Shaik Sameer

At Tayseer Technologies, I build and maintain features across Chrona and Leshub, working from the UI through to the database. On Chrona, I reduced bulk hour entry and timesheet creation from 45–50 seconds to 1–2 seconds by replacing looped stored procedure calls with batched operations and transaction rollbacks. At Tayseer Technologies, I also integrated Mollie payments and Puppeteer PDF invoices, added Dutch and English localization, and wrote tests for login and timesheet flows. I work on performance and security, including database batching, encrypted API payloads, and secure session handling. Previously at Graviti Chain, I built and deployed full-stack apps and worked on APIs, authentication, payments, and AWS deployments. I’m now building my skills in Python, RAG, LLM apps, and agent workflows as I move toward AI Full Stack and AI Engineer roles.
