Background & Practical Competencies
I combine a Bachelor of Commerce background with deep self-directed engineering practice in Go, Rust, and systems security. I approach software through both operational viability and technical resilience.
Technical Knowledge Matrix

LiveInbox Engineering Journey
Go SpecializationWhat I learned & engineered building a production email deliverability engine from scratch in Go.
Core SMTP Engine in Go
Dove deep into low-level email protocols. Wrote a Go verification engine that checks mailbox existence using direct SMTP handshakes (EHLO, MAIL FROM, RCPT TO) without transmitting actual messages.
DNS MX Lookups & Network Handshakes
Implemented automated DNS querying for MX host priority records, socket connection establishment, and categorization into valid, invalid, and catch-all classifications.
Rate Limiting & IP Reputation Protection
Built adaptive rate-limiting algorithms to safely query external mail exchangers without triggering spam defenses or IP blacklisting.
Go REST API with Chi Router
Wired the core verification logic into a clean, lightweight REST API utilizing the chi router for low routing latency and idiomatic Go middleware.
PostgreSQL & Redis Integration
Connected Go services to PostgreSQL for structured verification records and Redis for in-memory session caching and rate token management.
DevOps & Docker Compose
Containerized the entire multi-service stack (database, cache, and Go API) in Docker Compose, and configured DigitalOcean hosting with Nginx reverse proxying.
