This is a bit of a longshot, but some of your elements match Splendini! by Scott Pinzon.
The main protagonist, Dave Scott, is a budding magician who styles himself as The Great Splendini, and one of the cores of the character is his Christian values. Sidekick is present with his friend AJ, who is a smart-alec in the same style as "Mouth" from The Goonies with a fondness for goofy T-shirts.
The plot is where this longshot may go off course. I cannot find any real text of the book, and actually, the best I can find for a plot summary comes from this Amazon review:
The Great Splendini! is better known as pre-teen Dave Scott, with a newfound secret - he's recently converted to Christianity. He's also got a not-so-secret - his dad works for Compudat, a major computing and hardware company rumored to be producing super secret technical wonders for the government. Dave's worried that his new faith will alienate him from his best friend, the goofy and smart-alek AJ, fond of wearing t-shirts bearing slogans like "Be Alert - the world needs more lerts" and "Pobody's Nerfect."
Dave, AJ, and moody newcomer Sylvia (with dark secrets and problems of her own) all attend a summer tour of the Compudat building, courtesy of Dave's dad. The tour is cut short by espionage. Shortly thereafter, things go from bad to worse as first AJ, then Sylvia, then Dave are all kidnapped and held until Dave's dad delivers the secret plans that the criminals failed to steal during their botched theft during the kids' tour.
The most memorable section of this short novel is the captivity and escape attempt itself. The teens are held in an abandonned carnival on an island. The carnival is described in gleeful detail - all of the derelict and rusted rides, the shorted lights, all building the creepy anticipation of an ensuing chase through mirror-mazes or rusted roller-coaster struts. They use their different strengths - stage magic, physical strength, and super-smarts respectively, to formulate an escape plan and foil their kidnappers.
So, computer plot, check, but no space station mentioned, brilliant scientist might be the dad (a stretch, I think), and the amusement park sounds like it'd be something that'd stand out.
It does have a sequel that swaps kidnappers for a jock gang into petty crimes trying to pull a big steal for their initiation. Other than these two books, however, there is no further series.
