Projects

Full-Stack AI Product - AI-Powered Car Rental Platform

Technologies: Next.js 16, React 19, TypeScript, Supabase, PostgreSQL, Google Gemini, Tailwind v4

View case study
  • Single-Codebase Full-Stack Architecture: Built a customer storefront and staff dashboard in one Next.js 16 App Router codebase, using server components and server actions for all data access with no client-side fetching library.
  • Grounded AI Recommendation Pipeline: Designed a recommendation pipeline where Gemini interprets free-text trip requests and ranks results, while Postgres supplies every candidate and a deterministic scorer computes match percentages — making hallucinated cars or prices structurally impossible.
  • Automatic Lead Qualification: Implemented lead qualification that scores and prioritizes inbound inquiries, with model output grounded against database records so priority and missing-information fields are recomputed rather than trusted.
  • Database-Enforced Domain Model: Modeled the domain in Postgres with 37 migrations, row-level security, SQL views and RPCs, preventing double bookings via a date-overlap exclusion constraint enforced at the database layer.
  • End-to-End Notification Workflow: Built an inquiry → background qualification → Zapier → authenticated webhook → Resend email flow with bearer-token constant-time verification, rate limiting, and typed error classification with retry on transient upstream failures.
  • Analytics Dashboard: Developed a responsive dashboard with Recharts analytics, a d3-geo sales map, and URL-driven filtering, sorting and pagination shared across list pages; tables switch to card layouts on smaller viewports.

EMR Platform - MySpaLive

Technologies: React, JavaScript, Supabase, PostgreSQL, REST APIs, Stripe, QUO

View case study
  • Patient Booking & Communication: Built appointment scheduling flows supporting 100+ weekly bookings while preventing overlap errors, and integrated QUO calling to support remote consultations and smoother patient communication.
  • Payment Processing: Integrated Stripe billing flows for subscription handling across the platform, making payment collection more reliable while fitting into the larger EMR workflow.
  • Bulk Data Import & Mapping: Designed a bulk import tool that mapped 1,000+ rows with high accuracy, cutting manual onboarding work by 40% and making account setup more scalable for operations teams.
  • Provider Onboarding Systems: Architected onboarding workflows that automatically triggered downstream registrations and referral-related steps, reducing administrative coordination during provider setup.
  • Complex UI & Role-Based Logic: Implemented dynamic forms, validation-heavy user flows, and role-based access patterns to support multi-tenant usage without compromising usability.

Engineering Control Tower - CollabAI

Technologies: React, Supabase, PostgreSQL, GitHub API, AI Agents, REST APIs, Slack

View case study
  • GitHub Analytics: Architected GitHub activity tracking and reporting to monitor developer output across daily, weekly, and monthly views, giving teams better visibility into engineering activity.
  • Automated QA Pipelines: Built PR review and QA tracking workflows across 600+ repositories, saving project managers around 5 hours each week that would otherwise be spent on manual follow-up.
  • Workflow Automation: Implemented task assignment flows that triggered when bugs or delivery bottlenecks were identified during PR review, helping move issues into action faster.
  • Multi-Channel Notifications: Integrated Slack and email notification paths to keep stakeholders updated in real time on QA status, review findings, and assigned next steps.
  • Knowledge Base Integration: Connected code quality and reporting signals into a central knowledge layer so project information became easier to search, understand, and act on.
