As a Python Backend Developer, I enjoy turning complex business workflows into clean, reliable APIs and services that actually make life easier for end users and operations teams. Over the past few years, I have worked on delivery management, alumni management, and automated attendance systems, focusing on correctness, performance, and maintainability.​​ At FlexiApps, I design and build backend systems using Django, Django REST Framework, and relational databases like MySQL and PostgreSQL for an Enterprise Delivery Management (EDM) platform. My work has included multi-role user onboarding (organization, shop, agent), route and vehicle management, delivery execution and tracking, and reporting features such as payment summaries and agent performance dashboards, all exposed through well-documented REST APIs. I pay particular attention to validation, pagination, and filtering so that the system remains robust and efficient as data grows.​​ Previously, I gained experience as an Programmer Analyst at Cognizant, building solutions on SharePoint and K2, which strengthened my understanding of enterprise environments, stakeholder communication, and disciplined testing Academically, my Master’s in Computer Science (Passau, Germany) focused on data analysis, machine learning, and text mining, and I have applied those skills in projects involving style change detection and sensor-based prediction.​​ Technically, I am comfortable with Python, Django/DRF SQL (MySQL/PostgreSQL),and theoretical knowledge in FastAPI, Flask, MongoDB, JavaScript, HTML/CSS,. I also have hands-on experience with machine learning (MTCNN, ResNet-based embeddings) and data analysis, which helps when building data-intensive features or integrating intelligent components into backend systems. I enjoy working in collaborative environments, doing code reviews, iterating quickly, and using tools like Git and modern CI/CD practices to keep delivery smooth.​​ Currently, I am looking to connect with teams that are building scalable backend systems, SaaS platforms, or logistics and operations tools where Python and Django play a central role.
