About me
As a full-stack developer and freelancer, I'm passionate about building digital products that enhance art and design. My journey into the world of technology and programming began with a curiosity that led me to explore different areas of knowledge. Eventually, I found my calling in creating solutions that positively impact people's lives. My focus is on designing and developing products that are not just functional, but also visually appealing. With proficiency in several programming languages like Python, HTML, CSS, and JavaScript (TS), I create customized solutions that meet my clients' specific needs while delivering an exceptional user experience. In my quest to push the boundaries of what's possible, I've expanded my knowledge base to include cutting-edge technologies like AI prompting and Solidity. This allows me to create innovative and useful solutions in the fields of artificial intelligence and cryptocurrencies. But my approach is not just about technology. As a natural leader, I enjoy working with teams and fostering open and effective communication to ensure the timely delivery of quality projects. When I'm not coding, I love immersing myself in music and art, which fuels my creativity and inspires me to think outside the box. My ultimate goal is to create exceptional digital products that not only meet my clients' expectations but also provide a unique experience for end-users. And with every new project, I aim to challenge myself and push the limits of what's possible in the world of technology and design.

AURA PAYMENTS
Aura will be a TypeScript SDK that brings production-ready escrow, multi-party splits, and USDC settlements to any application. Built with Circle Developer-Controlled Wallets and Arc blockchain, Aura transforms complex payment workflows into simple API calls. Integration time: 4 hours. 🔴 Split payment accounting requires custom ledger logic and endless reconciliation 🔴 Escrow services take 3-6 months to build and $100K+ to secure properly 🔴 Multi-party settlements create operational overhead and delayed payouts 🔴 Dispute resolution needs legal frameworks, trust infrastructure, and manual arbitration 🔴 Audit compliance demands immutable records and banker's precision Our Solution: Aura Payments SDK Aura is a production-ready TypeScript SDK that enables developers to build Stripe Connect-level payment infrastructure in hours instead of months—with blockchain transparency, Circle's enterprise security, and zero counterparty risk. What We've Built (Phase 3 Complete - Production Ready): ✨ Drop-in Escrow Engine Create secure escrow wallets in 3 lines of code Automated state machine: initiated → deployed → funded → locked → released Built-in dispute resolution with admin oversight Evidence management and audit trails Zero-trust architecture—funds locked until conditions met 💰 Multi-Party Split Payouts Define unlimited recipients with basis point precision (8500 = 85%) Automatic calculation and distribution Support for sellers, platforms, affiliates, logistics, taxes—any role Parallel transfer execution with retry logic Banker's rounding for perfect reconciliation 🏦 Circle Wallet Orchestration Developer-controlled wallets (no user key management) Lazy wallet creation for buyers, sellers, platforms Native USDC transfers with sub-second confirmation Gas-abstracted UX—users never see blockchain complexity Enterprise-grade key security by Circle ⛓️ Blockchain-Ready Architecture
