Principal Software Engineer | Technical Team Lead | Fintech system architect 🇨🇦
I am a hands-on technical leader with over 20 years of experience traversing the full infrastructure-to-application spectrum—from System/DB Admin to Software Architect and Engineering Manager.
I don't just design systems; I build them. My background allows me to bridge the gap between complex architectural vision and operational reality, identifying root causes quickly and adapting stacks to business evolution.
- Complex System Integration: Deep expertise in diverse integration patterns (ESB, Event-Driven, API Gateways) within mission-critical Banking/Fintech environments. I possess a sharp instinct for diagnosing architectural bottlenecks and architecting resilient, fail-safe solutions.
- Polyglot Engineering: Fluent in Java, Golang, Python, and Typescript/Node.js. I don't follow hype; I pick the right tool for the job.
- 0 → 1 Builder: Successfully launched multiple products from scratch to revenue generation ($1M+), balancing speed-to-market with long-term maintainability.
- Scalability Mindset: Experience in modernizing legacy monoliths into distributed microservices on AWS or apply a cloud-agnostic approach.
- Leadership: Experience managing teams of 10–30 engineers while staying technically active (code reviews, RFCs, core implementation).
Languages & Core: Java Golang Python TypeScript/Node.js SQL Microservices
Industry Experience:
- Banking & Fintech: Core banking modernization, Payment Gateways, Digital Lending, e-Wallets.
- Travel Tech: High-concurrency Airline Reservation Systems (ARS), Hotel Inventory.
- Retail & Commerce: POS, ERP integrations, large-scale E-commerce platforms.
