Developing and maintaining a tourism app using Node.js and React Native where users can book trips and explore travel information. Working on backend APIs, third-party API integrations, and Azure cloud services. Adding new features, fixing bugs, and improving app performance and overall user experience.

– Designed and integrated third-party APIs (payments, communication, external services) with robust authentication, retries, and failure handling, improving API performance by 25%. – Integrated multiple third-party APIs (payments, communication, external services) with robust handling of authentication, retries, failures, and edge cases. – Built and consumed RESTful APIs with efficient endpoint design, validation, and data processing. – Implemented webhook-based architectures for real-time transaction handling, reconciliation, and external system synchronization. – Improved system reliability by 30% through structured retries, error handling, logging, validation, and failure recovery mechanisms. – Delivered AI-powered backend features using OpenAI APIs, embeddings, and RAG-based workflows. – Established CI/CD pipelines using GitHub Actions and Azure DevOps, enabling automated deployments, monitoring, and rollback strategies. – Worked with cloud infrastructure (AWS and Azure) to support scalable deployments, environment setup, and performance optimization. – Collaborated with frontend teams (including React Native) to integrate APIs and support end-to-end debugging. – Took ownership of backend and integration workflows in a fast-paced startup environment, delivering production-ready features with minimal supervision.
