What I'm looking for

I'm looking to build clean, reliable backend systems with Python or Node.js, work on APIs and transactional business logic, and grow through collaborative engineering practices such as code reviews and Scrum.

I've built RESTful APIs and refactored backend modules at Makichyan Consulting, using Django, FastAPI, and MS SQL Server to improve performance and maintainability. At STA Soft, I refactor Python business logic into Node.js and TypeScript, build transactional workflows with Knex, and integrate LLM-based AI agents into backend services.

I also bring clinical-data experience from STATECS, where I developed CDISC-compliant SDTM and ADaM datasets. I enjoy clean backend design, relational data modeling, code reviews, and collaborating across the stack with React when needed.
