Applied AI
Engineer

I design and ship LLM-powered systems, document intelligence pipelines, and real-time AI workflows — turning ambiguous, high-friction problems into production software that scales.

Building at the frontier

Currently Software Engineer at Randomwalk AI — designing LLM backends for document intelligence, async job orchestration and enterprise automation.

01 — About & Experience

I build AI systems that actually work in production.

My work sits at the intersection of LLMs, backend engineering and pragmatic system design. I care deeply about latency, reliability and cost — and about making AI systems feel less like research experiments and more like infrastructure you can rely on.

Previously I built frontend experiences at docu3C, competed in national hackathons, and earned an NVIDIA Deep Learning Institute certification in AI & Accelerated Computing.

    Software Engineer

    Randomwalk AI

    Designing and deploying LLM-powered document processing systems for financial data — bank statements, transactions, reconciliation. Built async bulk-job pipelines, AI-driven nudging systems, and optimized workflows for cost, latency and reliability (retry, fallback, guardrails).

  2. Jan — Jun 2024

    Developer Intern

    Randomwalk AI

    Built backend microservices and REST APIs powering early AI applications. Automated internal workflows and shipped production features in tight agile cycles — the runway into a full-time role.

  3. 2022 — 2023

    Frontend UI/UX Developer

    docu3C

    Developed responsive React interfaces and collaborated with design to raise usability and accessibility — where the obsession with polish and detail started.
