Results-driven Senior Engineer looking for a fully remote role. I bring 7+ years of experience in translating business needs into technical solutions efficiently. I am looking for a team that trusts senior developers to manage their own time and output, allowing for high efficiency and focused execution without micromanagement.

Senior automation architect driving AI-native engineering and scalable systems.
What I'm looking for
I am a senior automation architect and AI-native developer focused on transforming manual operations into self-driving software solutions. I combine deep backend engineering experience with AI-driven automation to deliver high-scale, reliable systems.
At Shopee I led a 9-month migration of a Voucher Management System from Python to Go, refactoring legacy workflows into maintainable microservices and improving system extensibility under high concurrency. I also designed operational tooling that reduced engineering support tickets by roughly 30%.
As a technical co-founder I built and scaled a B2B payment aggregation SaaS single-handedly, integrating over 300 upstream payment providers and achieving the throughput of a three-person engineering squad through LLM-assisted development and AI agents.
I prioritize operational reliability, security, and efficiency—implementing OWASP standards, TLS/AES encryption, automated access monitoring, and reconciliation workflows that reduced manual operations to under five hours per week while maintaining 99.9% uptime.
