A native of Eastern Ukraine, Sachko started to play football in a local sports school of Velyka Novosilka Raion.

Until 2000 Sachko played primarily in amateur competitions for several clubs from Donetsk Oblast except for a short stint in 1998 when he defended colors of SC Tavriya Simferopol in the Vyshcha Liha.

With Shakhta Ukraina coached by Viktor Hrachov, Sachko managed to win the Ukrainian Amateur Cup by beating Volhynian team "Troianda-Ekspres".

In 2000 he joined the Second League Oskil Kupiansk and after a season received several offers from other professional clubs such as Naftovyk Okhtyrka, but chose to play for Volyn Lutsk.

Unable to find a regular spot in the starting squad, Sachko, with the approval of the Kryvbas officials, received a free agent status and on Wednesday, 20 August 2008 he moved to Vorskla Poltava.
