Senior Unity Developer specializing in mobile and VR/PC games

Warsaw, Poland7y exp

“Unity gameplay engineer from Moonactive who rewrote the gameplay engine for ZenMatch, maintaining two engines in parallel via a separation layer to improve robustness/scalability and make new content easier to ship. Also implemented multiplayer for a client prototype using the Onion networking framework and is familiar with Photon Fusion concepts.”

“Backend engineer with experience spanning regulated financial systems at Oracle Financial Services and early-stage product building at Apli.ai. Has owned production onboarding infrastructure end-to-end, improved reliability through strong observability and incident response, and also built AI-backed backend workflows using AWS, Bedrock, and RAG.”

“Unity gameplay developer who led implementation of an airport scene for Duplo Town (children’s physics/exploration game), adding multiple unspecced interactions that significantly increased polish and playfulness and delighted testers/clients. Principal/lead-level engineer with strong sprint planning and impact-vs-effort prioritization, plus experience designing asynchronous client-server interactions and state management (aware of Photon-style real-time multiplayer sync).”

“Currently working in CoRAL Lab, built and deployed IntegrityShield—a document-layer PDF watermarking system that keeps assessments visually identical while disrupting LLM-based solving; validated in a real classroom where it helped catch 12 AI-cheating cases. Also built MALDOC, a modular red-teaming platform for document-processing AI agents using LangGraph to run reproducible, deterministic adversarial trials across OCR/text/vision routes.”

Executive technology leader specializing in cloud, AI, video, and embedded systems

San Francisco Bay Area, CA32y exp

“Serial startup founder with multiple prior ventures that raised capital, now building an AI supervision product focused on child safety in online gaming. Has repeatedly operated in new technology categories such as WiFi, video over IP, cloud gaming, and AI supervision, and approaches validation through customer interviews, industry research, and bootstrapped market proof.”

“Frontend engineer focused on marketing and analytics products, including a real-time multi-touch attribution dashboard. Uses Next.js (SSR/ISR) with React/TypeScript and Tailwind, and emphasizes quality at scale via automated testing, CI/CD (GitHub Actions), feature-flagged staged rollouts, and Mixpanel-driven iteration. Experienced modern state management patterns (React Query + Zustand) and performance tuning (code-splitting, dynamic imports, lazy loading).”

“Unity game developer who built a "constraint-driven match resolution" card-game system that encouraged players to think 1–2 moves ahead while keeping interactions as simple as UNO-style matching; reported longer player sessions and positive feedback. Has used Photon to implement most online features in games and leverages AI tools for code writing to boost productivity.”
