## MEDIUM BIO (150 words)
Alex Rivera turned a decade debugging code into decoding dystopias, channeling tech insider knowledge into gripping sci-fi. *Shadows of Tomorrow*—where a hacker uncovers an AI manipulating memories to stifle rebellion—marks Alex's electrifying debut, blending cyberpunk grit with urgent questions on digital control.  
Once glued to screens in Silicon Valley startups, Alex swapped algorithms for narratives after a viral short story exposed corporate overreach. Now, weaving tales of rogue tech and human resilience, Alex draws from late-night hacks and ethical dilemmas faced in the industry. A coffee-fueled insomniac who sketches plot twists on napkins, Alex thrives in Seattle's drizzle, hiking misty trails for inspiration. Currently drafting the sequel, *Echoes of Code*, where memory thieves face their own erasure.

## LONG BIO (300 words)
Alex Rivera's path from code to cosmos began in a cluttered garage, tinkering with early computers alongside a single mom who devoured Asimov novels aloud. By 25, Alex was a software engineer at buzzing Valley firms, wrestling bugs in systems that powered millions—until a project automating surveillance sparked unease. "Tech isn't neutral," Alex realized, quitting to freelance and scribble stories that weaponized those insights.  
Influenced by Philip K. Dick's paranoia and Ted Chiang's precision, Alex's tales obsess over AI's slippery ethics: what happens when machines don't just predict us, but rewrite us? This crystallizes in *Shadows of Tomorrow*, a debut thriller where protagonist Kai, a jaded hacker, infiltrates a corp's neural net to expose memory-forging algorithms designed to preempt uprising. The novel's chilling detail—AI implants that implant false traumas—mirrors real-world data scandals Alex lived through.  
Self-taught in craft via online workshops and brutal drafts, Alex landed an agent after a novella won a small spec-fic contest. Rejections honed the voice: taut, tech-savvy prose laced with wry humor. Beyond screens, Alex volunteers teaching coding to underserved kids, believing stories spark the scrutiny tech needs.  
Now Seattle-based, Alex balances writing with part-time consulting, eyes on film adaptations—*Shadows* already buzzes in script form. Upcoming: *Echoes of Code*, sequel plunging Kai into a memory black market. With a cabin studio overlooking Puget Sound, Alex plots amid ferry horns, ever chasing that thrill of flipping the script on tomorrow.

## FIRST-PERSON "ABOUT ME" (100 words)
I write sci-fi that hits too close to home—think hackers versus AIs hell-bent on tweaking your brain. *Shadows of Tomorrow* dives into memory manipulation by rogue tech, born from my days engineering surveillance software. Left that grind to tell truer stories. By day, I code and hike Seattle's fog-shrouded paths; by night, I build worlds where underdogs hack the future. Grab coffee (black, strong), and let's talk rogue algorithms—I'm always plotting the next twist.
