Vetted React Professionals

“Engineering leader focused on developer platforms and identity: led a 5-person team building a multi-tenant IAM framework extending Duende IdentityServer, including governance, API standards, and multi-language SDKs. Drove major API architecture improvements by introducing GraphQL alongside REST, cutting client calls from 4 to 1 and reducing payload size by 60% within 6 months, with strong emphasis on stability (semver, E2E tests, feature flags, blue-green deploys).”

“Frontend-focused engineer who built an expense management solution inside Microsoft Teams using React and Formily, modernizing reimbursement workflows that handle ~20,000 approvals per year. Demonstrated practical debugging and reliability improvements (stabilized multi-attachment uploads via event-binding investigation and hash-map-based targeting) and delivered ~30% performance gains by changing data structures, while coordinating stakeholders and team resources during quarter-end pressure.”

“Frontend engineer with experience building backend-driven UI systems (JSON-schema-based rendering) to enable rapid business-driven screen changes, including collaboration across design/backend/product/QA at Ozon Seller Center. Also created an internal npm package that generates TypeScript API clients from OpenAPI docs—initially for one project, later rolled out company-wide with CI testing and version pinning support.”

“Full-stack engineer who led an end-to-end rebuild of a service-agent case management app (React SPA + backend/DB updates) and added Datadog monitoring, improving agent throughput by ~1 case/hour and saving roughly $15K/month. Experienced in incremental legacy modernization (including moving a legacy React frontend toward a Rails-based approach) with heavy unit/E2E testing and strong cross-team stakeholder communication.”

“Serial entrepreneur and software engineer currently ideating a B2B vertical AI SaaS company with seed funding secured, using a custom-built AI agent to generate and vet startup ideas. Previously sold a software product (AskDiagnostic) into physician offices and spun an observed workflow gap into an in-house compounding solution, including a <3-minute dispensing process and supporting software for inventory, compliance, labeling, reorders, billing, and reporting.”

“Frontend engineer who has owned delivery as the only FE developer on a client project (Eltel), stepping into UX/UI and occasionally supporting backend while modernizing a React codebase incrementally. Known for replacing heavy legacy third-party UI libraries with simpler custom React components to improve performance and maintainability, and for working effectively in Scrum teams with strong QA practices (e.g., high unit test coverage and Playwright E2E where possible).”
