About

Founding Engineer with 8+ years building mission-critical fintech infrastructure from the ground up — from first commit to $10B+ in total payment volume. Specializing in taking complex 0→1 products to scale. Currently architecting and scaling the engineering backbone at Juno, spanning core banking, crypto infrastructure, and AI-driven product development. 🚀 Scale & Architecture: Engineered omnichannel systems processing $10B+ TPV. Built JIT payment rails handling 100+ TPS while synchronously executing a multi-layered fraud engine (evaluating fast-in/fast-out velocity, PPD funding origins, and MCC limits). Maintained a strict sub-200ms p99 SLA by architecting a Redis-first data layer, and subsequently scaled compute throughput by migrating the core decisioning engine from Node.js to Golang (GoFiber). 🛡️ Security: Architected identity and fraud engines (Sardine, Onfido, Plaid, VGS) with biometric facial matching and field-level PII encryption (CSFLE), reducing fraud by 90% across 50k+ monthly verifications. 🤖 AI Innovation: Built multi-agent AI systems with RAG pipelines, Neo4j knowledge graphs, and vector search. Engineered autonomous AI agents (Claude, Gemini, Grok) via LangChain with cascading multi-model video generation (Grok Imagine, Seedance, PixVerse) on fal.ai — driving real-time social engagement and automated content at scale. Stack: Node.js · Golang · Python · Solana · AWS Redshift · MongoDB · Redis · Neo4j · Docker · Zero Hash · Meteora · LangChain · Plaid Open to connecting with fellow builders in fintech, DeFi, and AI infrastructure.

Core contributor to infrastructure processing $10B+ in total payment volume across crypto and fiat rails.
Decentralized Launchpad on Solana:
▸ Architected a memecoin launchpad on Solana with automated bonding curve fills, liquidity migration to Meteora DAMM/DBC pools, and programmable tokenomics — processing $200M+ in trading volume within 10 months of launch.
▸ Built autonomous AI agents (Claude, Gemini, Grok) via LangChain with RAG pipelines and Neo4j knowledge graphs for real-time social engagement and trend-driven content.
▸ Engineered cascading multi-model video generation (Grok Imagine → Seedance → PixVerse) on fal.ai with FFmpeg watermarking for automated branded content.
▸ Built a high-throughput Solana blockchain listener for real-time token event processing and a Rust-based vanity address generator for branded token creation.
Juno Core Platform (Fintech & Crypto):
▸ Engineered JIT payment rails handling 100+ TPS with a synchronous multi-layered fraud engine (PPD funding origins, MCC limits, fast-in/fast-out velocity) under a strict sub-200ms p99 SLA via a Redis-first data layer.
▸ Migrated the core JIT decisioning engine from Node.js to Golang (GoFiber) for scaled compute throughput.
▸ Architected end-to-end crypto settlement with Zero Hash, automating reconciliation for 10k+ daily RFQ trades using AWS Redshift.
▸ Built identity and fraud engines (Sardine, Onfido, Plaid, VGS) with biometric facial matching and field-level PII encryption (CSFLE), reducing fraud by 90%.

Senior Software Engineer

Sep 2019 – Sep 2022 · 3 yrs · On-site

Founding team member. Built core platform infrastructure from scratch across DeFi and fintech verticals.
Nuo Network (DeFi Protocols):
▸ DEX Aggregation & Optimization: Architected an aggregated swap protocol using a fractional knapsack-based solver with atomic on-chain execution via the XSplit proxy contract; optimized execution prices by 12% by routing trades across 0x, Kyber, and Uniswap.
▸ Nuoscan Integration: Developed public read-only APIs for protocol transparency, exposing real-time transaction activity, volume metrics, and reserve utilization through a custom analytics engine.
Juno Core Platform (Early Build):
▸ Designed and built Juno's foundational banking backend on Synapse — accounts, cards, KYC, transactions, bill pay, cheque deposit, and crypto services from zero.
▸ Integrated Onfido for identity verification and laid the groundwork for the fraud detection framework.
▸ Led monolith-to-microservices transition, achieving 99.99% system uptime.
