RecruiterAI — A Fully Synced Recruiting Platform (iOS + Web) RecruiterAI helps recruiters move fast and stay organized. Capture notes, ideas, and candidate signals on the iOS app, then manage pipelines, interviews, tasks, and reports on the web — fully synced so nothing gets lost between devices. At the core is the AI Hub, featuring a job description optimizer, resume analyzer, candidate matcher, interview question generator, outreach writer, salary insights, onboarding plan generator, and AI scheduler. Powering it all is Tally AI, an expert recruiting copilot with full access to platform data. Tally AI provides context-aware insights, drafts content, and guides decisions — amplifying recruiters’ impact while keeping them in control.

RailRadar is a real-time train detection and arrival prediction system built for communities impacted by rail crossings. Using a distributed network of camera-based tripwire sensors, RailRadar detects train movements at the edge and generates bias-corrected ETAs that adapt to real-world conditions. The system delivers timely, reliable alerts without relying on railroad-provided data or centralized tracking feeds. RailRadar is designed for resilience and accuracy in the field. The platform supports community alerts, operational monitoring, and future integrations with municipal and transportation systems. This project includes full-stack system design, edge sensing logic, backend services, alerting infrastructure, and deployment workflows focused on real-world reliability, not demos.

AI Builder + Agent Studio is a system for designing, testing, and deploying AI agents and autonomous workflows as structured, production-ready graphs, not fragile prompts. At the core is Agent Studio, where workflows are defined as explicit graphs made up of agents, tools, conditionals, loops, routers, and outputs. The AI Builder sits on top of this system and generates complete workflows automatically. Instead of writing code or wiring nodes manually, users describe the goal—and the AI Builder constructs a valid workflow graph. Every workflow can be tested using a test harness, ensuring agents execute correctly before deployment. This project demonstrates how AI agents can be treated like real software systems—versioned, validated, and orchestrated—instead of one-off prompt chains.

Numun.io (http://Numun.io) is an autonomous agent and workflow execution platform designed to turn intent into action—reliably, securely, and at scale. Numun enables users and teams to design, deploy, and run AI-powered agents and workflows that browse the web, call tools, orchestrate systems, and complete real tasks end to end. At its core is a contract-based execution model that emphasizes determinism, observability, and accountability—bringing production-grade discipline to AI agents. Numun is built for developers, operators, and founders who need agents that actually work in the real world—not demos that break under pressure. This project includes full-stack platform development, execution infrastructure, agent runtime design, workflow orchestration, and system-level reliability engineering.

PetCard v2 – All your pet’s records in one app PetCard keeps your pet’s key health info—vaccinations, prescriptions, weight logs, and documents—in one simple mobile app so traveling or moving with your pet is less stressful. Version 2 focuses on cleaner navigation, faster logging, and a clearer overview of each pet’s health card, built entirely with Anything. I shipped v1 for the first hackathon, learned from that build, and iterated. The new PetCard v2 build has been submitted to the Apple Store and is currently under review. Links to: TestFlight (https://testflight.apple.com/v1/app/6755447850?build=189713954) and Anything (https://petcard.created.app)

The problem it solves Every freelance designer knows the feeling — someone fills out your intake form, and suddenly you're the bottleneck. Writing follow-ups, sending confirmations, drafting reminders, chasing proposals. The work before the work. I built the Client Intake Agent to handle all of it. What it does A 9-step automated pipeline that runs from the moment a lead submits an inquiry to the moment they receive a proposal — with the right things automated and the right things kept as drafts for human review. → New intake submission → agent drafts a branded Gmail follow-up with portfolio examples matched to the client's service request → Lead books a call → confirmation email auto-sends instantly → Day before the meeting → reminder auto-sends at 7am → After the call → agent drafts the proposal, contract, and deposit invoice when you're ready Why it's reusable The agent is built as a template — not tied to one person's data. Anyone can duplicate it, swap in their booking link, populate their portfolio database, and run the same workflow in under an hour. The instructions include a full constants block, defined status values, and copy-paste prompts to get started immediately. Judging criteria — how this entry maps — Clarity of use case: Freelance designer, client intake, first inquiry to signed proposal — Quality of instructions: Step-by-step pipeline, named triggers, send rules, guardrails, status definitions, and fallback logic — Reliability and safety: Human review on every client-facing email except confirmations and reminders — where timing matters and content never changes — Impact: Eliminates the highest-friction part of freelance ops — the first 72 hours after a lead reaches out — Craft: Branded emails, STAR-format portfolio database, placeholder links for DocuSign and QuickBooks, and a clean setup guide anyone can follow Links — Custom Agent: https://www.notion.so/agent/3352d5cd-4ef4-80a1-a3d6-009263fd916f (https://www.notion.so/agent/3352d5cd-4ef4-80a1-a3d6-009263fd916f)— Marketplace listing: https://www.notion.so/marketplace/custom-agents/client-intake-agent (in review)

This project turns my dog of 15 years into the face of an occasion-based apparel brand. The video moves through a series of storefront-style window displays, revealing new looks for weddings, holidays, and celebrations. Inspired by his loyalty and personality, the concept presents dog apparel as a polished brand story, not just costume wear.

Excited to share what I built for the Figma Makeathon Reelwish (https://<https://reelwish.figma.site/app>) lets you record a 15-second video wish with real-time face-tracked props and gesture reactions baked right into the video. What I built in Figma Make: → Real-time face tracking using TensorFlow BlazeFace — props follow your face on camera → Hand gesture detection — thumbs up triggers confetti, peace sign triggers hearts, OK sign triggers fireworks → Teleprompter with scripts by occasion and vibe — Hype, Heartfelt, or Funny → Full video recording and sharing pipeline → Beautiful receive page for the person you're celebrating Link to the project: https://reelwish.figma.site/app Built for the #FigmaMakeathon — incredibly proud of how far this came in 48 hours.
