# Aditya D. > Staff Software Engineer | Large-Scale Distributed Systems | Cloud Platform Architecture Location: San Francisco Bay Area, United States Profile: https://flows.cv/adityad I design and evolve large-scale distributed systems that power business-critical platforms at global scale. Over the course of my career, I’ve worked across high-scale consumer ecosystems — from global content delivery networks to marketplace infrastructure and digital payments — shaping systems that must handle significant throughput, complex interdependencies, and continuous growth without compromising reliability or performance. At PayPal, I define architecture for services within a global payments platform supporting 400M+ active accounts. My work focuses on system decomposition, interface and data model design, and evolving platforms that can scale predictably while remaining adaptable. I spend much of my time navigating architectural tradeoffs — balancing latency, consistency, scalability, and operational simplicity in environments where small design decisions have large downstream impact. I’m most engaged in distributed systems problems where clarity of design, long-term maintainability, and performance at scale matter as much as immediate feature velocity. ## Work Experience ### Staff Software Engineer @ PayPal Jan 2020 – Present | San Jose, CA Define and own the long-term architectural evolution of a globally distributed control-plane platform serving 450M+ consumers and 36M+ merchants, operating at ~150K+ requests/sec with 99.99% availability across multi-region deployments. Leading a multi-year cloud modernization initiative decomposing a legacy monolithic system into independently scalable, low-latency services, introducing cell-based regional isolation and distributed decisioning; initial ramp supports ~25% of high-throughput API traffic with sub-10ms decision targets. Driving platform-wide performance optimization across critical request paths, setting technical direction and guiding teams on latency reduction, capacity efficiency, and SLO-safe rollout strategies. Architected platform extensions enabling high-volume checkout and passwordless access flows while preserving latency and resiliency guarantees under global traffic conditions. Designed cross-platform interoperability mechanisms supporting large-scale user convergence (70M+ users) with production rollout in under four weeks. Contribute to platform-wide architectural governance through formal design reviews, ADR standards, technical hiring, and mentorship of senior engineers, strengthening distributed systems rigor across service domains. ### Software Engineer 2 @ Akamai Technologies Jan 2018 – Jan 2020 | Santa Clara Core engineer within the Media Delivery Product Engineering organization, contributing to the Cloud Embed HTTPS Orchestration platform supporting ~25K enterprise deployments across Azure and IBM Cloud. Designed and implemented distributed RESTful APIs enabling automated, ACME-based certificate lifecycle provisioning and secure custom-domain integrations for multi-cloud environments. Architected a highly available Java proxy responsible for authentication and authorization of cloud partner API traffic, ensuring secure and fault-tolerant integrations under production workloads. Contributed to decomposition of a legacy certificate provisioning monolith into microservices, increasing release frequency by 4× through CI/CD-driven automation.

Designed and developed in-house frameworks in Java and Node.js powering ~40% of static content delivery on eBay.com. ### Software Engineering Intern @ ebay Jan 2016 – Jan 2016 | San Jose California USA Developed a distributed health-check framework validating 2000+ microservices, enabling scalable reliability validation for the SRE organization. Participated in internal open-sourcing initiatives and integration with third-party tools, improving platform extensibility. Designed and implemented automated test suites (JUnit) with SonarQube-driven quality metrics to improve code coverage and reliability. Built real-time distributed processing components using Apache Storm and Couchbase. Developed an Android prototype leveraging NLU-based query handling for eBay Search; secured 2nd place at HackWeek for next-generation product innovation. ### Technical Solutions Engineer @ Akamai Technologies Jan 2013 – Jan 2015 | Bangalore Analyzed large-scale CDN traffic using internal big-data systems to improve reliability and performance across globally distributed infrastructure. Performed deep network-level diagnostics and log mining across fault-tolerant streaming production systems, identifying root causes of content delivery and performance issues. Partnered with Media Analytics Engineering on performance optimization initiatives and developed Android-based HLS playback POCs to validate streaming reliability improvements. ## Education ### Master's degree in Computer Science USC Viterbi School of Engineering ### Bachelor of Engineering (B.E.) in Computer Science and Engineering KLE Technological University - Hubballi (India) ### Pre-University Education in Physics, Chemistry, Mathematics and Statistics Karnataka University, Dharwad ### Secondary School Leaving Certificate Pavan English Medium High School , Dharwad ## Contact & Social - LinkedIn: https://linkedin.com/in/adityardesai --- Source: https://flows.cv/adityad JSON Resume: https://flows.cv/adityad/resume.json Last updated: 2026-04-12
