Vetted Performance Optimization Professionals

“UE5 gameplay/tech designer focused on VR and performance, with shipped systems spanning networked energy-driven Niagara VFX for a mobile VR live-concert MMO and an end-to-end performer avatar builder supporting editor/runtime and JSON-serialized UGC workflows. Known for deep profiling/debugging (Unreal Insights, Niagara CPU vs GPU emitter behavior) and for refactoring/optimizing animation and rendering across PC and mobile VR constraints.”

“GenAI builder and technical lead with ~2 years of hands-on production experience, including GENIE (a GenAI sandbox for ~44,000 Massachusetts public-sector employees) and A-IEP, a multilingual platform helping parents understand complex IEP documents (cut processing from ~15 minutes to ~2 and used by 1,000+ parents). Strong in RAG/agentic architectures, AWS serverless + Step Functions orchestration, and rigorous evaluation/guardrails for reliable real-world deployments.”

“Robotics software engineer focused on production-grade autonomous mobile robot (AMR) navigation in warehouse-style environments, with deep hands-on ROS2/ROS Noetic experience across SLAM, AMCL/NDT LiDAR localization, and Nav2 integration. Strong in real-time debugging and performance tuning using rosbag-driven regression workflows, plus containerized deployment (Docker/Compose) and distributed robot/edge-device communication via MQTT/REST.”

“Backend/data engineer with hands-on production experience building Python (FastAPI/Flask) data enrichment services secured with Okta OAuth2 and monitored via Splunk/Dynatrace. Has delivered AWS event-driven and data-migration solutions (Lambda + Kafka to EKS; Glue from on-prem Oracle to S3/data lake) and modernized Informatica match/merge logic to cloud services using parallel-run parity validation and stakeholder sign-off.”

“Frontend engineer who built a live sports games hub end-to-end: ingesting and normalizing data from 4 external APIs, populating a high-volume live table, and delivering a real-time WebSocket-driven React/TypeScript dashboard. Strong on scalable architecture (SOLID, layered design, queues), performance/load testing with Docker, and startup-style ownership across code review, QA, and staged rollouts to web and app stores.”

“ML engineer with hands-on experience taking a Gaussian Process Regression-based intelligent survey timing system from build to real-world deployment, including a 3-week RCT on 120 participants and measurable improvements (15% response rate, 23% data quality). Also served as a key technical resource at CData for customer-facing demos and debugging hundreds of production issues, bridging engineering with Sales and Customer Success.”

“Frontend engineer who led end-to-end delivery of a Vite/React/GraphQL/MUI SPA with feature-based, layered architecture and strong quality gates (TypeScript strict, CI, testing, a11y). Built a large analytics dashboard using microfrontends and multiple state management approaches, including integrating with a legacy PHP host via window-object communication, and managed safe rollouts with LaunchDarkly plus Datadog usage/session-replay monitoring.”

“Software engineer with hands-on experience building data-intensive and 3D-processing web applications (React/Next.js/TypeScript + Node.js). Has worked in microservices using RabbitMQ for event-driven workflows and built an internal ops/engineering dashboard to monitor pipeline jobs, surface logs, and manage retries—improving visibility and reducing on-call/debug time.”

“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.”

“Full-stack engineer who has shipped end-to-end, customer-facing features in an education/student-population context, including an authorized incident-reporting workflow with RBAC and a PostgreSQL-backed data model. Has 0→1 React+TypeScript/Redux product experience (CTO at Jiffur) and hands-on production operations with CI/CD (Azure Pipelines/GitHub Actions), including resolving a real CPU-saturation outage via operational mitigation and scaling changes.”

“Frontend engineer (Capgemini experience) who has led products end-to-end and improved existing codebases for scalability and performance. Built complex React + TypeScript dashboards with real-time, multi-API data and stabilized them via centralized data handling, strict typing/validation, and performance techniques like debouncing/memoization. Emphasizes practical standards, incremental refactoring, and tight collaboration with design/product and QA to ship reliably under deadlines.”

“Unity developer from the Naer project who built a natural-feeling VR wrist-flick gesture mechanic for teleport/push/pull interactions, validated through telemetry, low-FPS simulation, and diverse user testing with modular ScriptableObject tuning. Also handled Photon PUN 2 networking bug fixes (mid-air item state issues) and RPC optimizations while integrating AI tools (Claude/Gemini/ChatGPT) into planning and implementation.”

“Unity game developer focused on gameplay AI and combat feel; reverse-engineered and recreated Devil May Cry-style enemy behavior using an attacker/bystander system constrained by the camera frustum, including custom math to solve circle–frustum intersections. Has shipped/worked on multiplayer projects using Photon Fusion and Unity Netcode for GameObjects, with practical experience making state/RPC synchronization decisions.”

“Backend/platform engineer with payments and insurance domain experience (Cognizant), owning high-volume production systems end-to-end. Shipped a Spring Boot payment tokenization service with strong observability and phased migration that cut transaction latency ~30% and improved payment efficiency ~25%. Also productionized an ML-driven financial health/risk analytics pipeline with near real-time dashboards across 70+ schools, emphasizing interpretability, data quality, and drift monitoring.”

“Full-stack engineer who builds and scales customer-facing and internal AI products end-to-end (React/TypeScript/FastAPI/MongoDB) with strong product instrumentation and rapid MVP iteration. Built an AI-powered code review assistant adopted across teams and integrated into CI/CD, reducing manual review time by 30%+, and has hands-on experience with LLM retrieval/reasoning systems (LangChain + FAISS) and microservices scaling using RabbitMQ, Docker, and AWS.”
