Vetted Object-Oriented Programming (OOP) Professionals

“Built and deployed a production LLM-powered document Q&A system using a strict RAG pipeline (LangChain-style orchestration + FAISS) to help users query large internal document sets. Demonstrates strong reliability focus through hallucination mitigation, curated offline evaluation with grounding checks, and production monitoring (latency/fallback rates) plus stakeholder alignment via demos and business metrics.”

“Unity/VR gameplay engineer who has shipped full games and built a robust coin economy + massive gear customization system (over a million combinations) backed by a cloud service. Notably discovered and fixed a severe backend security flaw by adding proper authentication (security key + OAuth2), and has hands-on VR performance optimization experience (OVR Metrics, LOD/mipmaps, imposters) plus multiplayer sports sync design using Photon PUN2.”

“Lead Unity developer who shipped two public-facing VR projects (Aberwla full release and Cognetic demo) end-to-end to the Meta Quest Store at Animated Technologies, including optimization and VRC compliance. Currently building solo first-person horror/ghost-hunting projects and aiming to ship a small-scope atmospheric title to Steam to broaden platform shipping experience.”

“Robotics software engineer with hands-on hardware integration who built an AI-enabled smart dog door using a Raspberry Pi, camera-based recognition (DeepFace adapted for dogs), and stepper motor control (TB6600/NEMA 17). Experienced in ROS/ROS 2 across perception-to-controls, rigorous bag-driven debugging of SLAM/navigation issues, and deploying robot software with simulation-in-the-loop testing plus Docker/Kubernetes CI/CD.”

“Game-focused QA tester with a developer background who routinely validates builds in player-like environments (including VMs), documents test coverage rigorously, and provides high-signal bug reports with reproducible steps and video evidence. Has partnered closely with designers and engineers on issues like level-loading resource management and prioritizes defects based on player progression and immersion impact; has not shipped a AAA title.”

“Built and owned an end-to-end Python/Postgres job-tracker backend that scrapes job postings (including LinkedIn) using Selenium-driven real-browser automation, with deduplication and data-quality filtering. Has practical experience migrating deployments from DigitalOcean to Vercel and emphasizes documentation, roadmapping, and testing as part of an iterative delivery cycle.”

“Backend engineer who built a production retrieval-augmented narrative analysis platform for 100-page screenplays using a Node/Express orchestrator and a Python/FastAPI AI engine, including a key redesign from disk-based uploads to in-memory streaming to eliminate Windows file-lock failures. Also led a refactor of a municipal vehicle tracking system into a C-based distributed engine handling 4M+ daily packets with 99.99% data integrity and automation that reduced manual ops by 50%.”

“Backend engineer who rebuilt and refactored high-traffic systems at Phenom using Java/Spring Boot/Play and also designs Python/FastAPI services. Focused on measurable reliability and performance gains through DB/query optimization, async processing, and strong observability, with disciplined rollout practices (feature flags, parallel runs, rollback) and security patterns including token auth and row-level security.”

“Unity developer with ~5 years of professional experience who served as the main developer on a shipped Meta Quest VR game (Smash Therapy), handling most of the code and tackling key VR challenges like UI/UX and standalone performance optimization. Also builds AI-driven gameplay systems (e.g., minimax-based unbeatable tic-tac-toe) and leverages AI assistants to speed up routine implementation and brainstorming.”

“Unity VR developer with 3 years of experience shipping games for Meta Quest, focused on gameplay event handling and animation control. Prefers structured production environments and on-site, 9-to-5 work; notes multiplayer development as a more challenging area.”

“Unity generalist with VR-focused optimization experience who replaced a bloated third-party IK/rigging plugin by building a custom DOTS/Burst multithreaded system, reporting ~200% performance gains and a noticeably smoother VR experience. Has multiplayer experience with Unity Netcode (and some Photon Fusion exposure) and uses AI tooling (Rider AI) to speed up refactoring and documentation.”
