ProductNow

Senior Software Engineer

Building an AI-native operating system for product & engineering teams, connecting plans, requirements, and execution into a shared intelligence layer.

Oct 2025 - Present
Built an AI-native operating system for product & engineering teams, connecting plans, requirements, and execution into a shared intelligence layer that stays current in real time.
Developed agentic "AI teammates" that plug into existing workflows to reduce coordination overhead (alignment, planning, handoffs, status updates).
Shipped end-to-end features in a TypeScript monorepo stack (Next.js/NestJS), with a strong focus on UX clarity, performance, and reliability.
Contributed to enterprise readiness: identity/SSO via Auth0, continuous security posture monitoring via Vanta, and auditability/access controls supporting SOC 2 Type II readiness.
Partnered closely with product and design to translate messy strategy into crisp workflow primitives (strategy → roadmap → sprint planning → delivery).

FoxyAI

Senior Software Engineer

Built and maintained Next.js/TypeScript dashboards for AI-powered property intelligence with multimodal search and subscription billing.

Dec 2023 - Sep 2025
Built and maintained Next.js/TypeScript dashboards to visualize AI-powered property intelligence (condition/quality scores, damage detection, renovation forecasts, and 360° valuations).
Led frontend modernization and performance optimization by upgrading from Next.js Page Router to the App Router, streamlining routing and data fetching, and significantly improving responsiveness and user experience.
Integrated a multimodal, LLM-powered advanced search using a Retrieval-Augmented Generation (RAG) system, enabling intuitive image-and-text queries across large-scale property datasets and delivering more accurate, context-aware results.
Developed full-stack data flows from image ingestion through AI inference to visual output, ensuring speed, reliability, and alignment with product goals.
Implemented a subscription and billing system using Stripe Checkout and a customer portal for plan management, invoices, and payments.
