Backend engineer specializing in distributed systems, fault-tolerant services and optimizations.
IndiaWhat I'm looking for
I am a backend software engineer focused on building resilient, scalable distributed systems and improving operational efficiency. I have hands-on experience in event-driven architectures, microservices, and observability.
At Celigo I implemented auto-recovery for rate-limit errors, led decoupling of Salesforce microservices, and contributed to multi-environment support, AWS SDK upgrades, and legacy code deprecation efforts. I drive infra optimizations that reduced CPU by 25% and memory by 20% through profiling, load testing and memory-leak detection.
I configure observability stacks (New Relic, Splunk, PagerDuty), set up autoscaling with KEDA, and own monitoring to mitigate memory spikes and pod restarts. I have implemented WebSocket-based services handling thousands of concurrent connections per second and worked with Kafka, Redis, MongoDB, Docker and Kubernetes.
I mentor new engineers, served as Scrum Master, build productivity tooling (sprint closure & burndown analysis using Jira + LLM API wrappers), and actively solve competitive programming problems. I pursue practical ML/AI integrations such as a GenAI personal agent and have prior internship experience at Zomato.
