Front end (one or more): React / or Angular / or Vue.js.

Back end (one or more): Node.js / or Python (FastAPI/Django/Flask).

Strong proficiency in JavaScript/TypeScript, HTML5, and CSS3.

Experience designing and consuming REST or GraphQL APIs.

Solid with relational databases (PostgreSQL/MySQL) and ORMs; familiarity with Redis or DynamoDB is a plus.

Comfortable with Git-based workflows and pull requests.

Performance-minded: profiling, caching, pagination, bundle splitting, DB indexing.

Security basics: auth (OAuth2/JWT), input validation, OWASP awareness.

Excellent problem-solving aptitude and strong communication skills.

Ability to work cross-functionally in agile teams and mentor peers.

Next.js (App Router), TanStack Query/RTK Query on the front end.

Experience with Client-Side ML Libraries

TensorFlow.js for in-browser inference/training.

ONNX Runtime Web/onnx.js for standardized model runtimes in the browser.

Data Handling & Formatting: Work fluently with JSON; structure payloads to match model input/output contracts; visualize results clearly (charts, overlays, timelines).

Awareness of model limitations: account for inference latency; use loading/skeleton states, timeouts, and graceful fallbacks.

Experience with data visualization (Recharts/Chart.js/Plotly/D3).

Build reusable UI components and front-end features with React / Angular / Vue.

Design, implement, and maintain back-end services using Node.js / Python / Java.

Model data, write efficient queries, and tune performance (indexes, caching).

Integration ML/AI endpoints (REST/GraphQL) asynchronously (fetch/axios), handle retries, timeouts, and error states gracefully.

Ensure apps are responsive, accessible (a11y), and cross-browser compatible.

Implement authentication/authorization, input validation, and secure coding practices.

Add observability: meaningful logs, metrics, traces; participate in on-call/triage as needed.

Write and maintain unit/integration/e2e tests; participate in code reviews.

Collaborate in agile ceremonies—refinement, planning, stand-ups, and retrospectives.
