EV ChitChat was built so your Tesla answers out loud, without opening an app.
Voice Assistant for TeslaYour Tesla, by voice. Ask Alexa how charged the car is, how far it can go, whether it is locked, plugged in, or what the cabin temperature is, and get an answer in one breath. Charging time, tire pressure, charge limit, software updates, and odometer too. Every connection starts with the owner through Tesla's official sign-in, and every answer comes from a single read. Tesla credentials are encrypted and server-only, never reaching Alexa or the browser. Reading the car is free. EV ChitChat Plus adds the commands that act on it: cabin climate, maximum defrost, and road trip charging with a command to set it back to daily, signed by an isolated service that holds no user data. It sends no driving or locking commands. Independent software, not affiliated with Tesla or Amazon.
Live on the Alexa Skill Store for US Tesla owners. Reading the car is free, and EV ChitChat Plus adds climate and charging commands for $2.99. Owner-authorized only, no driving or locking commands, and a sleeping car stays asleep.

Native Mobile Proof of Concept
Native iOS and Android proof of concept for a patent-pending concept in the audio space, blending hardware behavior with software control. Delivered from feasibility study through working builds on both platforms, plus the technical brief and investor materials behind them.
“Roman is a passionate app developer, and it's clear that he takes the time to fully understand the technical problem before jumping into a solution. His technical expertise speaks for itself, but what impressed me most was his ability to challenge my thinking, identify blind spots I hadn't considered, and help reinforce and evolve my original idea into something even stronger. I also appreciate the unique perspective he brings from his Air Force and Space Force acquisitions background. He combines that experience with his technical expertise in a way that makes him a true professional and someone I can trust with my future app development needs. I'm excited to continue working with Roman and look forward to having him help me turn my vision into a reality.”
