About Joyson Dsouza
At Dream11, I lead engineering for core platforms — Auth & Identity, Communications, and API Gateway — serving 250M+ users across 6 Dream Sports portfolio companies, leading teams of 10–16 engineers across 3 products.My work spans a distributed MQTT system handling 20M+ concurrent connections (driving a multi-crore revenue uplift), a ReBAC-based IAM platform for fine-grained authorization, and a multi-tenant AI-powered customer engagement platform using RAG and vector search for real-time content personalization.I care about the details that matter at scale: latency benchmarks, fault boundaries, cost efficiency, and architectural decisions that are hard to undo. Some outcomes I\'m proud of — 35% reduction in infrastructure spend, platform uptime at 99.9%, MTTR reduced by 40%, and a datastore evaluation framework that standardized selection across YugabyteDB, CockroachDB, Spanner, and DynamoDB org-wide.Beyond individual systems, I drive architecture governance through cross-team review boards, lead reliability practices via SLO definition and structured incident reviews, and mentor engineers across distributed systems design and performance tuning.Currently exploring: real-time messaging at scale, identity & access management, and AI-driven personalization infrastructure.Skills: Distributed Systems · MQTT · Kafka · GraphQL · IAM/ReBAC · RAG · High Availability · Java · AWS · Kubernetes · Microservices
