Reading Namaso was born in
Reading, Berkshire, and started his career in the youth team of
Wycombe Wanderers before joining the under-13 side at his hometown club
Reading in 2012. He studied at
Leighton Park School and then
The Forest School. In 2016 he won the Maurice Edelston Memorial Trophy for the best academy schoolboy at the club. In the summer of 2016 he started a two-year scholarship, but was quickly promoted to the under-23 side after a number of games and went on to represent the side in the
EFL Trophy campaign. Prolific for the youth team, he was given a chance in the first team under
José Gomes and became the youngest Reading player to reach 20 appearances. On 27 April, he scored his first senior goal against
Middlesbrough. Namaso was close to a move to
Wolverhampton Wanderers before Wolves pulled out of the move due to Reading upping the price at the last moment. A few days later he scored the winning penalty in round 2 of the
EFL Cup against
Wycombe Wanderers.

FC Porto announced the signing of Namaso for
Porto B, on a two-year contract. He made 32 appearances for the reserve team in his first season, finishing with 8 goals, the highest tally on the team. Namaso began the following season with Porto B and went on to score 15 goals. He was named in the senior squad for the first time for a league match against
Boavista on 30 October. He came off the bench late in the match to replace centre-forward
Evanilson, and he scored in added time, sealing a 4–1 win. Namaso started the
2022–23 season by winning the
Supertaça Cândido de Oliveira after being handed a surprising first start for Porto in a game that they ran out 3–0 winners over
Tondela. On 23 January 2024, Namaso extended his contract with Porto until June 2028.
