๐Ÿ‘‹ Hi, I'm Chetan Dongare

Backend Software Engineer | Specialist in Java, Spring Boot, & Distributed Architectures

I design, build, and optimize high-throughput, secure backend systems and microservices. My engineering focus centers on enterprise security migrations, distributed caching patterns, and centralized data pipelines.


๐Ÿš€ Core Engineering Highlights

  • Enterprise Security Migration: Accelerated microservice auth lookup latency by 32% by deploying an OAuth2 PKCE framework backed by Redis session caching layers.
  • Distributed System Topologies: Engineered a fault-tolerant URL shortener utilizing Base-62 encoding and Snowflake-based ID generation, maintaining stable sub-50ms redirection latencies.
  • System Observability & Monitoring: Centralized production logging architectures using Spring Boot AOP, reducing MTTR via structured SLF4J tracing and automated Grafana anomaly-alert pipelines.

๐Ÿ’ป Featured Production-Grade Architectures

  • Problem Space: High-throughput identifier generation and low-latency cache redirection.
  • Implementation: Built an automated scaling backend using Snowflake ID generation to systematically eliminate unique ID collisions across concurrent node clusters.
  • Impact: Implemented a Redis look-aside caching profile that cut database read metrics by 41%, delivering reliable sub-50ms responses under heavy traffic.
  • Problem Space: Highly concurrent multi-user state synchronization and document conflict mitigation.
  • Implementation: Leveraged full-duplex WebSockets backed by the STOMP protocol to coordinate fast state transitions across active client frontends.
  • Impact: Integrated a native Operational Transformation (OT) layer to programmatically resolve simultaneous document text mutations, boosting sync reliability by 32%.

๐Ÿ† Recognitions & Credentials

  • National Finalist โ€“ Google Hack4Change Hackathon (Aug 2024) | Selected for top tier impact and scalable architecture design.
  • Academic Foundation โ€“ B.E. in Computer Engineering from Thapar Institute of Engineering and Technology (2021 โ€“ 2025).
