At DXC Technologies, I work on building high-performance backend systems and APIs for digital payment and wallet platforms. I design and implement transactional services that handle millions of wallet transactions with low latency, ensuring accuracy and reliability across distributed systems. My work includes optimizing database schemas, writing efficient queries, and implementing caching strategies to improve performance and throughput. I also set up monitoring, logging, and alerting systems to maintain near-perfect uptime and quickly detect issues. In addition to backend development, I collaborate with frontend teams to integrate APIs into responsive user interfaces, ensuring a seamless experience for end users. My focus is on creating robust, secure, and scalable solutions that can handle high-volume, mission-critical workloads.

At Havicma Logistics, I re-architected the logistics tracking platform to a real-time, event-driven system using Node.js, Redis Pub/Sub, WebSockets, and GEO indexing. This allowed instant location updates for hundreds of concurrent drivers with sub-second latency. I built backend pipelines with hot/cold data storage, reducing database load during peak hours, and deployed scalable infrastructure on AWS with Lambda, API Gateway, S3, and CloudFront. While my focus was backend, I also collaborated on interactive dashboards using React, creating smooth, real-time visualizations for dispatchers. My role involved balancing performance, reliability, and user experience, ensuring the system scales efficiently under heavy usage.

At Mouri Tech, I was responsible for designing and building secure, distributed microservices for fintech applications. I implemented authentication, authorization, and RBAC systems, ensuring compliance and data security. I optimized transaction processing services with Node.js, PostgreSQL, and Redis, reducing latency and supporting high concurrency during peak settlements. I also contributed to frontend dashboards using React, integrating with backend services for seamless user interactions. My work focused on fault-tolerant architectures, idempotent APIs, and scalable CI/CD pipelines, improving throughput and reducing errors, while maintaining high availability for critical financial services.
