Senior Unity Developer specializing in multi-platform games, VR/AR, and multiplayer

Warsaw, Poland9y exp

“Unity/C# developer with 10+ years experience who built a VR disc-golf-style throwing system by translating academic aerodynamics research into a differential-equation-based simulation, then improved “feel” via telemetry-driven input analysis and playtesting. Also created a custom cross-platform multiplayer networking layer (Steam + Oculus/Meta) that cleanly separates gameplay from networking, and recently extended an ASP.NET backend (new endpoints + data refactors) using AI-assisted pair programming to support Bluetooth-based beacon triangulation.”

“Frontend-focused engineer who has delivered an end-to-end React SPA with a .NET 9 backend on Azure, deploying via Azure Container Apps and leveraging zero-downtime deployment slots. Built complex TypeScript UI flows (10-page form with global/partial save and custom validation) using Redux + MUI integrated from Figma, and emphasizes quality with RTL/Vitest plus Selenium automation (~95% coverage) and analytics-driven iteration (Heap, Alida, GTM).”

“Built and deployed a production AI document Q&A (RAG) platform that lets non-technical users query hundreds of PDFs/Word files, cutting search time from hours to seconds. Experienced with scaling retrieval pipelines (chunking, embeddings, vector search, batching/caching) and orchestrating reliable workflows using AWS Step Functions/Airflow with robust retries, monitoring, and fallbacks.”

“Software engineer with a graphic design/marketing background who led a 4-month U.S. Department of State Diplomacy Lab project delivering a proprietary React/Electron + Flask + PostgreSQL scheduling app, including OKTA SSO integration under strict government confidentiality constraints. Also has hands-on production web experience fixing a broken WordPress/Elementor content system by scripting automated recategorization and date corrections.”

“Game/VR simulation developer who built and shipped multiple VR training levels (e.g., nursing and scientific method) at VXR Labs, owning level implementation and backend logic. Experienced in Unreal Engine 5 Blueprints prototyping (including a horde mode) and in designing tightly gated, step-based educational experiences while collaborating closely with educators/subject-matter experts to balance realism with VR feasibility.”

Senior Technical Designer/Engineer specializing in Unreal Engine and AR/VR interactivity

Manchester, NH9y exp

“UE5 Blueprint-focused gameplay developer who shipped a VR rhythm title (Starwave), owning the player-facing star-hit interaction/feel and iterating heavily through playtests without dedicated QA. Also designed a modular tutorial/quest system by decomposing quests into reusable components so writers could assemble content independently, and has experience debugging Unreal Nav Mesh pathing issues that impacted gameplay and load times.”

“Growth marketer with strong end-to-end ownership across messaging, experimentation, and funnel systems for complex products and international expansion. They combine customer research, cross-functional sales/product alignment, and marketing automation to drive measurable outcomes, including 18% MoM customer acquisition growth, 40% lower MQL-to-SQL friction, and a 24% lift in SQL-to-opportunity conversion.”

“CEO & co-founder of Spotlight Creators, a digital platform for visual artists, which they took from idea validation (100 artist interviews) to a live product with 50+ artists and 50+ customers. Drove GTM through hands-on social content across Instagram/YouTube/TikTok, ran local artist spotlight events, and pursued fundraising via cold outreach and acceptance into Launch NY while building skills in pitch decks, financial projections, and ARR modeling.”

“Backend engineer with fintech/AI startup experience who built an Azure serverless, event-driven pipeline for large-scale crypto sentiment analysis and semantic search (OCR/NLP to vector search) and integrated LLM + blockchain data for predictive insights. Demonstrated measurable impact (25% lower retrieval latency, 10% fewer data errors, 15% higher engagement) and has led safe microservices migrations with strong security and reliability practices.”

“Marketing/design creative with experience delivering high-polish brand and web work under complex conditions (including multiple acquisitions), driving measurable growth (2x traffic, +60% organic search, SEO gains across 50+ terms). Also designs product UI in Figma leveraging Material UI patterns and builds modular Instagram video templates in Adobe Premiere/After Effects for scalable content production.”

“Two-time founder and former CTO/CPO who has shipped and operated full-stack products solo, including a real-time community platform (Twitter/Slack-like) with Next.js/TypeScript, WebSockets, Redis, and strong post-launch analytics (PostHog/Sentry). Also built durable multi-step AI-agent workflows using Inngest with state machines, checkpointing, and validation gates, and has hands-on Postgres performance tuning experience validated via EXPLAIN ANALYZE.”

“New-grad backend engineer who built a real-time genome analysis pipeline, replacing a slow batch system with an event-driven distributed architecture in Python/Redis and a React progress dashboard. Reports ~6x improvement and cutting analysis time from days to hours with zero data loss under peak load, emphasizing reliability patterns like retries and idempotency plus API security (JWT/RBAC/HTTPS).”

“Unity/VR developer who shipped the multi-headset project Animotive (primarily on Quest 2/Quest Pro), contributing across design, development, bug fixing, and documentation. Notably tackled a difficult multiplayer problem: synchronizing session restarts for all users and rejoining with identical session data despite 3rd-party networking/API constraints. Also built a mostly solo turn-based strategy prototype for Gamescom 2025 featuring a custom sketch-style full-screen blit shader and pattern-driven AI/UI architecture.”

“Backend/cloud engineer with hands-on ownership of a climate data extraction pipeline (BeautifulSoup + Pandas ETL + CRON) that automated 50k+ monthly data points and removed ~20 hours/week of manual work. Also built a multi-AZ Kubernetes deployment for a Node.js system using Terraform and GitHub Actions (blue-green, rollbacks) and has Kafka/FastAPI experience from a healthcare plan management project.”
