Developed and deployed multiple smart contracts for an online decentralized application using Solidity, focusing on automated financial operations and secure interactions between Ethereum accounts. Designed and implemented financial logic that facilitated continuous value exchange between users, ensuring real-time updates and state consistency on the blockchain. Integrated the smart contracts with a broader dApp architecture, collaborating with the front-end to enable seamless user interactions and blockchain-based functionalities. Built a robust testing framework using TypeScript, in combination with Truffle and Ganache, to simulate real-world transaction flows and edge-case behaviors. Created comprehensive unit and integration tests for smart contracts. Simulated blockchain environments to test payment validation, gas efficiency, exception handling, and access control mechanisms.

Contributed to the development of responsive and user-friendly web applications, primarily using the Angular framework. Worked extensively with TypeScript, JavaScript, HTML, and CSS to build dynamic UI components such as buttons, dropdowns, and modular containers. Led the implementation of internationalization (i18n) features within Angular applications, integrating translation support via JSON configuration files. Structured multilingual data, ensured proper binding of translation keys, and maintained a clean, scalable translation architecture across the app. Created and managed JSON schemas to support efficient data flow and improve data-driven component rendering and validation. Performed functional and regression testing of features developed by the team, helping ensure high-quality releases. Fixed a variety of front-end bugs and UI inconsistencies across different browsers and devices. Utilized Jira for task tracking and Git/Bitbucket for version control, ensuring code quality through structured pull requests and peer reviews.

Managed and maintained structured product data for a commercial website, overseeing the accurate upload, formatting, and categorization of diverse product sets within a web framework. Played a key role in defining and maintaining a clear hierarchy of product categories and subcategories, improving user navigation and overall site usability. Utilized Microsoft Excel extensively to organize large datasets, perform data cleaning, create dynamic tables, and manage content import templates. Applied Python scripts to automate repetitive Excel tasks, such as translating product descriptions, formatting data for web upload, and generating multilingual content mappings. Assisted in the design process by providing content structure feedback, identifying UI/UX inconsistencies, and ensuring alignment between product data and visual layout.
