As a software engineer in product-driving team, I was mostly working with TGTG Platform Donations and TGTG Reports systems – both business-critical systems. • Developed TGTG Donations from Scratch: Built the TGTG Donations system from the ground up, introducing a unique item type using Domain-Driven Design. This solution laid the foundation for future microservice scalability and integration with major retailers like ALDI.• Optimized Item Property Handling: Refactored item property management, reducing database calls by 30% and infrastructure costs by 10%, significantly improving system performance and scalability.• State-Machine for Donations: Implemented an independent state-machine, improving system from the unnecessary scaling with huge God-Classes.• Improved Monitoring & Release Process: Streamlined the monitoring and release process using Grafana and alert systems, reducing production incidents by 40% during pilot releases for high-profile clients such as Starbucks, Burger King, and McDonald’s.• Address Validation and Location Restrictions: Presented a comprehensive solution for address and location validation, designed for business logic that requires precise location data for purchases. The solution was developed after an in-depth analysis of APIs, including Photon, Nominatim, and Google Address API, to ensure accurate, efficient and secure validation and storage of personal data for users.

When the certificates expire, the support team will receive an email in two weeks, due to which the number of unsuccessful deployments in production for this reason will decrease to zero, the number of accidents due to the expired expiration date of the certificate will decrease to zero. • The process of data delivery and validation to the data lake has been implemented: now the system is a data provider to the lake for effective analytics of user actions and further compilation of metrics.
