings, and launch dashboards.
• Integrated MongoDB for persistent storage of project metadata and user configurations.

Solidity • PostgreSQL

Ethereum-compatible (Smart Maintenance)

• Implemented a Solidity smart contract for machine maintenance tracking and automated service scheduling.
• Integrated PostgreSQL backend for off-chain data storage, analytics, and maintenance history.
• Designed on-chain/off-chain interactions for secure asset lifecycle management and auditability.

Solidity • PostgreSQL • Next.js

EVM (Ethereum) with off-chain agents

• Designed a decentralized protocol that routes manufacturing orders to machines using multi-criteria scoring (AHP-based) with on-chain audit trails.
• Implemented automated payment/escrow smart contracts (milestone-based releases, penalties, and SLAs) with cryptographic proofs of completion.
• Built off-chain router agents (Rust) that gather machine telemetry (MQTT/OPC UA), compute rankings, and commit signed decisions on-chain.
• Integrated a Postgres-backed analytics layer and a minimal Next.js dashboard for order status, settlement events, and dispute resolution.
