Freelance Software Engineer
Current
Hisab · Freelance  —  Remote · May 2025 – Present
Project: Hisab OS — Distributed Enterprise Resource Planning (ERP)
▹ Engineered a centralized distributed OS to synchronize multi-channel operational data, reducing system data discrepancies by 95%.
▹ Designed a Zanzibar-inspired permissions engine using recursive graph traversal, enabling secure multi-tenant access for complex organizational hierarchies.
▹ Implemented a high-throughput event stream using Kafka and Redis, achieving sub-100ms synchronization between edge terminals and cloud data portals.
▹ Integrated Inngest AgentKit for predictive operational analysis, automating 30% of resource re-allocation and reducing manual audit overhead by 40%.
▹ Developed an internal AI assistant using RAG (Vector Embeddings), decreasing internal query response times for technical specifications and policies by 60%.
▹ Architected a Turborepo monorepo containerized with Docker, deployed on AWS with real-time performance monitoring via OpenTelemetry — achieving 99.9% system uptime.
