Aman Garg

Backend Software Engineer with 3+ years of experience building production systems using Java and Spring Boot. Experienced in designing and owning backend services, REST APIs, distributed data-processing workflows, and cloud integrations across AWS, Azure, and GCP.

Software Engineer at Intellicus Technologies (2025-01 – Present)

• Built core pieces of a natural language OLAP querying feature, including intent classification, LLM orchestration, and SQL/MDX query generation, cutting average query turnaround time by roughly 50%.
• Added a query-processing layer that lets the platform run SQL directly against unstructured PDF content, removing a manual data-extraction step that used to slow down onboarding new PDF-based data sources.
• Built and maintained backend integrations with AWS S3, Azure ADLS, and Google Cloud Storage, handling cloud-specific auth, credentials, and tenant-level data isolation across customer environments.
• Designed a scheduled Spring Boot cleanup service that finds and removes stale data across HDFS, relational databases, Redis, and local storage, with failure handling so partial cleanups don't leave the system in a bad state.
• Debugged and fixed production issues across Hadoop, Spark, AWS, Azure, GCP, Snowflake, BigQuery, and PostgreSQL integrations, doing root-cause analysis and coordinating fixes across environments.
• Fixed a recurring class of reliability issues in distributed data-processing workflows tied to resource management, session lifecycle, and cross-cloud auth, which came up repeatedly during customer deployments.

Software Engineer (E1) at Crest Data Systems (2023-11 – 2024-12)

• Built a Java-based log-processing pipeline handling 280M+ events per day, using multithreading, batching, schema validation, and failure recovery to keep throughput stable under load.
• Owned the backend services that ingest, process, schedule, and export large volumes of security log data, including retry and recovery logic for failed processing tasks.
• Reduced data loss by around 40% by tracking down failure scenarios in the log-processing workflows and building automated recovery for them instead of relying on manual restarts.
• Built Vue.js dashboards and the REST APIs behind them so the team could monitor processing status, system health, and failures without digging through logs.
