Jubayer Hasan Minhaz

I’m a detail-oriented, tech-savvy freelancer with a strong background in data management, internet research, and digital assistance. I combine clear communication with an analytical mindset to help teams build reliable, high-quality outputs.

In my remote work as an Appointment Setter & Chat Support freelancer (October 2025–present), I manage day-to-day client communication, schedule virtual appointments, and maintain accurate records in Google Sheets. I’ve achieved 95%+ satisfaction rates by responding promptly, offering helpful technical assistance, and handling basic data entry and document consistency checks.

I’m also focused on data-centric AI support—seeking to apply my skills in Data Annotation, LLM Tuning, and Quality Assurance to provide high-quality datasets. Alongside this, I built and deployed a web-based investigation portal using Python and Flask (January 2026–March 2026), and I audited configurations, logs, and system errors during deployment for dependable performance.
