About

Senior Software Engineer and Systems Architect with 8+ years of experience designing real-time AI pipelines, high-concurrency backends, and scalable cloud architectures.

I build software with a founder’s commercial mindset: engineering excellence must directly drive customer acquisition and business growth. As the Founder and Principal Engineer of CiteVerse (https://citeverse.live), I took a real-time AI speech processing platform from 0 to 1, scaling it to 225+ users and paying subscribers across Canada and France.

Whether you need to architect a 0-to-1 MVP, scale low-latency AI workflows, or refactor existing backend services for high throughput, I deliver production-ready software built for speed, security, and uptime.

What I Bring:

• Real-Time AI & Agent Systems: Deep expertise orchestrating LLMs with OpenAI, AssemblyAI, and Pydantic structured outputs over low-latency WebSockets. I design minimal-hallucination systems where your database controls the deterministic source of truth, and AI is strictly constrained to high-precision extraction.

• High-Concurrency Backends: Production mastery in TypeScript/Node.js, Python (FastAPI), and Go. Re-architected core ingestion layers from Python to Go to eliminate event-loop latency and leverage concurrent goroutines.

• Enterprise Cloud & Distributed Systems: Engineered HIPAA-compliant data pipelines at Vori Health using AWS SQS FIFO queues to guarantee strict sequential ordering across 10,000+ active healthcare users, processed batch datasets exceeding 1M records, and increased deployment capacity by 3,000% via Docker containerization on AWS ECR.

• Full-Stack Delivery: Production expertise spanning Next.js, React, PostgreSQL (schema indexing & optimisation), MongoDB, Redis, and automated GitHub Actions CI/CD.

Core Stack:

• Languages & Backends: TypeScript, Node.js, Python (FastAPI), Go

• Frontend: React, Next.js, WebSockets, Tailwind CSS

• Databases: PostgreSQL, MongoDB, Redis, SQL, NoSQL

• Cloud & DevOps: AWS (SQS FIFO, ECR, S3), Docker, Kubernetes, Nginx, CI/CD

Based in Ontario, Canada (Canadian Citizen), I work across North American time zones (EST) with clear async communication and rapid iteration.
