About Me
I'm a Senior Backend Engineer and Solutions Architect with 5+ years of experience designing, building, and operating highly scalable, secure, cloud-native systems. I've worked across fintech, healthcare, legal tech, SaaS, and Web3 — delivering production-grade REST and GraphQL APIs, complex third-party integrations (payments, KYC, customer support), and multi-cloud infrastructure on AWS, GCP, and Azure.
My core stack is Node.js/TypeScript and Python (FastAPI, Django), with strong DevOps experience across Docker, Kubernetes, Terraform, and GitHub Actions CI/CD. I've integrated LLM/AI APIs for intelligent automation products and have deep roots in Web3 — having architected a soulbound-token governance platform for 3,000+ DAO members at SingularityNET. I'm also a published technical writer with 10,000+ developer readers.
I've recruited and led cross-functional engineering teams, established coding standards and PR review culture, and maintained high delivery velocity across complex, concurrent client products. I care deeply about security-first design, observability, and building systems that are as maintainable as they are performant.
What I Do
Solutions Architecture
End-to-end system design and technical strategy across fintech, healthcare, legal tech, and SaaS. Translating complex business requirements into scalable, maintainable, secure backend architectures.
DevOps & Cloud Infrastructure
Multi-cloud infrastructure on AWS, GCP, and Azure using Terraform IaC. CI/CD pipelines with Docker and Kubernetes, zero-downtime blue-green deployments, and Grafana/Prometheus observability stacks.
AI & LLM Integration
Integrating OpenAI and LLM APIs into production products. Custom prompt engineering pipelines, multi-tenant LLM systems, and intelligent automation workflows across web and social channels.
Web3 & Blockchain
Smart contract development with Solidity and Hardhat on EVM chains, and Anchor for Solana. DeFi protocols, soulbound token identity systems (ERC-5192), and DAO governance platforms.
Engineering Leadership
Recruiting, onboarding, and leading cross-functional teams of 5–6+ engineers. Establishing TypeScript/Python coding standards, PR review culture, documentation practices, and sprint-based delivery.
