Work Experience

Sole engineer on ClawbackAI — a production SaaS platform I architected and shipped from scratch for Hummus Republic. The platform is actively used by 40 franchise locations and 100+ franchisees, replacing disconnected spreadsheets and email chains with a unified, real-time operations hub.

The Problem

Franchise leadership had zero visibility into per-unit financial performance or compliance status. P&L data lived in disconnected spreadsheets, SOPs were emailed PDFs, and billing reconciliation was done manually — causing missed clawbacks worth thousands of dollars per quarter.

The Solution

Architected a multi-tenant React + Firebase platform with 4-tier RBAC, a Google BigQuery analytics layer aggregating financials across all franchise units, and an AI billing reconciliation engine that automatically surfaces clawback discrepancies.

Key Accomplishments

  • 4-tier RBAC system — corp admin, franchise owner, location manager, and employee access levels
  • Google BigQuery pipeline aggregating P&L, COGS, and ops data across all franchise locations in real time
  • AI billing reconciliation — auto-detects clawback gaps that previously required hours of manual review
  • Document management with versioned SOP knowledge base — reduced franchise support requests significantly
  • Construction tracker — manages bid submissions, stage budgets, and contractor dashboards for new locations
  • Real estate acquisition pipeline for new franchise location prospecting and deal tracking
  • Firebase Cloud Functions powering automated report generation, compliance alerts, and scheduled syncs
  • Sole engineer: designed schema, built all features, deployed, and maintain in production

Visit Live Site

Founded and built BriefRoom — a live AI interview prep platform serving job seekers across 440+ companies and 6 interview formats. Designed, engineered, and shipped the entire product solo, from database schema to Stripe billing to AI prompt architecture.

The Problem

Generic interview prep tools don't simulate real company formats or give meaningful feedback. A candidate prepping for Google system design needs a fundamentally different experience than one prepping for McKinsey case interviews — no existing tool provided that specificity.

The Solution

Built a multi-model AI system with company-specific interviewer personas calibrated to real hiring patterns at 440+ companies. Each session delivers STAR-scored feedback, cites the candidate's exact words, and tracks improvement across sessions.

Key Accomplishments

  • 440+ company-specific AI interviewers — behavioral, coding, system design, case, medical, and law formats
  • 4.8★ aggregate rating across 50+ verified user reviews on the live platform
  • Multi-model AI architecture — different models optimized per interview type for response quality
  • STAR scoring engine — AI quotes exact candidate answers with structured improvement feedback
  • 4-tier Stripe billing: Free → $9/wk → $19/mo → $49 Career Launch — full subscription lifecycle
  • Session history and improvement analytics — users track score trajectory across practice rounds
  • Built and shipped solo: architecture, AI prompting, billing, auth, and deployment

Embedded Systems

Wi-Fi Signal Meter

Hardware

ESP32-based device that scans nearby Wi-Fi networks and visualizes signal strength in real time using an RGB LED bar and LCD display. Signal bands mapped to color gradients for intuitive UX without a phone app.

  • ESP32 firmware scanning RSSI values across all visible SSIDs
  • RGB LED array with PWM-driven color gradients (green → red) per signal band
  • 16×2 LCD display with dynamic scrolling network list and RSSI readout

Smart Lighting System

LumenOS

Hardware

Intelligent ambient lighting system that automatically adjusts color temperature and brightness based on occupancy, ambient light, and temperature. IR remote control, multi-zone support, and a web dashboard for manual override.

  • PIR motion sensor + LDR photoresistor fusion for adaptive auto-on/off
  • DHT11 temperature sensor adjusts warm/cool bias for circadian rhythm support
  • IR remote with 20+ programmable presets; all state persisted in EEPROM
