Vetted JavaScript Professionals

“Software engineering capstone contributor who helped kickstart an ambiguous, real-client project ("The Virtual Cowboy") by designing the initial relational database and CRUD foundation, then prioritized and shipped simulation/event functionality that satisfied the client. Also building a personal full-stack Book Notes web app (Node/Express/Postgres) with Google OAuth via Passport and a books API ingestion flow focused on data quality and reliability; has deployment experience with Heroku and PythonAnywhere and is ramping up on AWS.”

“Game developer from a student-led team that shipped a Steam vertical slice (Skyguard), a 3rd-person co-op wave defense shooter. Built core gameplay systems (weapons, movement, wave progression), a UE5 Blueprint/C++ microgame framework, and a gameplay-tag-driven cue system to speed VFX/audio iteration; actively tuned balance using structured playtest feedback and fixed multiple high-impact gameplay bugs.”

“Full-stack engineer with healthcare/ops analytics experience at PatientXpress, shipping a real-time operational dashboard end-to-end (React/TypeScript + Node/Postgres on AWS) that cut manual reporting by 50%. Strong in performance and reliability work—pagination/caching, Postgres indexing/partitioning, Terraform-based AWS provisioning, CI/CD with GitHub Actions, and production incident response with improved monitoring (CloudWatch/Prometheus).”

“Product-focused full-stack engineer with strong performance and reliability instincts: improved production page responsiveness by 15% via lazy loading and render optimization, and built a polished React+TypeScript filtering dashboard with URL-synced state for shareable views. Also designed and operated a Django REST backend with versioning, token auth, structured logging, and API tests, and has handled real production scaling issues through PostgreSQL query-plan analysis and indexing.”

“Backend/full-stack engineer who owned a cloud-native, AWS-based microservices backend for an HRIS product used by ~10,000 users, including onboarding and workflow orchestration. Strong production focus on event-driven architecture, idempotency/retries, observability, and developer-friendly API design (OpenAPI, versioning, JWT), plus hands-on Selenium automation for resilient checkout-style flows.”

“Built and productionized an AI-assisted merchant onboarding automation workflow for Kort Payments, replacing slow manual underwriting document review with structured extraction, cross-document validation, and human-in-the-loop guardrails. Emphasizes reliability via scenario-based testing, repeatability checks, and deep observability (timestamped logs), plus incremental rollout with legacy fallback to prevent regressions.”

“Built and deployed a production Incident Tracking System using Next.js (App Router) + TypeScript with Postgres (Neon) and Prisma, including RBAC (User/Support/Admin), tickets/comments, and audit logging. Uses Zod for schema/type validation and relies on Chrome/React DevTools to debug and refine UI/UX and performance.”

“Open-source JavaScript contributor who diagnosed and fixed a memory leak in an infiniteQueries module using Chrome DevTools, adding useEffect cleanup and weak references to cut memory usage by 32% and close 18+ GitHub issues. Also strengthens quality via unmount-focused tests and CI performance validation, and improves developer adoption by adding real-world infinite scrolling examples to React Query documentation.”

“Backend/data engineer with hands-on production experience building partner-facing Python APIs (FastAPI, Celery, Postgres/Redis) and AWS serverless data platforms (Lambda, SQS, Step Functions, Glue). Emphasizes reliability and governance—JWT tenant-scoped auth, secrets/config hygiene, data-quality quarantine, and incident ownership—plus measurable SQL tuning that eliminated timeouts and stabilized reporting workloads.”

“Growth and partnerships professional in the gaming/creator ecosystem with hands-on experience sourcing and negotiating creator deals, running pilot partnerships, and measuring outcomes via CPA/conversion tracking. Has driven measurable growth through co-marketing and referral loops (e.g., +30% sign-ups and up to +20% revenue in 2 months; +25% leads in 1 month) and improved creator engagement through co-developed content (+40% engagement).”

“Full-stack engineer with strong AWS operations experience who helped replace a long-standing manual logistics reporting process by building a production-grade, event-driven On-Time-Performance rules system. Personally owned the Vue-based rule configuration frontend end-to-end (design collaboration through QA/UAT and post-release support) and measures success via accuracy validation against historical data, reduced manual adjustments/tickets, and system latency/error metrics.”

“Frontend engineer who has led end-to-end delivery of internal and analytics dashboards in React + TypeScript, with a strong emphasis on scalable architecture, disciplined state separation, and performance under real-time data loads. Uses practical profiling (React Profiler/DevTools), virtualization, and feature-flagged rollouts with solid QA and rapid post-launch iteration to keep quality high as products scale.”

“Unity/VR developer who shipped a Meta Quest 2 immersive 360 training experience for Staffordshire Police as a solo programmer, including biometric gaze/reaction tracking and real-time data capture to an HTTP endpoint. Also building a Tomb Raider-like sci-fi adventure demo (Nexus 7) featuring FSM-driven character logic, motion-capture animation, custom controller optimization, and spline-following AI movement.”

“Indie Unity game developer who built a physics-driven fishing mechanic for "Cats Fishing" inspired by RDR2, combining Verlet integration and procedural rod bending to achieve realistic feel without heavy simulation costs. Has prototyped multiplayer systems using multiple networking stacks (PUN/Fusion/UNet/Nakama/Mirror) and adapts features for mobile via gesture controls and minimal UI.”
