Architected and executed a backend rewrite of object and block storage platforms to eliminate vertical scaling bottlenecks inherent in aging hardware and legacy software. This decisive action mitigated resource limitations and unlocked horizontal scalability potential. Architected and implemented a microservices-based platform for billing, usage metering, and subscription management, while ensuring PCI Data Security Standard (DSS) compliance. ### Technical Team Lead @ Tellabs Jan 2010 – Jan 2015 | Santaclara,ca Headed the architecture for Security infrastructure and hardening the gateway (LTE and Wimax). This involved working across various cross functional business units. Focus on buffer overflow, starvation and resource contentions. Fixed various deadlocks in the IP stack/network data path in the kernel. Implemented the Network Monitoring and Maintenance system (NNMS), which monitors all the gateways in the customer network, if any issues found during the health check, corrective action is taken by the NMMS based on the severity of the issue. KPI based management of the wimax gateway is also handled by NNMS. Improved the overall code to provide 400 days MTBF from less than 72 hours of MTBF. Received "Tellabs Excellence Award" for my contribution. ### Senior Software Engineer @ Access Systems americas Jan 2006 – Jan 2010 As a Senior software Engineer I am responsible for design and implementation of various features for ALP (Access Linux) based mobile devices. I took a lead role all the way from developing code for booting of the device, power management, power management drivers, tactile feedback drivers, volume services and Security Policy Framework for ALP. Lead the team with being hands on for fine tuning of performance (smart phone/mobile devices), profiling, stability and security of the device. ### Senior Software Engineer @ Real-Time Innovations Jan 2004 – Jan 2006 •Re architected the Heart Beat protocol related issues in the RTPS protocol (Real-Time Publish-Subscribe Wire Protocol). •Designed, developed and integrated to various platforms, Condition and Waitset feature •Designed and implemented publisher wait for acknowledgments feature •Extended capability of listener mechanism. Listener provide a generic mechanism for the middle ware to notify the application of relevant asynchronous events, such as arrival of data corresponding to a subscription, violation of a QoS setting, etc. •Received “Hero Awards” for my contribution to DDS features. ### Senior Software Engineer @ Cisco Jan 1995 – Jan 2004 Worked on Security infrastructure for routers. Worked on High Availability. Involved in reliability and scalability. Designed and implemented various modules for IOS kernel. Worked on Memory Management infrastructure. Router boot and initialization. Implemented non-preemptive scheduler for the IOS operating system Received numerous awards for contribution to security, high availability and kernel infrastructure work, including "Individual Achievement award" ## Education ### Bachelor's degree in Computer Science and Engineering Ramaiah Institute Of Technology ## Contact & Social - LinkedIn: https://linkedin.com/in/sudhakardatta --- Source: https://flows.cv/sudhakar JSON Resume: https://flows.cv/sudhakar/resume.json Last updated: 2026-04-05
