Sources vary on Łukaszewycz's birth details: some record 1920 in Tarnopol while others specify 22 June 1922 in Przemyśl. He completed his secondary education at a gymnasium in Tarnopol.
In 1943, during World War II, Łukaszewycz joined the German-sponsored 5th SS Police Regiment (Galician), a unit composed largely of Ukrainian personnel. In spring 1944, he deserted alongside a group of fellow soldiers and aligned with the Ukrainian Insurgent Army, an anti-Soviet and anti-Polish nationalist force. He initially joined a UPA unit under the command of "Oczeret" in the Hrubieszów county region.
Łukaszewycz rose rapidly in the UPA ranks. He soon took command of the sotnia (company) "Wowky" and was promoted to major. His forces engaged in numerous clashes with Soviet partisans, NKVD troops, and units of the Polish People's Army. By the second half of 1944, he organized and led the larger kurin (battalion) "Wowky," which incorporated three sotnias: "Wowky-1," "Wowky-2," and "Wowky-3." In early 1945, he assumed command of Tactical Sector 28 "Danyliw," overseeing all UPA operations in the Chełm region and Podlasie, including sotnias such as Czausa, Dawyda, Dudy, and Jara. After his death, command passed to "Berkut."
Łukaszewycz's tenure is linked in Polish historical accounts to the "Bloody Palm Sunday" attack on the village of Kryłów on 25 March 1945. Disguised in Soviet uniforms, his UPA sotnia assaulted a Milicja Obywatelska post, resulting in the deaths of 17 militia officers and 28 civilians including former major of Peasant Battalions, Stanisław Basaj "Ryś" .
On 9 September 1945, Łukaszewycz was burned alive in field hospital near Żniatyn by Milicja Obywatelska during a skirmish between Milicja and his unit in retaliation for the Massacre that he committed in Kryłów and the murder of "Ryś" . He is commemorated in UPA folklore through the marching song "Do boju prawoho, do boju stawajmo" ("To the righteous fight, let us stand"), dedicated to "Jahoda."
