“VFX generalist with shipped mobile game experience (Caveworld) who builds performant 2D sprite-based effects end-to-end—from hand-painted Photoshop textures through optimized materials and particle systems. Demonstrates strong real-time optimization practices (overdraw analysis, texture combining, mesh reduction, culling) and a clear understanding of mobile/Switch rendering constraints.”

“Unity/C# game developer who served as CEO and lead developer on the Unity 2D pixel RPG "Rum Runner's Revenge," owning technical direction, modular architecture, and core gameplay systems; the project earned a TIGA award nomination. Also shipped a commercial Unreal Engine title and built an adaptive difficulty system using player performance metrics, leveraging AI tools for rapid prototyping and debugging.”

“Unity developer with hands-on Meta Quest mixed reality experience, building an AI-companion app with a real-time 3D avatar and local LLM backend using Whisper + GPT-SoVITS for STT/TTS. Also the primary programmer behind a Steam-published peer-to-peer co-op horror game built in Unity with Mirror networking.”

“Performance marketer managing a high-spend B2B SaaS account ($70K–$100K/month) across Meta, LinkedIn, and Google Ads with a full-funnel approach focused on demo/trial quality tied to revenue. Known for disciplined single-variable testing and signal-quality-based budget allocation, delivering a 28% CPA reduction while scaling spend and maintaining conversion efficiency.”

“Robotics software engineer with deep ROS/ROS 2 experience spanning both simulation and real hardware. Led a Master’s thesis building a decentralized multi-robot control stack in ROS 2 (Isaac Sim + Nova Carter), implementing nonlinear MPC (casADI) and RRT* planning with SLAM/3D LiDAR, and tackled tricky frame-convention integration issues. Previously built an autonomous quadruped for first responders (PACRR), integrating LiDAR/RGB-D/IMU sensors and tuning navigation behavior through iterative field testing.”

“IT Analyst/research background with hands-on experience deploying and hardening a multi-agent AI support/triage system (ticket ingestion + knowledge-base retrieval) with strong emphasis on reliability and observability. Has debugged real production issues spanning backend services and network latency (sync failures/partial writes) and is comfortable in Linux environments; also has academic exposure to robotics simulation and ROS2.”

“Unity VR/AR developer with 10 years of experience who built a complex multiplayer online Jenga game from scratch, including VOIP and a custom physics synchronization approach to make heavy physics work smoothly online. Has also delivered VR simulation experiences for an educational institution using drone-recorded 360 video placed into a virtual cockpit flight experience (deployed directly to Quest headsets, though not launched on the Quest store).”

“Unity developer who has shipped VR games on Meta Quest/Oculus Go and demonstrates strong performance engineering for constrained hardware (multithreading, Unity Job System, Jump Point Search). Has built multiple games largely solo (e.g., Tap & Conquer), handling UI/flow, core gameplay, and save systems, and uses AI to speed up build/test/backup automation via shell scripting.”

“Audio editor/mixer with ~10 years in radio plus video production experience, using Sound Forge, Adobe Audition, Pro Tools, and Sony Vegas. Has delivered tightly timed event intros (120s) blending grandeur music, foley-style SFX, and VO processing, and has reworked radio commercials creatively (e.g., soap spot) to improve client impact using targeted sound design and VO.”

“Solo game developer for 3+ years seeking to join a team environment. Built a futuristic "soundwave" gun feature by enhancing weapon detail/rigging in Blender and implementing responsive moving parts and VFX in Unity; observed higher engagement in Poki playtest videos (~15% more time spent). Has implemented multiplayer in small games using Unity Multiplayer Netcode and Mirror, and uses ChatGPT to speed up coding and webgame debugging.”

“Performance marketer experienced managing $50K+/month+ budgets across major DSPs and social/video platforms (TTD, DV360, Meta, Amazon, LinkedIn, TikTok, Reddit, CTV/streaming). Highlighted a multi-channel campaign for a Chicago architectural boat tour that used pixel-based purchase tracking to achieve an 8:1 ROAS and drive millions in attributed sales, with a disciplined testing and optimization cadence.”

“Unity gameplay programmer with practical performance optimization experience (object pooling for shooting mechanics) and extensive Photon-based multiplayer work across diverse genres including shooters, sports, and board games (e.g., ludo, chess, air hockey, snakes and ladders). Uses AI tools to accelerate development, including generating and implementing multiple effects programmatically in a single day under deadline pressure.”

“Backend/full-stack engineer with experience building customer-facing contact-center automation (agent assignment) and internal editorial/data operations APIs for life-sciences ontology management. Strong in microservices and event-driven systems (Spring Boot + Kafka), third-party integrations (Genesys/Five9), and pragmatic iteration via MVP scoping, tight stakeholder demos, and observability-focused reliability.”

“Game designer/developer building systems-heavy gameplay in Unreal Engine 5 using Blueprints, including an RPG narrative/quest framework (dialogue + quest segmentation, HUD/logbook) and an in-progress FPS with ammo and perk-driven playstyles (e.g., tech hacking routes). Demonstrates strong playtest-driven iteration, including major narrative restructuring for clarity and cutting an inventory system after repeated negative feedback.”

“Robotics/embedded developer with hands-on ROS 2 and micro-ROS experience on ESP32, building a remote-controlled high-power LED system. Worked across power distribution (buck-boost constant 30V), sensor calibration with real-time data checks, and long-range WiFi connectivity using an omnidirectional antenna achieving 100m+ coverage.”

“Console game QA tester with part-time experience at GP Outsourcing Sdn Bhd testing multi-platform ports (PS4/Xbox One/Switch/PS5), including Resident Evil 6 and River City titles. Notable for extremely detailed, protocol-driven bug capture using a Phantom v1610 high-speed camera and for identifying timing/performance issues (e.g., a cross-platform soft-lock and a 125ms multiplayer delay) and escalating them as critical to get fixed before release.”

“Builder with hands-on security hygiene experience from developing a helpdesk portal handling sensitive payment/invoice data, focusing on RBAC, least-privilege integrations (QuickBooks/Atera), and tightening API authorization to prevent cross-account access. Also built personal projects integrating Twilio/Callkeep/Supabase/OpenAI with strong key management and defensive handling of real-world API/network failure modes; holds an ISC2 certification and is actively deepening cloud security skills.”

“Mobile QA tester with hands-on manual testing experience (functional flows, UI/UX checks) and disciplined documentation/bug tracking in JIRA. While new to console testing and TRC/XR/LOT certification requirements, they describe a concrete ramp-up plan (study guidelines, review standards, shadow experienced testers) and emphasize clear defect communication and deadline-driven prioritization.”

“Game designer/technical designer with hands-on Unreal Engine 5 Blueprint implementation, specializing in horde/wave modes, spawn systems, and live-service progression/economy. Shipped a limited-time Horde Event Mode under a ~6-week constraint by reusing existing content and focusing on systemic tuning (pacing, spawn budgeting, difficulty curves), reporting improved engagement/retention and reduced early drop-off.”
