Mahin Kadery

Kogarah, Sydney

Cleaning supervisor and trainer — I run teams and show new starters how to do the work properly.

Police-checked teamSydney-wide

I supervise cleaning teams across Sydney — university campuses with GJK, gym sites in Bondi with White Spot Group, and retail floors with AFS Cleaning Services. Day to day that means allocating the work, inspecting what gets handed back, and keeping the site safe with the chemicals and machinery.

A lot of my work is floor care: strip-and-seal restoration on Kmart floors, machine scrubbing, edge work, sealing and polishing on overnight projects. I have also done deep cleans in childcare centres, retail stores like UNIQLO and Chemist Warehouse, and secure sites including police stations.

The part I enjoy most is training. Most people get sent onto a job and never properly shown how to do it, so I take new starters through the equipment, the chemical handling and the standard until they can run their own area confidently.

I started GenZ Tradies to bring that same standard to my own clients. If I have trained you or worked alongside you, I would genuinely value your honest feedback below.

He taught me strip and seal from scratch at Warringah Mall. I had never touched a polisher before. Now I run my own edge work. Best trainer I have had in this industry.

Reply from Mahin

Proud of how far you have come Nabin. You do the edges better than me now.

Worked with Mahin on the Kmart strip and seal jobs at Broadway. He plans the night properly so nobody is standing around waiting. Taught me the edge work and how much sealer to actually put down.

Reply from Mahin

Thanks Suman. You were quick to pick up the edges, made those nights easy.

I met Mahin at a Bunnings site. I am a cleaner working on Bunnings sites under GJK. As a nee employee I had a bit lack of knowledge about operating machines on site, along with some detailing issues. Later he was assigned as my trainer and I am doing pretty good now. He’s well spoken and knows what he’s doing. It was a great experience with him

Mahin supervised me at the Bondi gym. He trained me on the sauna and change room routine and always made sure we had the stock we needed.

Reliable teammate on the Kmart deep cleans. Turns up on time, does his share and helps you finish yours. Cannot ask for more than that.

Worked alongside him on the UTS clean. Punctual, tidy and he communicates well if something needs to change during the shift.

Mahin was my supervisor and he made the roster clear and fair. If you did good work he would tell you, which not every supervisor does.

Operator with Mahin on the Broadway floors. He looks after the equipment and reports faults instead of ignoring them. Professional about the work.

He trained me on the strip and seal process at Kmart Woy Woy. Very patient and he let me do it myself while he watched instead of taking over.

Worked with him on retail sites. Mahin keeps the standard the same whether someone is watching or not. That is rare.

Good supervisor at the university and very fair with the team. Only thing is the shifts can start quite early, but that is the job not him. Would work with him again.

Trained under Mahin for childcare cleaning. He is respectful and does not make you feel stupid for asking questions. I appreciated that a lot.

Solid operator and a good teammate. We did overnight floor restoration together and his prep work is proper, which is why the finish comes out clean.

He is the one who taught me stain removal and machine scrubbing. Explains why, not just how. That made a big difference for me.

Worked with Mahin on the Lidcombe Kmart. Hard worker and he does not leave until the whole team is done. That says a lot about him.

Supervised me at Western Sydney Uni. Always on time, and he does the walk through with you rather than sending a message. You learn from him.

He trained me for retail cleaning at Hurstville. Showed me a proper order to do things so you are not going back over the same area twice. Saved me so much time.

Teammate on the UNIQLO Mid City deep clean. Mahin does the detail work most people skip, behind the fixtures and the corners. Standards are high with him.

Worked under Mahin at the university. He is calm when things go wrong, like a spill or an urgent call, and he sorts it without stressing the team.

He trained me on the childcare sites at Mount Hutton. Explained the chemical dilution properly instead of just telling me to get on with it. I felt confident after two shifts.

Operated the scrubber alongside Mahin at Chemist Warehouse. He knows the machines properly and showed me how to check the pads and not burn the floor. Safety first every time.

He was my supervisor at Western Sydney University. Fair with the work allocation and he actually checks the rooms after instead of just signing off. Good bloke to work under.

Mahin trained me for the childcare deep cleans at Bondi Junction. He is very particular about sanitising the high touch points and I understand now why that matters in a childcare room. Patient trainer.
