During the weeklong semifinals running from February 20, 2017 to February 25, 2017, Mangubat performed songs corresponding to the theme of the day. On the fifth day, his performance of Renz Verano's "Remember Me" earned the first standing ovation of the semifinals and much praises from the judges. On the sixth day, Mangubat, who got the highest final combined average score of 95.35% from the judges and text votes, became one of the two finalists from the fourth Quarter of the competition to enter the Grand Finals.

The ten Grand Finalists were set to perform on the first five days (from March 6, 2017 to March 10, 2017) of the competition to earn a spot on the Top 5 who would then be competing for the title of Grand Winner at the "Huling Tapatan" at the Resorts World Manila. Mangubat performed "Ikaw" by Yeng Constantino on the second day for his first attempt to enter the Top 5, but he lost to Froilan Canlas after garnering only 75.35% combined average score from the judges and text votes. On his second attempt, he performed "Kilometro" by Sarah Geronimo and got a combined average score of 98.70% eventually becoming part of the Top 5.

On March 11, 2017, Mangubat competed with the five other Grand Finalists who were able to get their slots to perform at the "Huling Tapatan" at the Resorts World Manila. On the first round, he performed "Fall for You" by Secondhand Serenade. After garnering one of the three highest final combined score from text votes and judges' scores, he advanced to the second and final round where he performed a Bruno Mars' medley of "Nothin' On You", "Locked Out Of Heaven", and "Treasure". He finished 2nd place garnering a combined score of 49.09%.

After Tawag ng Tanghalan, Mangubat, together with other finalists, were invited to perform on several TV shows and events (e.g. Bar 360, Laffline, Historia, mall shows and private events). He was one of the 18 artists who performed the 2017 summer station I. D. of ABS-CBN titled "Ikaw ang Sunshine Ko". Together with Marielle Montellano, he also performed the anthem of K World, a magazine show broadcast on TFC. Furthermore, together with other Tawag ng Tanghalan singers, he was inducted as an official member of Organisasyon ng mga Pilipinong Mang-aawit (OPM).

On September 2017, Mangubat officially signed a record deal with Star Music. His first released song from the label is an all-star special 2017 Christmas cover version of the song "Tell the World of His Love". The label also released his first solo single called "Pagka't Nariyan Ka" on early January 2018. He officially launched the song in It's Showtime and subsequently promoted in various F.M radio stations.

On January 16, 2017, Mangubat was chosen by online voters and a board of judges from the music industry as the Wish Promising Artist at the 2nd Wish 107.5 Music Awards at the SMART-Araneta Coliseum. Mangubat was also nominated in Push Awards 2017 for Push Song cover of the year for his cover of "Beautiful" (duet with Marielle Montellano). However, he lost to Morissette Amon.

On August 16, 2016, Mangubat participated in the third Quarter of Tawag ng Tanghalan (TNT) sa Showtime, a singing competition broadcast on ABS-CBN. He was introduced as a YouTube cover artist and was dubbed the "Uploaded sa Galing ng Laguna" (it was later changed to "Uploaded sa Galing ng Batangas" in his second attempt due to his transfer of residence from Laguna to Batangas). On his first performance, he delivered his rendition of "Secrets" by OneRepublic. Rey Valera, one of the judges, commented that Mangubat's voice seemed to fit better on the rock ballad genre and that it sounded "imported". Garnering an average score of 94.4% from the judges, Mangubat won against the two other contenders vying to challenge the current defending winner. On his second performance, he sang "Flying Without Wings" by Westlife for which he garnered an average score of 95.6% eventually beating the defending champion. His winning streak continued until the fifth day when he lost to the daily winner missing his slot in the semifinals of the quarter.

On November 19, 2016, Mangubat returned to the competition, already in its fourth Quarter, for another chance of being one of the semifinalists. On his first performance, he sang "Love Runs Out" by OneRepublic. Valera commented that Mangubat got the right image, moves, energy, intelligence, and talent, but cast some doubt on whether he has grown wiser and luckier on his second attempt. Garnering an average score of 95.4%, Mangubat won the first round and became the daily winner. On his second performance, he sang "When We Were Young" by Adele where he got an average score of 96.6% eventually beating the defending champion. He won again on his second day with "Incomplete" by Backstreet Boys. On his third day, however, he made an apparent mistake with the abridged lyrics of the song "All Or Nothing" by O-Town which disappointed the judges prompting Valera to call the performance "palpak" (failure). Despite this, after looking into all considerations, the judges still ruled in favor of Mangubat. His wins continued up to the fifth day making him the third semifinalist of the quarter. He remained the defending champion until his eighth day when he lost to the daily winner.

Intermittently since 2016, Mangubat, together with his three-member vocal group Dreamzone (includes Shane Tarun and Jun Sisa), has been regularly performing on various cruise ships around Asia. He has also kept uploading new performances in his YouTube channel through his Dreamzone Productions.

In early 2015, Mangubat became one of the regular performers in Club Se7en in Dubai, U.A.E. He continued uploading new covers to his YouTube channel featuring his fellow club singers and musicians. After one and a half year, he left the job and decided to return to the Philippines to try some new ventures.

Mangubat created his YouTube channel on June 28, 2006. His uploaded performances on YouTube consist of both covers and original songs. They are performed either solo or in collaboration with other artists and are recorded through portable devices. Due in part to the popularity of some of his covers in his YouTube channel, he was featured on several television programs such as CgeTV In Da Loop and ASAP, both broadcast on ABS-CBN. This growing online visibility also prompted him to self-produce a demo album titled Strong Inside, which includes original compositions such as "Liwanag Para Sakin", "I Hope You're Proud of Me", "Strong Inside", and "Love Alone". The album was introduced on shows like Rise and Shine broadcast on UNTV and Tambalan sa DZRH News Television.
