Software Engineer·Founder mindset in 0→1 environments—owning problems end-to-end and turning ideas into reliable products.

Summary

Wanderer at heart · builder by trade

I'm a curious wanderer at heart and a builder by trade—a software engineer who lives for road trips, bold ideas, and end-to-end systems that move the needle. Whether I'm shaping architecture across platforms or rolling up my sleeves on a gnarly bug, I bring real ownership, a creative streak, and a bias for action. I thrive where curiosity meets craft, and where the bar for reliability and user experience stays high.

My journey so far has been a patchwork of hands-on wins—shipping features, closing the loop on issues, and helping shape dependable products where purpose and human-centered design go hand in hand. Outside the code, I'm drawn to social causes and community work, because technology at its best doesn't just connect systems—it brings people together and leaves room for impact beyond the roadmap.

Experience

Roles where I shipped full-stack systems, AI products, and resilient backends.

  1. Founding Software Engineer

    Todaiyo.ai · MA, United States

    Sep 2025 – Present

    • Owned and scaled backend systems end-to-end, from architecture and API design through deployment and monitoring, while collaborating closely on UI/UX flows for fast, intuitive experiences.
    • Built asynchronous, event-driven workflows with queues and workers for concurrent AI-powered requests and real-time user interactions under production traffic.
    • Designed resilient backend services with reliability and uptime as core goals; proactively debugged, triaged, and resolved production incidents.
    • Led full-stack development of a production SaaS product using React, Node.js, and Supabase—integrating AI APIs, reducing OpenAI costs by 25%, implementing image-generation pipelines, and instrumenting analytics with Google Analytics and Google Tag Manager.

  2. AI Full Stack Engineer (Part-time)

    Consumer Genie · Delaware, United States

    Sep 2025 – Present

    • Architected an agentic AI-powered shopping platform that reduced cross-site product research time by 40%, using LangGraph for multi-agent reasoning (search, summarization, ranking, comparison).
    • Designed distributed, event-driven orchestration with asynchronous tasks to coordinate autonomous AI agents for scalable, fault-tolerant multi-step queries.
    • Implemented semantic search with vector embeddings and MongoDB-backed indexes; integrated DuckDuckGo, Serper, and Tavily for discovery, reviews, and recommendations.
    • Building real-time, low-latency AI pipelines on AWS with Docker and CI/CD, LLM guardrails, and cost controls for concurrency under load.

  3. Full Stack Software Engineer

    IEJL · California, United States

    Jul 2025 – Oct 2025

    • Engineered full-stack apps and internal tools with Next.js, TypeScript, and Tailwind CSS—improving UI load times by ~30% and delivering scalable APIs with real-time updates and Supabase-backed PostgreSQL sync (~25% better sync efficiency).
    • Optimized PostgreSQL schemas, indexes, and queries (Supabase) for performance and reliability under high throughput.
    • Partnered with PMs, designers, and cross-functional teams in Agile sprints—accelerating delivery and reducing iteration cycles by ~35%.
    • Deployed containerized services on AWS with Docker and CI/CD—faster, safer releases with ~40% faster deployments and ~30% better reliability.

  4. Web Development Intern

    Coincent Technologies · India

    Sep 2022 – Nov 2022

    • Built a Job Portal Management System with optimized MySQL queries and modular front-end components—cutting job posting and record processing time by ~30%.
    • Validated mobile-first flows and cross-browser compatibility; supported Java (Spring Boot) APIs and monitoring—stronger accessibility (~95% of users) and ~20% lower bounce rates.
    • Maintained ~99% uptime through automated error monitoring and rapid resolution during high traffic.
