Front End development (Sports Module) 𝐁𝐫𝐞𝐚𝐜𝐡𝐞𝐝 𝐂𝐨𝐧𝐭𝐫𝐚𝐜𝐭 𝐓𝐞𝐫𝐦𝐬: The freelancer agreed to support all bugs related to his work but ended the contract without resolving them.

𝐌𝐢𝐬𝐬𝐞𝐝 𝐃𝐞𝐚𝐝𝐥𝐢𝐧𝐞𝐬: He set the deadlines himself but missed them repeatedly.

𝐓𝐞𝐧𝐝𝐞𝐧𝐜𝐲 𝐭𝐨 𝐂𝐫𝐞𝐚𝐭𝐞 𝐌𝐨𝐧𝐨𝐩𝐨𝐥𝐲 & 𝐃𝐞𝐦𝐚𝐧𝐝 𝐄𝐱𝐭𝐫𝐚 𝐓𝐢𝐦𝐞/𝐌𝐨𝐧𝐞𝐲: He intentionally kept other developers in the dark about his work. As the project neared launch, he began playing dirty politics—blaming others and demanding more money to complete the job. During this contract, he also had me open a second hourly contract, where he manipulated the timesheet entries for three consecutive weeks. Unfortunately, I was able to recover only one week as per Upwork’s dispute policy.

𝐌𝐢𝐬𝐛𝐞𝐡𝐚𝐯𝐢𝐨𝐫: He repeatedly misbehaved with other team members hired through Upwork. Warned him multiple times, and he promised to maintain professionalism but failed.

𝐑𝐞𝐬𝐮𝐥𝐭: My project suffered a massive setback due to his lack of cooperation and toxic attitude, which demotivated others and created a hostile work environment.

𝐁𝐞 𝐀𝐰𝐚𝐫𝐞:
# If you choose to work with this freelancer, proceed with a milestone-based contract after clear negotiations.
# Closely monitor whether he's doing the work himself or outsourcing it, as I found his actual competency did not match the claims in his profile.
# Be prepared to deal with a tendency to play the victim when challenged, often deflecting blame instead of taking responsibility for mistakes.

Lead Front End Developer & API integration (long Term) 🚫 𝐔𝐧𝐫𝐞𝐥𝐢𝐚𝐛𝐥𝐞 𝐚𝐧𝐝 𝐌𝐢𝐬𝐥𝐞𝐚𝐝𝐢𝐧𝐠 – 𝐍𝐨𝐭 𝐅𝐢𝐭 𝐟𝐨𝐫 𝐈𝐧𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐭 𝐨𝐫 𝐋𝐞𝐚𝐝 𝐑𝐨𝐥𝐞𝐬

🚨I had a very disappointing experience with this freelancer. For three consecutive weeks, he provided 𝐮𝐧𝐫𝐞𝐚𝐥𝐢𝐬𝐭𝐢𝐜 𝐚𝐧𝐝 𝐮𝐧𝐣𝐮𝐬𝐭𝐢𝐟𝐢𝐞𝐝 𝐭𝐢𝐦𝐞𝐬𝐡𝐞𝐞𝐭 𝐞𝐧𝐭𝐫𝐢𝐞𝐬, leading to 𝐨𝐯𝐞𝐫𝐛𝐢𝐥𝐥𝐢𝐧𝐠 . Despite claiming the work was progressing, I discovered he had misrepresented his efforts. I was able to 𝐝𝐢𝐬𝐩𝐮𝐭𝐞 𝐨𝐧𝐞 𝐰𝐞𝐞𝐤'𝐬 𝐭𝐢𝐦𝐞𝐬𝐡𝐞𝐞𝐭, 𝐚𝐧𝐝 𝐔𝐩𝐰𝐨𝐫𝐤 𝐫𝐮𝐥𝐞𝐝 𝐢𝐧 𝐦𝐲 𝐟𝐚𝐯𝐨𝐫 —confirming the issue.

🚨He was initially assigned as the Lead Frontend Developer among a team of 12 Upwork hires. However, his behavior was far from collaborative. He often 𝐜𝐥𝐚𝐬𝐡𝐞𝐝 𝐰𝐢𝐭𝐡 𝐭𝐞𝐚𝐦 𝐦𝐞𝐦𝐛𝐞𝐫𝐬 𝐚𝐧𝐝 𝐜𝐫𝐞𝐚𝐭𝐞𝐝 𝐚 𝐭𝐨𝐱𝐢𝐜 𝐞𝐧𝐯𝐢𝐫𝐨𝐧𝐦𝐞𝐧𝐭, leading to project delays. He is not suited for team or leadership roles.

🚨 𝐀𝐝𝐝𝐢𝐭𝐢𝐨𝐧𝐚𝐥𝐥𝐲, 𝐡𝐞 𝐝𝐞𝐥𝐢𝐛𝐞𝐫𝐚𝐭𝐞𝐥𝐲 𝐰𝐢𝐭𝐡𝐡𝐞𝐥𝐝 𝐚𝐜𝐜𝐞𝐬𝐬 𝐭𝐨 𝐡𝐢𝐬 𝐰𝐨𝐫𝐤 𝐚𝐧𝐝 𝐬𝐥𝐨𝐰𝐞𝐝 𝐝𝐨𝐰𝐧 𝐩𝐫𝐨𝐠𝐫𝐞𝐬𝐬, 𝐭𝐚𝐤𝐢𝐧𝐠 𝐚𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐭𝐫𝐮𝐬𝐭 𝐈 𝐩𝐥𝐚𝐜𝐞𝐝 𝐢𝐧 𝐡𝐢𝐦. 𝐓𝐡𝐢𝐬 𝐚𝐩𝐩𝐞𝐚𝐫𝐞𝐝 𝐭𝐨 𝐛𝐞 𝐚 𝐭𝐚𝐜𝐭𝐢𝐜 𝐭𝐨 𝐨𝐯𝐞𝐫𝐛𝐢𝐥𝐥 𝐚𝐧𝐝 𝐠𝐚𝐢𝐧 𝐥𝐞𝐯𝐞𝐫𝐚𝐠𝐞 𝐨𝐯𝐞𝐫 𝐭𝐡𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭’𝐬 𝐛𝐮𝐝𝐠𝐞𝐭. 𝐔𝐧𝐟𝐨𝐫𝐭𝐮𝐧𝐚𝐭𝐞𝐥𝐲, 𝐛𝐲 𝐭𝐡𝐞 𝐭𝐢𝐦𝐞 𝐈 𝐫𝐞𝐚𝐥𝐢𝐳𝐞𝐝 𝐭𝐡𝐞 𝐞𝐱𝐭𝐞𝐧𝐭 𝐨𝐟 𝐭𝐡𝐞 𝐦𝐚𝐧𝐢𝐩𝐮𝐥𝐚𝐭𝐢𝐨𝐧, 𝐢𝐭 𝐡𝐚𝐝 𝐚𝐥𝐫𝐞𝐚𝐝𝐲 𝐜𝐚𝐮𝐬𝐞𝐝 𝐬𝐞𝐫𝐢𝐨𝐮𝐬 𝐝𝐞𝐥𝐚𝐲𝐬, 𝐥𝐞𝐚𝐯𝐢𝐧𝐠 𝐦𝐞 𝐧𝐨 𝐜𝐡𝐨𝐢𝐜𝐞 𝐛𝐮𝐭 𝐭𝐨 𝐫𝐞𝐦𝐨𝐯𝐞 𝐡𝐢𝐦 𝐟𝐫𝐨𝐦 𝐭𝐡𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭.

🚨I also discovered he was acting as a 𝐦𝐢𝐝𝐝𝐥𝐞𝐦𝐚𝐧, 𝐨𝐮𝐭𝐬𝐨𝐮𝐫𝐜𝐢𝐧𝐠 𝐰𝐨𝐫𝐤 𝐭𝐨 𝐨𝐭𝐡𝐞𝐫𝐬 without informing me. This led to missed deadlines and vague timelines. Even simple tasks were delayed due to this hidden delegation.

🚨He struggled to collaborate with backend developers, often due to his poor communication and unprofessional attitude. He repeatedly billed for the same tasks without delivering results.

❌𝐁𝐞 𝐜𝐚𝐮𝐭𝐢𝐨𝐮𝐬: 𝐡𝐞 𝐢𝐬 𝐧𝐨𝐭 𝐚 𝐭𝐫𝐮𝐞 𝐟𝐮𝐥𝐥-𝐬𝐭𝐚𝐜𝐤 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫. 𝐇𝐢𝐬 𝐭𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐞𝐱𝐩𝐥𝐚𝐧𝐚𝐭𝐢𝐨𝐧𝐬 𝐰𝐞𝐫𝐞 𝐰𝐞𝐚𝐤, 𝐚𝐧𝐝 𝐡𝐞 𝐫𝐞𝐥𝐢𝐞𝐝 𝐨𝐧 𝐨𝐭𝐡𝐞𝐫𝐬 𝐭𝐨 𝐜𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐭𝐡𝐞 𝐰𝐨𝐫𝐤. 𝐈 𝐞𝐯𝐞𝐧 𝐬𝐮𝐬𝐩𝐞𝐜𝐭𝐞𝐝 𝐭𝐡𝐞 𝐮𝐬𝐞 𝐨𝐟 𝐬𝐜𝐫𝐢𝐩𝐭𝐬 𝐨𝐫 𝐛𝐨𝐭𝐬 𝐭𝐨 𝐥𝐨𝐠 𝐢𝐝𝐥𝐞 𝐡𝐨𝐮𝐫𝐬. ❌

𝐑𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧: If you must work with him, limit the scope to milestone-based tasks after a thorough technical interview. Do not assign him critical or complex responsibilities.

I often work with founders and startups to turn an idea into a solid, well-architected version that’s built to grow. Once the concept is proven, I help scale it into a full product.

My focus is on building software that is reliable, fast, and straightforward to maintain. Whether it’s a SaaS platform, an e-commerce system, or a mobile app, I build with the future in mind so you don’t have to rebuild later.
