What I'm looking for

I’m a Senior Software Engineer with 8+ years of experience building scalable products using Node.js, Python, React, AWS, Kafka, Microservices, and AI/LLM technologies. I’d be excited to contribute to your team and product.

I'm building cloud-native aviation operations platforms for Etihad Airways through IDC Technologies, covering flight scheduling, operational control, and airline workflows. I design Node.js, NestJS, TypeScript, and Python/FastAPI microservices with Kafka-driven processing and Redis caching.

Previously at Biz2X/Biz2Credit, I built backend services for lending workflows including origination, underwriting, repayment, lender management, reporting, and customer lifecycle operations. I improved PostgreSQL workloads and used Redis and asynchronous processing to support compliance-oriented financial systems.

I've delivered government digital-transformation platforms at NISG and multi-tenant SaaS, chatbot, and workflow-automation products at Credencys Solutions. My work spans secure REST and SOAP integrations, API security, cloud modernization, payments, inventory, data synchronization, and enterprise automation.

I build production-ready systems across AWS and Azure using Docker, Kubernetes, Terraform, and CI/CD. I'm also focused on AI/LLM applications, RAG, vector search, AI agents, tool calling, and enterprise-ready agentic workflows.
