S. Borjas - Resume | Full Stack Developer & Blockchain Inventor

Professional Summary

Full Stack Developer and inventor with 1.7M+ lines of production code, a 58-claim patent filing, and 5 years of experience building mobile apps, blockchain infrastructure, and AI systems. Pioneered pay-per-visit advertising with stablecoins on blockchain — the first system to pay users USDC on-chain upon cryptographically verified physical presence at a business, with Solidity smart contract escrow and 5-sensor fusion proof. Built the GASI (Geo-Ad Spatial Intelligence) platform with dark-zone causal attribution, on-chain escrow settlement for fitness competitions, cross-chain CCTP bridging, and a voice AI agent executing 65+ blockchain operations via natural language. Google Cloud Partner. Jason Calacanis Incubator graduate. Circle and Coinbase early access pioneer with contracts deployed on Base and ARC testnets. Incorporated in both Delaware (Lucilla, Inc.) and Canada (16699448 Canada Corp).

Experience

Founder & Lead Developer @ Lucilla Technologies

2024 - Present

Solo-built 1.7M+ lines of production code. 5 Solidity contracts (1,866 lines), 96 blockchain Cloud Functions (7,730 lines), 1,155 Dart files, 203 total Cloud Functions. Dual-chain deployment (Base Sepolia + ARC). Delaware + Canada incorporated. 58-claim patent filed.

Blockchain & Smart Contracts

Wrote 5 upgradeable Solidity contracts (UUPS proxy, AccessControl, ReentrancyGuard): GasiRewardPool, LucillaPaymentsV1, CreatorMonetizationV2, SocialRoomsV1, AgentRegistryV1 — all deployed on Base and ARC testnets
Engineered on-chain USDC escrow for fitness competitions — full match lifecycle (create, join, settle, refund) with configurable fee tiers, atomic multi-winner payouts, and anti-replay protection
Built advertiser-funded reward pool contract — smart contract escrow that autonomously distributes stablecoins to user wallets upon verified physical presence, powering a novel pay-per-visit advertising model
Implemented cross-chain CCTP V2 bridging (burn-and-mint) between Base and ARC, plus atomic on-chain fee splitting for creator monetization (tips, streaming, content access)

Agentic Wallet & NLP-to-Blockchain Pipeline

Built a 4,676-line agentic wallet executor — persistent floating AI agent that parses natural language commands and executes on-chain transactions: "send $5 USDC to @username" resolves username to wallet address and submits the transfer
Implemented 65+ tool functions callable from voice/text: send USDC, check balances, create matches, claim rewards, manage subscriptions, navigate app — all through NLP intent parsing with Gemini function calling
Engineered programmable spending-rule wallets — agent wallets with per-transaction limits, daily caps, and operator-approved autonomous execution without user signatures

AI / ML / Data Layer

Built Google ADK multi-agent grocery system (5,433 lines) — agentic commerce where AI agents generate personalized meal plans, build optimized shopping carts, and compare prices across stores using ML
Engineered proprietary location intelligence pipeline (14,600 lines, 33 backend modules) — real-time analytics, predictive modeling, audience segmentation, and automated campaign optimization at scale
Built patent-pending multi-sensor presence verification — fuses multiple independent device signals into a single confidence score for financial-grade physical location proof (details under NDA / patent filing)
Built BigQuery ML integration with agent learning system — behavioral prediction, engagement funnel analytics, and self-optimizing campaign performance across geographic markets
