– Backend Architecture: Architected and developed high-throughput batch processing pipelines using Spring Batch, handling millions of records for insurance claims, contribution reconciliation, and financial settlements. – REST API Design: Designed and exposed RESTful APIs consumed by front-end applications and partner systems, ensuring proper versioning, security (OAuth2/JWT), and comprehensive Swagger/OpenAPI documentation. – Microservices Migration: Led the migration of legacy monolithic modules to a microservices architecture, improving deployment independence and reducing release cycle times by over 30%. – Database & ORM: Implemented robust data access layers using JPA/ Hibernate with PostgreSQL and Oracle databases, optimizing complex queries and ensuring data integrity across transactional boundaries. – Cloud & DevOps: Collaborated with DevOps teams to containerize applications with Docker and deploy on Kubernetes (K8s), contributing to CI/ CD pipeline definitions via GitLab CI. – Technical Leadership: Participated in code reviews, defined coding standards, and mentored junior developers in best practices for clean code, testing (JUnit, Mockito), and SOLID principles.

– At RAKLESS, I contributed to multiple client projects as a full-stack developer while also supporting AWS cloud infrastructure tasks. I worked across the entire delivery stack — from backend API development to front-end integration and cloud deployment. – Backend Development: Developed and maintained RESTful backend services using Java/Spring Boot, including authentication flows, business logic modules, and third-party API integrations. – Frontend: Built responsive front-end interfaces using Angular, consuming REST APIs and implementing complex data-driven views for client dashboards. – AWS Infrastructure (IaC): Authored Terraform templates to provision and manage AWS infrastructure (EC2, S3, RDS, VPC, ELB, CloudFront, Route 53), significantly reducing manual setup time and ensuring environment consistency. – AWS Services: Configured and managed core AWS services including IAM (roles, policies, MFA), Auto Scaling Groups, CloudWatch alarms, CloudTrail auditing, and SNS notification topics. – Database High Availability: Implemented Amazon RDS Multi-AZ deployments for high availability and automatic failover, and automated database snapshot management with retention policies. – CI/CD: Set up CI/CD workflows using Jenkins with Python and Shell scripts for automated testing and deployment to staging and production environments. – Cost Optimization: Optimized EC2 instance types and EBS volumes for cost-performance balance, contributing to a leaner and more efficient cloud footprint.

– Contributed to a digital transformation initiative for AIRBUS, developing a hybrid mobile application to digitize and streamline the inspection and repair tracking process for Radome components. – Mobile Application: Designed and developed a hybrid mobile application (Ionic / Angular 8) enabling field technicians to log, track, and update Radome repair statuses in real time, replacing paper-based workflows. – Backend API: Built the backend REST API layer to expose repair data to the mobile client, integrating with internal databases and ensuring secure data exchange. – AWS Integration: Integrated the application with AWS services (S3 for document/image storage, Cognito for user authentication) to ensure secure and scalable cloud connectivity from the mobile client. – Agile Collaboration: Collaborated closely with AIRBUS engineers and stakeholders to gather requirements, iterate on UX flows, and deliver a production-ready solution within an 8-month timeline.

– Android Development: Developed an Android application using Android Studio to enable remote management of a client database, providing CRUD functionality and a user-friendly interface for field operators. – Data Management: Designed the local data persistence layer using SQLite and implemented synchronization logic with a remote server via REST APIs.

– Technical Support: Assisted senior developers and engineers on internal IT projects; supported the maintenance of industrial systems and electrical motors during a parallel engineering internship.
