"What are you doing?" Derek asked, annoyed.
"Saving your ass," Jaime muttered.
She leaned over the table. On the back of the cheap recycled napkin, she wrote three lines of functional calculus. It wasn't code; it was the mathematical logic for the code.
"Don't verify the path," she said, circling the last variable. "Verify the empty space. Invert the algorithm. Don't look for where the drones are; look for where they aren't. It reduces the computational load by 90%."
She slapped the napkin onto the table, right on top of his tablet. "That's on the house," she said.
Jaime turned around and walked away, her heart hammering against her ribs like a trapped bird. She went to the back room, leaned against the industrial dishwasher, and exhaled.
Stupid, she thought. He's going to throw it away.
Back at table 4, Derek Sterling stared at the napkin. He reached for it, intending to crumple it up. He was a CEO; he didn't take advice from people who served muffins. But then his eyes caught the second equation.
He paused. He frowned. He pulled his tablet closer and typed a simulation command. He looked back at the napkin. His fingers started flying across the keyboard.
Three hours later, Jaime was clocking out. The rain had turned into a deluge. She pulled her hood up and stepped out the back door of the cafe, bracing herself for the long bus ride to the run-down district of Eastlake.
A sleek black sedan—a Tesla Model S Plaid—screeched to a halt right in front of her, splashing a puddle of oily water onto her jeans. The window rolled down. It was Derek Sterling, but he didn't look tired anymore; he looked electrified.
"Get in," he said.
Jaime took a step back, gripping the pepper spray in her pocket. "Excuse me?"
"I ran the simulation," Derek said, his eyes wide. "I ran it on a small batch. The efficiency jumped from 68% to 94%. We're 1% off the target. But I can't finish the integration. I don't understand the variable you used for the sigma parameter."
"That's the chaos variable," Jaime said, shouting over the rain. "It accounts for wind shear."
"Get in the car, Jaime," Derek pleaded. "Please. I will pay you. I will pay you for your time. Just explain the math to my CTO."
Jaime hesitated. This was dangerous; this was crazy. But she remembered the eviction notice on her counter. "$500," she said. "Cash. Tonight."
"Done," Derek said. "I'll give you a thousand."
Jaime opened the door and slid into the leather interior. It smelled like expensive cologne and fear.
They drove in silence to the Aerologics headquarters in downtown Seattle. The building was a glass monolith. Inside, the lights were blazing. A team of 20 engineers was running around like headless chickens. When Derek walked in with a soaking wet waitress, the room went silent.
"Derek?" A tall, sharp-looking woman approached them. This was Jessica Vance, the CTO. She looked at Jaime with open disdain. "Who is this? Did you order catering?"
"This is Jaime," Derek announced. "She's the one who wrote the napkin protocol."
Jessica raised an eyebrow. "The napkin? Derek, you said you had a breakthrough."
Derek flushed, a subtle shade of red creeping up his neck. "I... I said I found a solution. Look, it doesn't matter. Jaime, show her the board."
They led her to a massive whiteboard covered in red ink. It was a mess; they were trying to force a square peg into a round hole. Jaime didn't ask for permission. She picked up a marker.
For the next four hours, Jaime Jenkins wasn't a waitress; she was a maestro. She erased their clunky code. She drew diagrams that linked the drone sensors into a single fluid network. She explained how to use the negative space theory to let the drones guide each other rather than relying on the central server.
"It's like a flock of birds," Jaime explained, her hands covered in marker dust. "A bird doesn't know where the whole flock is going; it only knows where its neighbor is. If you decentralize the collision logic, the latency drops to zero."
The room was dead silent. The engineers were staring at the board. Jessica Vance typed furiously into her terminal. A progress bar on the main screen began to load:
Simulation: Swarm Logic v4.0 Loading...
The bar hit 100%.
Efficiency Rating: 98.4%.
Battery Consumption: -40%.
Status: Optimal.
A cheer erupted in the room. Men in hoodies were high-fiving. Derek slumped into a chair, laughing hysterically. Jessica looked at the screen, then at Jaime with a look that was hard to decipher: it wasn't gratitude; it was calculation.
"You did it," Derek said, standing up and grabbing Jaime's hand. "You actually did it. You saved the company."
Jaime felt a smile tugging at her lips. For the first time in years, she felt seen. She felt valuable. "It works," she said softly.
