Designed and implemented a fully automated Personal Environmental Control System (PECS) software platform that integrates IoT hardware (personal heating devices, sensors, controllers) with software-based control logic. Integrated personal heating elements (heated chair, desk mat, foot warmer), and set up reliable communication between hardware and the software platform. Developed an end-to-end automated data and control pipeline, including data ingestion, machine learning, IoT device control, and system logging for monitoring and diagnostics. Evaluated the system's usability and engagement after implementation, with results showing that the interface was intuitive and acceptable for end users.

Built a FinTech platform for trading intellectual property (IP) rights using NFTs on a Substrate blockchain, enabling secure digital asset tokenization and management. Integrated Solana wallet functionality into a React/TypeScript frontend, providing seamless user authentication, asset interaction, and transaction workflows. Contributed within an Agile team environment, delivering features through iterative sprints with active collaboration, code reviews, and continuous feedback. Developed and optimized backend APIs and smart contract interactions, improving system reliability, data flow efficiency, and cross-chain communication. Implemented robust security practices, including wallet authentication flows, safe transaction handling, and data validation to protect users and digital assets.

Engineered and managed a total of 4 MW of solar PV projects: inverter rooms, AC/DC cabling, panel boards installation, and grid connection. Produced AutoCAD SLDs, layouts, cable routing plans, and installation drawings for contractors and grid operators, ensuring clear and buildable designs. Ensured compliance with relevant electrical standards and utility requirements, coordinating protection settings and safe operation. Acted as a technical contact for clients, consultants, and the grid utility, translating design intent into practical site execution.
