Vetted System Design Professionals

“Unreal Engine generalist (7 years) with hands-on ownership of end-to-end gameplay systems in real-time 3D C++ and UE5, spanning technical level design, animation/locomotion features, and multiplayer replication. Worked on a shipped Steam title ("Peak 53") implementing replicated systems like prone, scope, and ladder, and has also built MMORPG time/weather systems and a projectile/rocket launcher feature for a demo (Meta Island).”

“Casual mobile game designer (Unity-focused) with a psychology background who uses player research and BI analytics to drive retention and revenue. Led major difficulty rebalancing across thousands of levels (reported +5–10% retention lift) and partnered with engineering/art to create a parameter-driven level generation pipeline that quadrupled chapter output and increased release cadence.”

“Robotics lead engineer (PhD/agriculture research context) who built and iterated a three-unit, wirelessly coordinated greenhouse data-collection robot—solving real-world alignment and comms reliability issues by redesigning the rail/gear system and moving from RF to ESP Wi-Fi with MAC-addressed control. Strong embedded C/C++ background with full-stack robot control implemented from scratch; beginning exposure to ROS 2 via an upcoming field deployment.”

“Unity VR developer with ~4 years of experience who has shipped an app to the Meta Quest Store. Notably worked on a challenging VR project integrating live point cloud data, focusing on bandwidth/latency, optimization, and compression to keep performance smooth in-headset.”

“Frontend engineer with freelance and Techtank Toronto experience leading React + TypeScript products end-to-end (UX through implementation). Emphasizes scalable component architecture, accessibility, and performance, and has a pragmatic approach to state management (Redux/Context + React Query) and fast-paced shipping with feature flags and staged rollouts.”

“AI/backend engineer who has built and scaled production LLM-powered SaaS features (document assistant + compliance review agent) on a Node.js/TypeScript + Postgres/Redis stack deployed to GCP Kubernetes. Demonstrates strong production reliability chops—async queueing, autoscaling, observability, and database tuning—with quantified wins (p95 latency -60%, query 4s to <200ms) and robust AI guardrails (strict RAG, schema validation, citations, HITL).”

“Product/UX designer with strong front-end engineering capability who builds and deploys functional prototypes (React, Tailwind, Vercel) and bridges design-to-code via tokenized design systems. Has designed an AI-driven e-commerce fit/3D scanning experience (progressive disclosure, stress-map feedback) and is currently digitizing mass-casualty incident triage with haptics and spatially consistent, non-visual interactions to reduce medic distraction and error under extreme stress.”

“Backend/data engineer with hands-on production experience building a FastAPI Python service on AWS for real-time AI workflows (Postgres/Redis, containers behind API Gateway) with strong reliability practices (JWT auth, timeouts/retries, health checks). Has delivered AWS infrastructure using Terraform + GitHub Actions across environments, built Glue ETL pipelines into Snowflake with idempotent recovery, and modernized legacy batch workflows via parallel-run parity validation and phased cutovers.”

“Early-career full-stack engineer who has not yet shipped a professional customer-facing product but has built sophisticated AI-driven systems in personal/academic work, including a multi-tenant AI knowledge base (async ingestion, pgvector semantic search, SSE real-time updates, knowledge graphs) and an AI-powered code review assistant designed to process thousands of jobs via Redis/BullMQ.”
