Cover image for Built an AI concierge for

Built an AI concierge for a luxury fashion brand 🤍 Wanted to push past a basic FAQ bot, so I built "Élise" — a fully branded AI concierge for a fictional boutique fashion label, Maison Élise. 🔹 Greets visitors by name-dropping exactly what she can help with, hours, shipping, returns, styling appointments 🔹 Quick-reply buttons for the most common questions, so visitors barely have to type 🔹 Real, specific answers — not vague filler. Ask about shipping and she'll tell you the actual cost, free-shipping threshold, and same-day cutoff time 🔹 Fully on-brand: the concierge panel matches the site's warm, editorial aesthetic instead of feeling like a bolted-on support widget 🔹 Connected admin panel to track how the concierge is being used The goal wasn't "add a chatbot" — it was making the AI feel like an actual extension of the brand's in-store experience, the way a real concierge would greet you walking into a boutique. Built entirely in Base44 👇 https://elise-chat-flow.base44.app/

Cover image for I've contributed as a lead

I've contributed as a lead engineer to a multi-tenant HR SaaS platform, owning major backend architecture and full-stack feature delivery. I designed and built a workflow and approval engine supporting parallel execution, quorum-based approvals, delegation, SLA-based escalation, decision tables, and sub-workflows. I also built its visual workflow designer, template/document generation, forms, search, authorization, integrations, and observability capabilities. The platform uses TypeScript, Cloudflare Workers, Hono, PostgreSQL, Drizzle ORM, React, TanStack, Cerbos, and OpenTelemetry.

Built and maintained major parts of a production real estate technology platform covering property management, leads, referrals, tours, analytics, reporting, and third-party integrations. I owned substantial backend and frontend functionality using NestJS, PostgreSQL, Prisma, Redis, React, Redux Toolkit, AWS, and Socket.io (http://Socket.io). My work included high-volume analytics, database optimization, reporting pipelines, timezone-aware scheduling, complex forms, multi-tenant functionality, and integrations with external real estate and productivity platforms.

Built a distributed data ingestion system for collecting listing, lead, and analytics data from multiple real estate data sources. The system used Python, FastAPI, Celery, Redis, Selenium Grid, and Docker to coordinate authenticated scraping across concurrent workers. I designed shared session management using Redis locks and pub/sub, parallelized scraping workloads with Celery, and implemented missing-page reconciliation to improve reliability. The production pipeline was designed to process large ingestion workloads reliably without manual intervention.
