Full-Stack Software Developer

Shipping production SaaS, data pipelines, and cloud infrastructure — from schema design to CI/CD deployment.

01 / About

From schema design
to CI/CD deployment

I'm a full-stack software engineer with 3+ years of experience shipping production SaaS products, data pipelines, and cloud infrastructure. I work across Node.js, React, FastAPI, and PostgreSQL — owning everything from schema design to CI/CD deployment.

Currently at Buzzinga Co, I've architected three products end-to-end: multi-tenant SaaS platforms with Stripe billing and RBAC, async AI pipelines (BullMQ, Redis, AssemblyAI, OpenAI), and a B2B cybersecurity compliance platform. Previously I rebuilt data pipelines with Apache Spark at Nasdaq Verafin and cut API latency in half migrating Firestore to PostgreSQL at Simform Solutions.

I hold a Master of Applied Computer Science from Dalhousie University, Canada, and I'm an AWS Certified Solutions Architect – Associate.
