The Story

Product-Minded Engineering

Over the past 3+ years, I've built Flutter apps for production workflows across service management, ticketing, inventory, and secure local storage. My focus is mobile architecture, reliable API integration, performance-minded UI, and product flows that stay understandable for real users. I also use MERN and AI integration skills to understand the backend and product context around the mobile experience.

Full-Stack Context

MERN skills help me debug integrations, understand APIs, and collaborate better with backend teams.

How I Build

Engineering Philosophy

I care about mobile apps that stay reliable after the demo: clear architecture, sensible fallbacks, secure handling of user data, and interfaces that help people finish work faster.

01

Design mobile flows around real usage, poor networks, and recoverable failure states.

02

Keep state predictable with Riverpod or Provider and separate UI from data logic.

03

Build security into the product: auth, local storage, permissions, and privacy-sensitive UX.

04

Use AI integrations as helpful product layers, with validation and fallback behavior.

Flutter-Led Project Work

Production mobile apps first, with MERN projects included as supporting full-stack proof.

Enterprise B2B Expense SaaS
Flutter Production + MERN
Zarf — Expense Suite

Problem: B2B expense tracking is slow and lacks GCC/UAE compliance (VAT, TRN). Solution: A three-tier ecosystem with a Flutter mobile client (receipt scanning), React dashboard (admin audit & analytics), and Express API (hardened, llama AI receipt OCR).

Impact: Instant AI receipt parsing under 2s, Stateful Shell tab caching (0ms lag), and regional TRN/VAT compliance checks.

MPD - CA Service App

Problem: client-CA requests were scattered. Solution: a Flutter service app with status tracking, Firebase sync, and structured information screens.

Impact: reduced manual coordination across daily CA service workflows and supported 3 production versions.

Implementation-First Project Walkthroughs

Three enterprise-grade projects that show architecture, security, and end-to-end feature ownership.

B2B Enterprise SaaS Flutter + React + MERN + AI

Zarf

Premium B2B SaaS corporate expense management suite custom-built for SMEs in the GCC/UAE. A complete ecosystem consisting of a Flutter mobile client (receipt scanning), a React web portal (admin auditing & dashboards), and a hardened RESTful Express backend API featuring instant AI OCR receipt parsing under 2 seconds.

Regional compliance Engineered to support the GCC tax landscape, integrating strict UAE Tax Registration Number (TRN) validation, standard UAE 5% VAT rate calculations, and dynamic currency conversions back to AED base currency.
Mobile Caching Implemented StatefulShellRoute.indexedStack inside Flutter's GoRouter architecture, caching tab sub-navigators to ensure instantaneous transitions (0ms lag) and eliminate duplicate network requests.
Adaptive Layouts Built a role-adaptive mobile scaffolding system that morphs the navigation (3-tab for employees, 4-tab for managers/admins) on the fly, loading live review counts and badge updates from the backend.
AI Cost-Sentry Mitigated LLM billing risks by mounting a strict, dedicated aiRateLimiter (10 requests per 15 minutes per IP) on AI routes, capping file uploads to 5MB, and sanitizing error stack traces.
DevOps & Hardening Programmed Express security middleware (HSTS, SAMEORIGIN, CSP) to prevent clickjacking/XSS, resolved static SPA routing 404s via Vercel regex rewrites, and designed a bash pipeline (build_apk.sh) to auto-compile and version APK releases.

Highlights

  • Complete three-tiered ecosystem: Flutter client, React dashboard, Node.js API.
  • Regional TRN & standard 5% VAT tax calculations built directly into the engine.
  • Zero lag (0ms) routing with Flutter's StatefulShellRoute.indexedStack.
  • Dynamic, role-adaptive scaffold presenting dynamic screens and live badges.
  • Groq SDK integration using llama vision model for structured JSON receipt scans in < 2s.
  • Production-hardened Express API with HSTS, CSP, and rate-limiting.
  • Automated Gradle versioned APK compiler bash pipeline.

MERN + AI Full-Stack MERN + AI

CivilEye

Full-stack MERN complaint management platform with role-based workflows for User, Investigator, Admin, and Super Admin. Added AI-assisted complaint triage with Groq to suggest complaint category, priority, and reasoning during intake while keeping the core case workflow secure and non-blocking.

Problem Manual complaint handling was slow, opaque, and difficult to audit. The AI enhancement improves intake by helping users pick better categories and giving admins/investigators an early priority signal.
System Design MERN architecture with separate frontend/backend apps, role-protected complaint flows, and a protected triage endpoint that calls Groq, validates JSON, and stores AI metadata on complaint records.
Security JWT auth, role-based protected routes, bcryptjs hashing, OTP verification, environment-based secrets, Multer upload handling, and a backend-only Groq API key that is never exposed to the frontend.
AI / Intelligence Groq API with llama-3.3-70b-versatile returns structured JSON for suggested category, priority, and reasoning; if the AI call fails, the complaint workflow continues normally.
Post-release Improved queue prioritization, investigation progress visibility, safer resolve confirmation, and AI metadata review so admins and investigators could act on live case feedback more effectively.

Highlights

  • Built a full-stack MERN crime reporting and case management system.
  • Implemented role-based workflows for users, admins, investigators, and super admin.
  • Added AI-assisted complaint triage with Groq for category and priority suggestions.
  • Improved case workflow with public investigation progress and internal notes/evidence separation.
  • Added secure authentication with JWT, OTP verification, protected routes, and environment-based secrets.

Side Project Mobile Security

IronVault

Offline-first Android secure vault for storing passwords, cards, bank details, secure notes, and documents with local encryption, private access, and no cloud dependency by default.

Problem Sensitive data is often scattered across insecure notes and chat apps.
Architecture Feature-first layered modules with separated core, data, domain, and feature responsibilities, Riverpod state management, local encrypted persistence via Drift + sqflite, and secure storage for auth-related secrets.
Security Encrypted vault, hashed PIN, biometric unlock, recovery-key workflow, persistent PIN cooldown, auto-lock, and Android screenshot protection.
CI/CD Two GitHub Actions workflows: flutter analyze runs on every push and pull request to main for continuous code quality checks; a tag-triggered release workflow restores Android signing from repository secrets, builds a signed APK, runs apksigner verification, and publishes to GitHub Releases with CHANGELOG-driven release notes.
Post-release Iterated on crash reporting, recovery-key handling, encrypted backup flows, and update checks to make the vault more stable, recoverable, and production-ready over time.

Highlights

  • Offline operation without cloud dependency.
  • Password analytics, category-based organization, and dynamic multi-item flows.
  • Encrypted backup/restore, CSV import/export, and a recovery-aware UX flow.
  • In-app update checks, privacy/support surfaces, and security-focused UX decisions.
  • Tag-triggered GitHub Actions pipeline — signed APK build, apksigner verification, and automated GitHub Release publish with CHANGELOG-driven notes.
