Overview

Fullstack web developer (middle-level) specializing in MERN and AI-driven web tooling. The strongest proven skill is building backend-integrated features such as AI website generation and payments, evidenced by server/controllers/website.controllers.js and billing.controller.js (Stripe checkout and webhook handling). Public code shows focused frontend polish and integrations but lacks systematic evidence of automated tests, accessibility auditing, and measured performance optimization.

Windows Server

Middle Backend Developer Confidence: Medium API Engineer

A backend API engineer (approx middle level) focused on Node.js/Express services with a strength in integrating AI endpoints and payment flows. The strongest proven skill is building REST controllers that wire AI generation and payment logic, as seen in website.controllers.js and stripe.Webhook.controller.js. The codebase lacks advanced resilience, formal input validation, migrations, structured observability and production-grade security hardening.

API Design

3/10

How well APIs are designed

Reasonable REST API structure with clear routes, error handling and some idempotency/credit checks, but lacks formal versioning, input validation layers, idempotency keys and comprehensive error contract design.

Evidence

GENAIwebsitebuilder/server/index.js: route wiring for /api/auth, /api/user, /api/website, /api/billing

GENAIwebsitebuilder/server/controllers/website.controllers.js: generateWebsite, changes endpoints with credit checks and status codes

GENAIwebsitebuilder/server/controllers/auth.controller.js: googleAuth sets httpOnly cookie and returns user

Data Layer & Database

3/10

Working with databases

Uses Mongoose effectively (lean, populate, insertMany, atomic $inc update) showing practical data-layer decisions, but no migration history, transaction use, or advanced query tuning is present.

Evidence

GENAIwebsitebuilder/server/controllers/website.controllers.js: .find(...).sort(...).select(...).lean() usage in userWebsites

GENAIwebsitebuilder/server/controllers/stripe.Webhook.controller.js: User.findOneAndUpdate with $inc for credits

interviewprepGenai/backend/controllers/sessionController.js: Promise.all and insert/populate patterns for sessions and questions

Scalability & Performance

2/10

Handling load and speed

Some performance-aware choices (use of .lean() and selective fields, minimal cache-control header) but overall no caching strategy, no rate limiting, no queueing or connection pooling tuning.

Evidence

GENAIwebsitebuilder/server/controllers/website.controllers.js: .lean() and .select(...) to reduce payload

GENAIwebsitebuilder/server/controllers/website.controllers.js: deployWebsite sets Cache-Control: no-store

System Architecture

3/10

Overall system structure

Clear modular structure with controllers, routes, middleware and config files, demonstrating conventional service separation, but no evidence of multi-service contracts, service decomposition rationale or advanced config/secret management beyond dotenv.

Evidence

GENAIwebsitebuilder/server/index.js: imports and mounts authRouter, userRouter, websiteRouter, billingRouter

GENAIwebsitebuilder/server/middlewares/isAuth.js: presence of auth middleware (imported by routes)

GENAIwebsitebuilder/server/config/stripe.js and server/config/db.js: separation of external service and DB setup

Security & Auth

3/10

Protecting data and access

Basic auth and security practices are present (JWT cookies, bcrypt hashing, Stripe webhook signature verification), but there are insecure defaults and missing hardening such as short token lifetimes, input validation, CSRF protections and secrets lifecycle management.

Evidence

GENAIwebsitebuilder/server/controllers/auth.controller.js: jwt.sign and cookie settings for token

GENAIwebsitebuilder/server/controllers/stripe.Webhook.controller.js: stripe.webhooks.constructEvent signature verification

interviewprepGenai/backend/controllers/authController.js: bcrypt hashing and JWT generation

Reliability & Observability

2/10

Stability and monitoring

Basic reliability patterns exist (try/catch, error responses, console logging), but there is little observability, no structured logging, no metrics, no retry/backoff patterns and no graceful shutdown handling.

Evidence

GENAIwebsitebuilder/server/controllers/website.controllers.js: try/catch and console.error usage in endpoints

interviewprepGenai/backend/controllers/aiController.js: try/catch around AI calls with error responses

Recommendations

Build RESTful services that integrate third-party APIs (AI models, Stripe) and simple credit/payment systems.
Develop CRUD-driven SaaS features with MongoDB/Mongoose including lean queries, populate and atomic updates.
Implement and harden webhooks and auth middleware, including signature verification, cookie/JWT best practices and input validation.
Instrument services with structured logging, metrics and basic retries/backoff for external calls.

Middle Frontend Developer Confidence: Medium Fullstack

UI Component Architecture

3/10

How interface parts are built

Modular component structure with reusable pieces is present but mostly conventional portfolio components and small custom hooks; composition is used but there is limited evidence of a deliberate design-system or advanced component patterns.

Evidence

Portfolio/src/components/resume/Skills.js

Portfolio/src/components/projects/ProjectCardData.js

Portfolio/src/components/features/CardData.js

Responsive & Cross-browser

4/10

Works on all screens and browsers

Responsive design is actively used via Tailwind with custom breakpoints and responsive classes; custom CSS utilities and scrollbar/animation utilities indicate attention to cross-device styling.

Evidence

Portfolio/tailwind.config.js

interview-prep-ai/src/index.css

Portfolio/src/components/resume/Skills.js

Performance Optimization

3/10

Speed of the interface

Some server-side performance awareness (use of .lean()), and Vite config tweaks exist, but there is no measured/perf-audited optimization, bundle analysis, or advanced client-side strategies (virtualization/lazy-loading) shown.

Evidence

GENAIwebsitebuilder/server/controllers/website.controllers.js - .lean() usage in userWebsites

GENAIwebsitebuilder/client/vite.config.js

Accessibility & Semantics

2/10

Usable for everyone

Basic semantic HTML and form labels are used, but there is little evidence of ARIA on custom widgets, focus management, keyboard handling, automated a11y checks, or CI a11y tooling.

Evidence

Portfolio/src/components/contact/Contact.js

Portfolio/src/components/projects/ProjectCardData.js

State Management & Data Flow

4/10

Managing data in the app

Server-client data flows show validation, auth checks, credit accounting, retry/parse logic for AI outputs and reasonable error handling; frontend state flows are basic (local state, Redux present) but show practical discipline rather than advanced server-cache patterns.

Evidence

GENAIwebsitebuilder/server/controllers/website.controllers.js - generateWebsite and changes (retry + parse + credit deduction)

Portfolio/src/components/contact/Contact.js - form validation and isSubmitting state

GENAIwebsitebuilder/client/src/redux/store.js (redux usage present)

UX & Visual Polish

4/10

Look and feel quality

Good visual polish for portfolio UI with animations, transitions and clear loading/error/feedback for user actions; UX patterns are present but limited to UI polish rather than deep UX engineering like undo, progressive loading metrics or perceptual performance work.

Evidence

Portfolio/src/components/resume/Skills.js - animated progress bars (framer-motion)

Portfolio/src/components/contact/Contact.js - success/error message flows

Portfolio/src/components/features/CardData.js - hover/transition UI patterns

Recommendations

Lead development of fullstack features that integrate AI generation with user billing and deployment pipelines (implement and harden the website generation, crediting and Stripe flows).
Build and harden production API endpoints and webhooks (security, signatures, retries, idempotency) for payment and AI tasks.
Implement end-to-end tests and CI checks, and add a11y and performance audits (Lighthouse, bundle analysis) to raise production readiness.
Improve client-side server-state handling (cache invalidation, optimistic updates and request cancellation) for the AI-driven editing flows.
