What I'm looking for

I’m aiming toward a Technical / Solution Architect role, focusing on system design and scalable service patterns while bridging business strategy with engineering execution.

I’m a Full-Stack Developer with 5+ years delivering production web products for international clients across FinTech, EdTech, and enterprise domains. I own end-to-end delivery, designing and implementing frontend, backend, API, and database layers.

Recently, I engineered checkout, KYC, and IVR flows for a BNPL payments platform and built centralized logging and monitoring with Elasticsearch and Kibana. I also developed admin tooling and built scalable backend services for warehouse, inventory, staff management, and delivery modules, translating stakeholder requirements into RESTful APIs and database schemas.

I’m currently aiming toward a Technical / Solution Architect role, with a growing focus on system design and scalable service patterns—bridging business strategy with engineering execution.
