About Arijit Sil

Hello! I’m Arijit Sil, a Staff-level Software Engineer with over 12 years of experience designing and scaling distributed systems, real-time data pipelines, and AI infrastructure.I specialize in building high-throughput, fault-tolerant microservice platforms and resilient messaging frameworks that power enterprise workloads with 99.99 % reliability. My focus lies at the intersection of system scalability, data consistency, and platform reliability—turning complex distributed architectures into predictable, self-healing systems.My expertise spans distributed messaging (Kafka, SQS), data-lake ingestion pipelines (Spark → Iceberg), low-latency caching and coordination (Redis), and AI infrastructure for model orchestration and guardrails. I’m passionate about solving scale, resilience, and efficiency challenges in fast-growing, mission-critical environments.Currently, I’m researching XOR based fingerprinting and probabilistic algorithms for large-scale data reconciliation—exploring how mathematical fingerprints and sketching techniques can detect drift, incompleteness, and silent data corruption without scanning entire datasets.Highlights & Impact:• Architected multi-tenant distributed platforms processing 10 M + events/day with 99.99 % uptime.• Designed a distributed messaging library (AWS SQS-based) with partition-aware backpressure, dynamic retries, and failure isolation—adopted by 20 + services within 1 month.• Built Kafka → Spark → Iceberg ingestion pipelines (5 GB +/ day) optimizing partitioning and parallelism to cut query latency by 20 %.• Developed AI guardrail and orchestration services delivering policy compliance with < 20 ms latency overhead, now used across multiple product teams.• Recipient of multiple awards for Engineering Excellence and Enterprise-wide Innovation in distributed-platform design.
