Dear client, It's good to see another serious job posting here! I have read your project skill requirement and potentially found this job is highly good match with me for experience and skills hence I would like to submit my proposal as a potential candidate. As you can see my profile, I am good software developer/engineer with 8 years of experience of software development. Especially, python, SQL code review and optimization work are my past expertise and rich experience, that's why, I can give fast and clean deliveries by putting my honest efforts during weekends and holidays. Therefore I think, I can be the person you want to hire here. I am sending proposal for one time contract but hopefully, this can be first step for our long term relationship. Thank you for reading and I look forward to hearing from you soon. Your invitation over a private chat would be highly appreciated. Best Regards! Widad Saghir
