Hire the Best Data Engineers
in the Philippines

Hello! I'm John Lee, a Software Engineer with 9 years of professional experience in the IT industry who is now building my experience and reputation as a freelancer on Upwork. While I am new to freelancing, I am not new to professional work. My engineering background has trained me to handle information accurately, follow detailed processes, perform repetitive tasks consistently, identify errors, and document my work carefully. I am primarily looking for opportunities involving: • Data Entry & Data Processing • Virtual Assistance / Administrative Support • Excel & Google Sheets • Data Cleaning, Collection & Research • PDF, CSV, JSON & Database Data Handling • Transcription & Document Formatting • QA, Manual Testing & Data Verification • AI-Generated Data/Output Review I am highly proficient with Microsoft Office and experienced in handling information across Excel, CSV, JSON, databases, and PDF documents. I also have professional experience with QA/testing, bug reporting, documentation, requirements analysis, and process automation. My key strengths are attention to detail, patience with repetitive work, consistency, technical literacy, fast learning, and the ability to follow instructions and SOPs carefully. When information is unclear or conflicting, I prefer to verify or flag it rather than make assumptions. I also regularly use AI tools in my professional work and understand the importance of manually reviewing AI-generated information for inaccuracies and inconsistencies. I may be new to Upwork, but I bring 9 years of professional discipline and experience with me. I am happy to start with smaller projects or test tasks and let the quality and accuracy of my work speak for itself.
