What I'm looking for

I’m looking to build secure, fintech-grade backend services and blockchain infrastructure—shipping API-driven systems in fast-paced teams. I want to learn from experienced engineers while contributing reliable features under tight deadlines.

I’m a self-taught backend developer with hands-on experience building APIs, backend services, and blockchain infrastructure through personal projects and hackathons. I’m comfortable with Rust, Go, and TypeScript, and I focus on solid engineering fundamentals like APIs, databases, and version control.

I built iWallet, a backend prototype for an AI-Agent banking system, where I developed backend services and a CLI to handle automated transaction logic and signing during a 7-day hackathon sprint. I shipped under competition deadlines while collaborating to integrate backend workflows into a working product.

I also created Mothrbox, an encrypted storage CLI and API development effort using gRPC and an event-driven architecture (Kafka), with REST support. I integrated encryption using AES-256-GCM and explored AWS Nitro Enclaves to support isolated compute, with a strong emphasis on secure-by-design patterns for sensitive data.

On the cryptography side, I built Soroban-ZK-Std, a zero-knowledge primitives library (elliptic curve and hash-based) for smart contracts on the Soroban platform. I set up a CI pipeline with automated testing, memory-safety checks, and binary size limits to keep the library reliable and lightweight, and I’ve also facilitated workshops to help early-career developers learn backend and blockchain concepts.
