About
SUNDEEP DAYALAN EST. 2019 — PRESENT
I build the systems that 5 million people rely on without ever noticing — which is exactly the point.
Software Development Engineer II at Amazon Web Services with 5+ years architecting fault-tolerant, high-throughput distributed systems across cloud infrastructure, fintech, and agentic AI. Expert in Python, Java, and React/TypeScript — delivering production-grade LLM infrastructure and Kafka streaming pipelines at sub-200ms p99 latency with 99.99% uptime.
Published Springer researcher and pending patent holder in smart traffic systems. Proven force multiplier: I mentor engineering squads, author Architectural Decision Records, and build the high-ownership cultures that make good systems inevitable.
Off the clock — chasing new countries, communities, and cuisines. Always planning the next trip.

TRACK RECORD
Experience
Aug 2026 — Present Amazon Web Services Redmond, WA, USA
SDE II
Building the telemetry infrastructure behind Amazon Aurora and RDS — systems that collect, ingest, and route database telemetry across millions of instances, feeding a fleet-wide data lake and AI-driven engines that detect performance anomalies, diagnose root causes, and deliver tuning recommendations to customers at massive scale.
May 2024 — Jul 2026 Accenture Contract USA
Software Engineer
Architected a production-grade banking platform end to end — Python/Java Spring Boot APIs, React/TypeScript frontend, and Kafka streaming pipelines serving 5M+ users at sub-200ms p99. Delivered 99.99% uptime with sharded Redis clusters, OpenTelemetry tracing across 15+ microservices, and Terraform/Jenkins GitOps automation, while driving zero-trust RBAC and org-wide ADRs across 4 squads.
Jun 2019 — Aug 2022 Accenture Chennai, India
Associate Software Engineer
Designed fault-tolerant REST & GraphQL APIs sustaining 5M+ TPS at sub-100ms SLAs and built PySpark ETL/ELT pipelines on Databricks with Delta Lake — cutting large-scale processing time 45% through Python and BigQuery optimization while mentoring junior engineers on SRE practices.
