Vetted C# Professionals

“Unity/Meta Quest programmer with 2 years of experience shipping two award-winning VR games (Spatial Ops and Twenty Guys) now live on the Meta Store with 4.8+ ratings. Contributed major gameplay/tech systems including co-location, an in-game map editor, and active ragdoll/physics interactions, and has also built Unity apps largely solo spanning rendering, shaders, serialization, VFX, and async/state management.”

“Built a production LLM-powered clinical note summarization and retrieval system that structures patient/provider/payer discussions into standardized outputs (symptoms, treatments, clinical codes, and prior-auth decisions) and stores notes as embeddings for hybrid search and proactive prior-authorization prediction. Experienced with LangChain/LangGraph orchestration, RAG, and grounding against medical code databases, and has communicated model feasibility/limitations to business stakeholders (Virtusa/Comcast).”

“JavaScript engineer with open-source library contribution experience, including diagnosing a validation-related bug, shipping a tested fix, and improving documentation with practical examples and edge-case guidance to reduce repeated community questions. Emphasizes profiling-driven performance work, small safe refactors, and proactive ownership in fast-moving, unstructured teams.”

“Backend/LLM engineer who ships production internal tooling end-to-end: automated data-request processing with monitoring-driven improvements (better error diagnostics and lower latency via query/index tuning). Also built a RAG-based internal Q&A system over company docs and operational logs with guardrails (similarity thresholds, fallbacks, response limits) and an eval loop using real user queries and human review to drive prompt/retrieval changes.”

“Frontend engineer who led an end-to-end responsive enterprise banking platform in a regulated environment, emphasizing domain-based architecture, strict TypeScript contracts, and explicit state-machine-like flow modeling. Implemented Redux + React Query state separation, claimed 100% Jest coverage, and improved Jenkins CI/CD to speed deployments ~30% while also resolving major re-render performance bottlenecks.”

“Unity VR developer with long-standing experience shipping on the Oculus/Meta Quest ecosystem (dating back to before the Facebook acquisition). Recently drove a high-stakes OpenXR migration for a live service app using release branches, QA, feature flags, and staged rollouts. On Border Bots VR, owned the robot character editor and major performance work, including a manual scene optimizer to reduce overdraw and enable higher-fidelity set pieces.”

“Unity developer with shipped Meta Quest experience (including Meta Quest for Business) and a recently released Steam demo for a self-built simulation game, Skyfields: Gooey Garden. Built system-heavy gameplay including procedural creature generation and a genetics/breeding mutation system, and has hands-on experience with multiplayer/networking stacks (Photon, Unity Netcode, Relay) while using sprint-based user feedback loops to drive iteration.”

“Backend engineer with Paycom experience who deployed a TypeScript web app on AWS and is re-architecting Stripe webhook handling using Kafka for durable, high-throughput asynchronous processing. Also delivered a freelance Python solution for a hospital that ingested sensor API data, normalized inconsistent readings, generated reports, and sent threshold-based email alerts while collaborating directly with hospital staff.”

“Unity gameplay developer who implemented complex, role-based unit movement around a central arena target (including altitude separation and animation-synced, math-driven motion) to create more unpredictable and engaging gameplay. Over the last 3 years has focused on REST API work, including building a robust, switchable communication layer (HttpClient/UnityWebRequest) with cancellation, retries, and error handling; has prior experience with deprecated Photon PUN.”

“Backend engineer who owned and shipped a campaign analytics API (FastAPI/Postgres/Redis/Celery) with ingestion from Instagram/YouTube, JWT auth, tests, and Docker deployment; improved performance from >1s to <150ms using precomputed aggregates and composite indexes. Experienced with Kubernetes GitOps using GitHub Actions + ArgoCD (zero-downtime rollouts, one-click rollbacks), Prometheus/Grafana observability, hybrid cloud-to-on-prem migrations, and real-time notification streaming via Redis Pub/Sub + WebSockets.”
