What I'm looking for

I seek backend/cloud roles where I can build scalable systems, improve reliability, mentor teams, and apply AI tooling to deliver measurable business impact.

I am a senior backend engineer with a strong focus on scalable systems, cloud infrastructure, and AI-driven products. I have delivered measurable performance and cost improvements across high-traffic consumer and B2B platforms.

At Tote Technologies I engineered a Shift Management Module that cut scheduling conflicts by 40% and improved allocation speed by 30%, and implemented a Charity Checkout Flow with real-time donation tracking. Previously, I co-led backend architecture for a B2B landscaping SaaS, reducing manual proposal creation time by ~25% and integrating third-party APIs to optimize latency.

I improved performance and reliability at HealthifyMe by implementing Redis cache strategies, MySQL partitioning (4x faster reads), a caching layer to lower AWS costs by ~15%, and refactored a CDP service to Go to raise test coverage from 0% to 40%. I also built CI/CD pipelines and managed HIPAA-compliant deployments earlier in my career.

I contribute to AI system design projects and product vision, designing agentic workflows and LLM-powered feedback loops for scalable, real-time user experiences. I mentor engineers, champion testing and automation, and focus on delivering pragmatic, business-aligned technical solutions.
