Sonar — Accessibility-first React dashboard kit

An open-source React dashboard-kit library: zero-dependency SVG charts (area, bar, donut, sparkline) where every chart ships an aria-label summary and a visually-hidden data table, so screen-reader users get the same numbers as sighted ones — enforced with jest-axe in CI. Plus KPI tiles, a responsive stat grid, and filter primitives. Themeable through CSS variables that pair with my Fathom UI design system, and shipped as tree-shakeable ESM + CJS with types (tsup) and Storybook. It's the kit that powers my Pulse dashboard.

Pulse — Real-time transport & payments analytics dashboard

A data-dense analytics dashboard for an intercity transport operator: gross revenue, bookings, refund rate, seat-fill and payment-provider mix (Paystack/Monnify/Nomba), updating live. The charts are hand-built from SVG over a unit-tested scale/geometry layer — no charting library — and every one is fully accessible (aria-label summaries plus a visually-hidden data table, enforced with jest-axe). Client-side aggregation over ~10k transactions powers instant, URL-synced cross-filtering, and it's built on my own design system, Fathom UI. Tested with Vitest + Playwright.

Fathom UI — Accessible, published React component library

An open-source React component library published to npm (@engraya/fathom-ui). Headless behavior from Radix, themeable through CSS-variable design tokens (light/dark), shipped as tree-shakeable ESM + CJS with type definitions. Every component is unit- and accessibility-tested (Vitest + jest-axe), documented in Storybook, and released through a tsup build with CI.

Codraft — Real-time collaboration and document editing

Collaborative editor with live presence and secure sharing (Liveblocks + Clerk). Shipped end-to-end UI, auth, and persistence—focused on low-latency typing and clear UX under concurrent edits.

Delectable AI — Global recipes, smart search & recipe copilot 🌍🍽️

Discover dishes from a large recipe catalog with trending picks and cuisine-style browsing.

On every recipe, Recipe Copilot is page-aware—ask about substitutions, scaling, simpler steps, or allergy-minded swaps—with requests handled on a backend so API keys stay off the client.

Core Post Backend — blog & engagement API

Versioned Express REST API (`/api/v1`) for posts, nested comments, likes, and bookmarks on MongoDB. Users register and verify email via OTP email (Nodemailer); JWT protects mutations, with an extra database-backed verified-email check for write operations. List endpoints support query pagination (`page`), and auth-sensitive routes use express-rate-limit. Vitest and Supertest cover HTTP behavior against MongoDB when available.

Jobnest API — job board backend

REST API for job postings and applications built with Express and TypeScript. Mongoose models link users to jobs they create and jobs they apply to, with JWT-based sessions and role checks for admin-only user deletion. Request bodies for registration and login are validated with Joi; passwords are hashed with bcrypt. Routes are grouped under /api and /api/auth. No OpenAPI spec or health-check route is present in the repository.

SlideForge API

SlideForge is a production-grade RESTful API built with FastAPI and Python 3.12 that automates AI-powered PowerPoint generation. It exposes an async job-queue pattern — clients POST a topic and receive a job ID immediately (202 Accepted), then poll for completion before downloading the generated .pptx file. Slide content is synthesized by the Google Gemini API (JSON-mode, gemini-2.0-flash-preview) with configurable language, theme, and slide count. The generated files are assembled using python-pptx with three built-in themes (Professional, Minimal, Vibrant) and served as binary file responses with server-side path-traversal protection. The service layer follows dependency injection via LRU-cached FastAPI dependencies, structured JSON logging, custom exception hierarchy with typed error codes, per-IP rate limiting via slowapi, and a multi-stage Docker build running as a non-root user. No OpenAPI/Swagger UI is exposed in production (docs are disabled). A GitHub Actions CI/CD pipeline covers linting (ruff), static type checking (mypy), test coverage (pytest + httpx), and Docker image build.
