Spearheaded a cross-functional development team in migrating two legacy Ruby on Rails applications to Java Spring Boot, ensuring architectural alignment and code quality standards throughout the migration lifecycle. Designed and implemented comprehensive migration roadmap, identifying dependencies, risk mitigation strategies, and phased delivery approach to minimize business disruption. Owned end-to-end delivery of multiple project milestones as technical lead, including requirement analysis, code refactoring, API compatibility layer development, and post-migration validation. Served as primary technical liaison with HP stakeholders, facilitating requirement clarifications, providing technical recommendations, and conducting regular sprint reviews to ensure alignment with business objectives. Established coding standards, conducted code reviews, and created comprehensive technical documentation to support knowledge transfer and ensure maintainability of the migrated codebase. Provided technical guidance and mentorship to team members on Ruby on Rails best practices, migration patterns, and cross-platform development considerations.

Built a secure, scalable, and user-friendly online fee collection system to automate the financial operations of educational institutions, reducing manual effort and enabling real-time digital payments. Lead the end-to-end development of the online fee payment module, from system architecture and design to testing and deployment in production environments. Integrated Razorpay and NTT Atom APIs, implementing payment request flows, callback handling, webhook authentication, and error retries to ensure high success rates and secure processing. Built a robust transaction management system with support for partial payments, refunds, fee waivers, and automatic payment status updates mapped to student fee ledgers. Developed a fully responsive admin dashboard to manage and monitor real-time transaction history, reconciliation reports, and fee configuration settings. Implemented background jobs using Sidekiq to handle asynchronous processing of receipts, fee due reminders, and failed transactions retry logic. Ensured PCI-DSS compliance for secure handling of payment data by offloading card input handling to the gateways and implementing strong parameter sanitization. Collaborated with the finance team to define business logic around fee categories, due dates, discounts, penalties, and notifications for overdue payments. Built export-ready reports in CSV and PDF formats for account reconciliation and audit compliance. Conducted UAT (User Acceptance Testing) with finance admins and resolved edge case issues in production.

Developed a full-featured transport management system to streamline the assignment of students to transport routes, track logistics, and automate fee calculation for educational institutions. Designed and implemented a modular CRUD interface for managing vehicle fleets, routes, drivers, and student-to-route allocations with validations and filtering options. Enabled dynamic assignment of students to routes based on location proximity, pickup points, and vehicle capacity. Created a route planner that supports one-way and round-trip configurations, multiple stops, and optional guardian contact info at each stop. Implemented route-wise and distance-based fee logic configurable per batch or student, including discounts and sibling adjustments. Developed real-time schedule management for updating pickup/drop-off times, rerouting vehicles, and communicating delays to parents via in-app and email notifications. Integrated Google Maps API (optional) for visualizing routes and distance calculations. Built admin-side reporting tools to view current allocations, route occupancy, fuel efficiency metrics, and driver performance. Enabled CSV exports and reports for student transport allocation, vehicle logs, and route-wise earnings for the finance department. Ensured data integrity by enforcing driver-license validations, vehicle capacity checks, and route-overlap prevention. Collaborated with school transport coordinators to test and roll out the module, iterating based on real-world logistics constraints.

Engineered a flexible and scalable gradebook system to support academic performance tracking across subjects, exams, and terms for K-12 institutions. Designed and implemented a dynamic gradebook module that supports both term-based and year-round assessments, catering to diverse grading systems across institutions. Developed mark entry forms with auto-save, bulk upload (CSV), and dynamic input validation to reduce human error and streamline teacher workflows. Automated the calculation of grades, GPAs, and class averages based on configurable weightages per subject, exam type, and grading policy (absolute/relative). Built logic for custom grading sets, supporting multiple types such as letter grades (A-F), percentage, pass/fail, and GPA scales. Created a template-driven report card generator, enabling administrators to design school-branded reports with logos, signatures, remarks, and student performance summaries. Integrated Prawn and WickedPDF for exporting report cards in print-friendly PDF format, supporting batch exports and multilingual content. Built performance dashboards for students, teachers, and parents visualizing academic trends using charts, rankings, and historical comparison across terms. Added fine-grained access control for viewing/editing marks, ensuring only authorized users (class teachers, subject teachers, admins) could modify records. Maintained data integrity by enforcing subject-to-batch mappings and validation rules on mark entry for unassigned subjects or students. Conducted functional testing with QA and teaching staff and gathered real-time feedback to refine usability and features.

Engineered a real-time attendance monitoring and communication module to improve student tracking and parent engagement in academic institutions. Developed daily, subject-wise, and event-specific attendance tracking workflows, supporting both individual entries and bulk updates for entire batches. Implemented validations to prevent duplicate entries, out-of-schedule logs, or unauthorized attendance manipulation. Built admin-side tools for configuring working days, holidays, attendance thresholds, and manual override permissions. Integrated in-app notifications and email alerts using AWS SES and SMTP, enabling automatic updates to parents and teachers about absences, late arrivals, and attendance summaries. Designed a notification preference system allowing users to opt-in/out of specific alerts (daily, weekly, monthly). Scheduled background jobs via Sidekiq to send automated reports every morning and after school hours, reducing the need for manual communication. Implemented an audit logging system to track who made changes to attendance records, along with timestamps and reasons for modification. Enabled dashboard visualizations for tracking attendance trends, absentees, and defaulters across time periods. Conducted QA and feedback sessions with school staff to align the module with real-world classroom and admin practices.

Worked on a scalable LMS platform designed to empower institutions and organizations to deliver, manage, and track learning experiences for learners globally. Built and enhanced core LMS modules including course creation, lesson delivery, quizzes, and certificate generation. Implemented role-based access control for admins, instructors, learners, and organization managers. Developed dynamic content upload mechanisms supporting videos, documents, SCORM packages, and assessments. Integrated real-time progress tracking and completion analytics for learners and organizations. Created RESTful APIs to support mobile and third-party integrations with the Uzity platform. Worked on UI/UX enhancements using HTML, CSS, and JavaScript to improve learner engagement. Implemented email notifications, in-app messages, and reminders using Sidekiq background jobs and ActionMailer. Collaborated with QA and product teams in Agile sprints to rapidly prototype and iterate on new features.
