Jonathan Terrero

Software Engineer I · OmniFlex Fitness · Naples, FL — Remote

May 2026 – Present

Develop and ship production features across OmniTask (Angular/TypeScript task platform) and OmniTrivia (real-time multiplayer trivia) using TypeScript, Angular, Firebase/Firestore, and Flutter, supporting active users across web and cross-platform mobile clients.
Built batched Firestore write pipeline and typed data-access layer with writeBatch bulk ops, OnPush change detection, and takeUntilDestroyed subscription hygiene, reducing Firestore read/write cost per session by 10% and eliminating a class of subscription-leak concurrency bugs.
Implemented peer code review and PR-based Git/GitHub workflow with typed return contracts, cycle-detection utilities, and DRY shared modules, and collaborated with founders and mobile team to ship OmniTask feature releases and OmniTrivia multiplayer WebSocket rollout on a weekly release cadence.

Robotic Pick-and-Place Arm · Arduino (C/C++), Servo Control, Ultrasonic Sensing, FSM Logic

Spring 2026

Designed and programmed a multi-axis robotic arm for autonomous pick-and-place operation using Arduino Uno, servo motors, and ultrasonic object detection.
Implemented finite state machine control logic to manage motion sequences, sensor feedback, and error handling.
Calibrated joint angles and motion parameters to improve task repeatability and object-handling reliability.

Biomechanical Knee Brace Prototype · Arduino, FSR Sensors, Signal Conditioning, Python

Spring 2025

Designed and prototyped a smart knee brace measuring real-time joint loading using force-sensitive resistors and an Arduino microcontroller.
Built signal-conditioning circuitry and calibration routines converting raw analog readings into quantified force measurements (Newtons), validated against known loads.
Developed Python analytics tools to visualize loading patterns across gait cycles and quantify brace performance, integrating hardware, firmware, and data pipeline end to end.
