  • image of M K. Project for Leonid R. £75.00 GBP

    “I approached Leonid again based on the first commission he did for me, and as expected, he did not disappoint. As already practised, I will be commissioning Leonid for repeat work based on the strength of his expertise and professionalism.”

  • image of M K. Poorly Recorded Audio - Remove Noise And Sharpen Conversation £100.00 GBP

    “Leonid was faced with an extremely challenging audio recording that had a lot of background noise with multiple parties involved in a conversation. He was able to hone into the voice requested and was patient in going through iterations of the restored audio to suit my requirements, focussing on key-times and phrases to make them clearer. To also add, Leonid was very accommodating as it was my first employment project and kindly talked me through some Freelancer website process steps that were required for a successful Freelancer experience. He also delivered the restored audio earlier than expected, in fact on the same day, which was a very nice surprise. I would highly recommend Leonid for his expertise, patience, timeliness, and adherence to confidentiality and data retention regulations (i.e. GDPR or local equivalent). I will be hiring him again for projects of a similar nature.”

  • image of Zahraa A. Making an Instrumental version of a Song $650.00 USD

    “The type who can give me a peace of mind. Professional + Experienced + Friendly + Communicative. He knew exactly the kind of feeling I wanted from the track. Even though I rushed him to finish it in 1 day, yet he did it with a satisfying result.”
