About Me

As a Senior Software Engineer at Alterest, I specialize in building scalable web and AI-driven systems across frontend and backend stacks. I architect production platforms using React, TypeScript, and FastAPI, with a focus on designing deterministic, reliable systems that translate complex problems into high-impact, user-facing solutions.

In my current role, I've architected a Hybrid Loop multi-agent system (8 agents) using Google ADK that cut average response times from 12s to 4s, and shipped a natural-language-to-SQL pipeline with RAG-powered Vega-Lite generation achieving 95%+ chart accuracy. I've also reduced perceived wait times by 3x through Server-Sent Events streaming with live agent progress tracking.

Previously at HashedIn By Deloitte, I led development of enterprise licensing dashboards that reduced manual overhead by 40%, improved Lighthouse scores from 75 to 92, and increased test coverage from 20% to 80% using Jest and React Testing Library. I also automated Okta app provisioning workflows, reducing setup time by 70%.

My approach combines technical depth with a results-oriented mindset, always focusing on solutions that deliver real, quantifiable outcomes for users and stakeholders.
