Our clients praise us for our great results
"InexpensiveCoders architected our high-frequency ledger processing 18,000+ TPS with zero downtime."
InexpensiveCoders delivered an immutable double-entry core banking engine on Go and Kafka. Their squad integrated ISO 20022 compliance seamlessly and reduced our API latency by 65%. I 100% recommend them for any mission-critical financial system.
Rajesh Sharma
VP of Engineering, FinTech Solutions (Bengaluru, Karnataka)
"Transformed our multi-brand kitchen operations into an automated AI routing powerhouse."
We were struggling with KDS order syncing and driver dispatch bottlenecks across 45 locations. The InexpensiveCoders team deployed an automated kitchen display system with real-time web sockets and sub-second route optimization that boosted order fulfillment speed by 40%.
Priya Sundaram
CTO, CloudKitchens India (Mumbai, Maharashtra)
"Their Agentic RAG and Vector DB architecture unlocked instant document retrieval for our 500k assets."
The RAG pipeline engineered by InexpensiveCoders handles complex real estate legal contracts with Milvus and hybrid reranking. Query response dropped from 8 seconds to under 300ms with incredible accuracy. An elite team of AI architects.
Ankit Verma
Head of AI Infrastructure, PropTech Labs (Gurugram, Haryana)
"Flawless multi-region AWS EKS Migration with zero packet loss and 45% infrastructure cost reduction."
InexpensiveCoders migrated our legacy Kubernetes clusters to ARM-based Graviton4 instances using Terraform and GitOps. The transition had zero customer impact, rock-solid security compliance, and drastically reduced our monthly AWS cloud spend.
