About Me
A quick introduction to how I work, what I build, and the kinds of engineering problems I enjoy solving.
Profile
I'm a backend-focused senior full-stack engineer who likes building web apps, production APIs, AI-powered features, and n8n automations that solve real business problems.
Most of my work has been around HRMS, ATS, payroll, permissions, and internal platforms used by 100K+ users across multiple countries. I care a lot about clean backend architecture, reliable data, and business logic that stays easy to understand, extend, and operate.
I enjoy taking messy workflows and turning them into systems that are easier to trust: clear domain models, RBAC boundaries, faster queries, caching, integrations, and event-driven flows.
I also like building practical n8n automations for sales bots, daily reminders, and sales analysis. Even this portfolio runs on automation, with a daily cron sync from my Notion notes into a living engineering knowledge base.
