What I'm looking for

I'm looking to build scalable, reliable backend and serverless products, contribute to AI-powered applications, and work on clean architecture, performance, and maintainable systems.

I've built scalable, fault-tolerant backend services at Innov7Lab using Node.js, Express.js, TypeScript, and AWS. I designed serverless, event-driven systems with Lambda, API Gateway, SQS, EventBridge, DynamoDB, and S3 for high availability and elastic scale.

I've integrated LLMs and agentic workflows into production products, modeled MongoDB schemas for core business processes, and reduced latency through stronger API patterns, system design, and data structures. I work independently with unit testing and TDD to deliver maintainable systems.

Previously at Cloudzies, I led the architectural design of an edtech product on AWS serverless infrastructure. I also built SnapDB, a high-performance JSON database for Node.js, and delivered AI-powered marketing automation across WhatsApp, email, and SMS.
