What I've Built

Real systems solving real problems

Swift Protocol

Stripe for AI Agents

Production on Base L2

The problem: AI agents need autonomous payment infrastructure but existing systems require human intervention and can't handle micro-transactions. My solution: Production payment infrastructure enabling agents to transact sub-cent payments with cryptographic identity verification.

Key Metrics

  • 96% success rate
  • Sub-cent payments
  • 20+ TPS

Technical Highlights

  • 3 smart contracts deployed
  • Autonomous agent economy
  • 100x cost reduction

Tech Stack

Database Schema Deployer

Custom Deployment Platform

Production @ Associa

The problem: Associa was paying $140K+ annually for Octopus Deploy. My solution: Built a custom deployment platform from scratch that does the same job for ~$100/year in AWS costs.

Key Metrics

  • 99.9% cost reduction ($140K+ to ~$100/year)
  • Multi-environment support (QA/UAT/Prod)

Technical Highlights

  • Smart version management
  • Automated AWS workflows
  • Prevents duplicate deployments

Message Pusher

Event-Driven Sync System

Production @ Associa

The problem: Synchronous APIs were timing out on large datasets (1000+ records), causing manual intervention. My solution: Built an event-driven microservice that processes data asynchronously with job tracking and real-time status updates.

Key Metrics

  • 10K+ records/hour processing
  • 99.9% uptime
  • 70% less manual work

Technical Highlights

  • Strategy pattern for 6 entity types
  • Correlation IDs for tracing
  • Auto-scaling serverless architecture

Experience

Building production systems at scale

Founder / Engineer

Swift Protocol

Apr 2025 – Present

Problem

AI agents need autonomous payment infrastructure but existing systems require human intervention and can't handle sub-cent transactions

Solution

Built "Stripe for AI agents" - production payment infrastructure with cryptographic identity and streaming payments on Base L2

Impact

96% success rate, sub-cent transactions, zero human intervention

  • Achieved 96% success rate processing 50+ micro-transactions with sub-cent payments (0.000001 ETH minimum)
  • Built autonomous agent economy with zero human intervention - agents register, verify identity, and transact independently
  • Deployed 3 production smart contracts on Base L2 with 100x cost reduction vs Ethereum mainnet
  • Targeting 1,000+ TPS Stripe-level performance with current 20+ TPS throughput

Software Developer

Problem

Octopus Deploy was costing $140K+ annually while manual database deployments were error-prone across 5 environments

Solution

Built full-stack Database Schema Deployer (DSD) with Angular frontend, NestJS backend, and AWS orchestration

Impact

$140K+ saved annually, 5 environments, zero deployment errors

  • Replaced expensive third-party tool achieving 99.9% cost reduction ($140K+ to ~$100/year)
  • Built event-driven sync system processing 10K+ records/hour with 99.9% uptime, eliminating API timeouts
  • Automated DACPAC deployments across 5 environments with intelligent hosted/non-hosted database routing
  • Implemented multi-step deployment wizard with client selection, version management, and zero deployment errors
