About Rahul Keswani
I am a passionate and results-driven Software Engineer with over 5 years of experience designing, developing, and scaling high-performance backend systems. I specialize in crafting robust, scalable APIs and microservices architecture that handle millions of transactions efficiently.During my tenure at Twilio, I led the successful design and implementation of the voice costing pipeline, delivering annual savings of $20K and improving costing accuracy by 10% for all voice calls. I also played a key role in the development of APIs and the design of user interfaces to migrate routing management, which resulted in significant savings of $1M/year in third-party contracts. In addition, I have worked on improving the reliability of our services, working across pillars such as deployment quality, availability, incident resolution, and capacity. My expertise extended towards ensuring Twilio\'s compliance and uninterrupted operations in several countries by enabling Emergency calling. I also developed APIs for Twilio’s Interconnect VPN product to unlock self-service, effectively overcoming scalability limitations.I enjoy solving complex technical challenges while delivering solutions that meet business objectives and enhance user experiences.Beyond coding, I thrive on mentoring junior engineers, collaborating across cross-functional teams, and contributing to a culture of continuous learning and improvement.Core skills- Java, Python, Javascript, Dropwizard, AngularJS- MySQL, Redis, Kafka- AWS, Docker, Terraform- Jenkins, JUnit, Mockito, Load testing, Chaos testing- Performance tuning and Scalability
