Vetted Data Structures Professionals

“Built and organized SQL databases for a grocery pricing update backend and has hands-on experience designing FastAPI/Python APIs with security controls like authentication, RBAC, and strict validation. Also brings research experience identifying real-world failure modes (weather-driven sensor/model inaccuracies in MSE wall corrosion work) and adapting models to improve robustness, plus UI design support on an email-restricted campus hackathon enrollment flow.”

“Robotics engineer who built an educational/research robotic arm end-to-end, including IK/FK math, simulation-based validation, and ROS2 Humble integration with multiple teleoperation inputs (DualSense and Leap Motion). Also optimized a resource-constrained ESP32-S3 wireless maze robot to stream real-time video and sensor data over WiFi using TCP/HTTP with RTOS-based concurrency and binary struct packing.”

“Undergraduate Research Assistant at Virginia Commonwealth University with exposure to autonomous vehicle and UAV platforms in the Open Cyber City lab, assembling and setting up Duckiebots/Duckiedrones. Built introductory ROS 2 Python projects (ping-pong pub/sub and services) and has some experience setting up Docker for Duckietown-based robotics environments.”

“Embedded/IoT-focused builder who has shipped solo projects on ESP32 + FreeRTOS, including a security camera system with a machine-vision pipeline, light-sensor-driven IR control, and Telegram-based animated GIF alerts. Demonstrated real-time debugging skills by resolving race conditions and timing issues via buffer redesign and mutex-based synchronization; no ROS/ROS2 experience yet but open to learning.”

“Built a Smart Resume Screening tool with a React frontend and a Python backend, owning most backend architecture and delivery. Implemented FastAPI endpoints for file upload and NLP/ML inference, created the end-to-end resume classification pipeline, logged predictions to a database for accuracy tracking, and deployed a Dockerized service optimized for low-latency, concurrent processing.”

“Full-stack engineer who built an end-to-end Next.js + Flask admin platform for Ciocca S.p.a., now used daily by 100+ employees for operations and warehouse workflows. Strong in performance tuning (API redesign, query optimization), secure RBAC, background job offloading, and integrating AI-powered internal tools that automate reporting and reduce manual workload.”

“Unity AR/VR developer with experience delivering multiple projects using Vuforia, Unity AR Foundation, and Niantic Lightship, including VR terrain generation from GIS data learned and implemented on a tight timeline. Built a personal Unity "LLM testing tool" integrating ChatGPT, Gemini, Claude, Mistral, and DeepSeek into NPC characters with customizable multi-party conversation behavior for comparative evaluation.”

“Hands-on LLM/agentic workflow practitioner who focuses on moving prototypes into production by improving data quality, preprocessing, and validation, and by testing against real user inputs. Experienced troubleshooting LLM issues in real time during live tests and supporting adoption through developer demos and sales-partnered technical explanations that address customer reliability concerns.”

“Game designer/developer who built and tuned an RPG prototype economy and progression loop end-to-end (two-currency system, exploration-driven rewards, and difficulty tiers based on exploration). Uses quick playtesting-driven iteration plus basic quantitative modeling (minimum economy to clear) and implemented probabilistic drop systems to prevent runaway rewards. Based in Buenos Aires and open to remote or local on-site work.”
