I'm Bibek Das, a Full Stack & Backend Engineer. I specialize in scaling mission-critical microservices, multi-server data pipelines, Kafka event backbones, and zero-downtime PostgreSQL workloads on AWS and GCP.
Full Stack Engineer @ CredResolve
Recruiters often ask how the 585K batch ingestion and notice generator works. Explore the interactive pipeline simulation below to see the microservices, Kafka event streams, Redis cache, and write-optimized PostgreSQL flow in action.
Custom @NormalizeInput annotation validates and sanitizes external vendor payloads.
Partitioned topic streaming handles asynchronous dispatch to prevent microservice bottleneck under peak load.
Redis cache clusters eliminate redundant lookups; multi-threaded Spring workers assemble legal templates dynamically.
Chunked batch inserts, unlogged staging tables, and indexed partitioning ingest 585K records in 3.5 minutes cleanly.
Proven enterprise engineering since 2024
Spearheaded and engineered the high-throughput legal notice generation system handling multi-format output at scale.
Designed and launched high-value product workflow enhancements directly increasing business transaction throughput.
Overhauled database ingestion across a multi-server, single PostgreSQL cluster using unlogged staging and batch execution.
@NormalizeInput annotation to standardize, sanitize, and validate incoming requests before hitting business logic.
