Top Rated Plus | 100% Job Success | Co-Founder & CTO of PropertyTools .ai, a live AI SaaS platform. I don't just write code - I build and run production systems that real businesses depend on daily.
Two things I do exceptionally well:
1. Full stack web apps & SaaS platforms (Next.js, React, Python, Django, FastAPI, Node.js)
2. AI agents, chatbots & automation systems (OpenAI, Claude API, LangChain, RAG, n8n)
🏆 PROOF, NOT PROMISES — live products I built:
- PropertyTools .ai — AI real estate SaaS I co-founded: Claude AI document analysis, Plaid bank integration, Stripe subscriptions, multi-tenant architecture
- BlueGrassHopper .com — multi-tenant fintech marketplace: Django, React, Stripe Connect payouts, 4 role-based dashboards
- BNTR.ai — AI chatbot builder that trains on your own data (React, Django, custom ML)
- GetOdin.ai — led a full Next.js → React migration that fixed a slow production app
- Recent client win: brought an unstable production app to life — "running in prod error free" (see reviews)
🔧 TECH I SHIP WITH DAILY:
Backend & APIs: Python (Django, FastAPI), Node.js (NestJS, Express), REST, GraphQL, WebSockets
AI & Automation: AI agents (LangChain, LangGraph, CrewAI), RAG pipelines, OpenAI GPT-4o, Claude API, chatbots, voice AI, n8n / Make / Zapier workflows
Frontend: React, Next.js, TypeScript, Tailwind CSS
Data & Infra: PostgreSQL, MongoDB, Redis, Supabase, AWS, Docker, CI/CD
Payments & Fintech: Stripe, Stripe Connect, Plaid, PayPal
🚀 VIBE CODED YOUR APP? I'LL MAKE IT PRODUCTION-READY.
Built something with Lovable, Bolt, v0, Replit, or Cursor and now it's breaking, insecure, or impossible to extend? This is one of my specialties — I take AI-generated codebases and turn them into stable, scalable products. Auth done right, database restructured, security holes closed, deployed properly. A recent client's unstable app has been "running in prod error free" for months (see reviews).
💡 WHY CLIENTS PICK ME:
- I run my own live SaaS — I think about your product like a founder, not a task-taker
- AI-native development: I use Claude Code and Cursor daily, so you get senior-level quality at 2-3x normal speed — you pay for outcomes, not hours of typing
- Working demos, not slide decks — I'll screen share real production systems on our first call
- 0–4 hour response time, clear communication, realistic timelines
✅ GREAT FIT: SaaS MVPs, AI agents & chatbots, vibe code cleanup & rescue, scalable APIs, fintech integrations, rescuing unstable production apps
❌ NOT A FIT: cheapest-bid shopping, gambling/adult content
🎯 GUARANTEE: Clear expectations set upfront. If I don't deliver against them, full refund.
Message me — I'm usually online and can jump on a call the same day.

I help organizations design, audit, and remediate digital platforms to meet WCAG accessibility standards and align with ADA, Section 508, and international accessibility requirements. My focus is on building systems that are accessible, scalable, and audit-ready without requiring a full internal accessibility team.
With 13+ years of experience across full-stack engineering and accessibility-focused development, I work at the intersection of compliance, usability, and system architecture. My background includes WCAG 2.0 / 2.1 / 2.2 Level AA implementation, accessibility remediation, and compliance engineering for regulated environments.

• WordPress/Wix/Squarespace accessibility remediation (themes, plugins, builders)
Technical Background:
Frontend:
React, Vue.js, TypeScript, modern JavaScript, performance-optimized UI development with accessibility-first component design
Backend:
PHP, Node.js, Python, REST/GraphQL APIs, MySQL/PostgreSQL, system architecture
Cloud & DevOps:
AWS, Azure, GCP, Docker, CI/CD pipelines, monitoring and reliability engineering
Integration & Systems:
Payment systems (Stripe, PayPal, Braintree, CyberSource), third-party APIs, secure application design
Practices:
Clean architecture, secure coding, accessibility testing workflows, code reviews, documentation, long-term maintainability
Working Approach:
I work hands-on across architecture, development, and accessibility remediation. For larger engagements, I collaborate with a small, consistent team under my direction to ensure quality, compliance continuity, and delivery reliability.
Closing:
I focus on building accessible systems that are not just compliant on paper, but functional, scalable, and usable in real-world environments. If you need accessibility expertise for a platform that must meet regulatory or enterprise standards, I can help you plan, audit, and implement it effectively.

Sara here! Are you truggling with a website that doesn’t convert, loads slowly, or just feels complicated to manage? I solve those problems. I’m a web developer, Shopify expert, and SEO & CRO specialist, building custom websites and online stores that not only look great but drive results.
I work with Shopify (including Shopify Plus), WordPress, WooCommerce, Wix, and Squarespace, helping businesses:
Launch high-converting Shopify stores with themes, dropshipping setups, and app integrations
Redesign or set up e-commerce sites that boost sales and engagement
Optimize websites to rank on Google and attract more customers
Make sites fast, secure, and easy to manage, so you can focus on running your business
I take care of the technical headaches from Shopify Liquid coding, HTML5, CSS3, JavaScript, to CMS product uploads, while ensuring your site is user-friendly and responsive on every device.
With a Master’s in Computer Science and years of experience as a Senior Web Developer at Digital Versa, I’ve built profitable sites for multiple clients. Now, as a freelancer, I focus on solving your specific online challenges, turning your website into a powerful tool that grows your business.
Also, If your traffic is steady but sales are down, something is broken… it’s just not obvious yet.
That’s where I come in.
I don’t just “work on websites.” I diagnose why they’re underperforming and fix the exact issues that are costing you conversions, whether that’s poor structure, slow load speed, weak UX, or backend inefficiencies.
Recently, I’ve helped stores:
• Recover dropped conversions without increasing traffic
• Speed up load times significantly (which directly improved sales)
• Simplify complex setups so owners could actually manage their store
Before jumping in, I’d want to quickly look at:
Where users are dropping off
What your add-to-cart vs checkout behavior looks like
Any recent changes that might have impacted conversions
If you’re open to it, send me your store link. I’ll point out exactly what’s going wrong and how I’d fix it.

22+ years designing enterprise systems built for reliability, performance, and long-term maintainability.
I currently serve as Head of Technology for OursTube, a video streaming platform, alongside consulting engagements for startups and growing businesses.
I've shipped 50+ platforms — a government compliance system
for 5,000+ Pakistan Railways employees (World Bank-audited),
an AI module that cut manual data entry by 85%, FinTech
backends handling payments across UK, UAE and Europe, and
a YouTube-style video platform with WebRTC real-time chat
serving thousands of concurrent users.
If you need someone to write a feature and disappear, I'm
not the right fit. If you need someone who thinks about
schema design, security, query performance, and what happens
at 3x your current load — that's exactly what I do.
━━ WHAT I BUILD WELL ━━
► FinTech & Payment Systems
Built complete payment ecosystems including Stripe Connect onboarding, subscriptions, creator payouts, webhook orchestration, payment abstraction layers, and multi-provider payment integrations (Stripe, Wise, Payoneer, JazzCash, EasyPaisa).
► Backend Architecture (Node.js / Laravel / NestJS)
Designed scalable RESTful and GraphQL APIs with optimized PostgreSQL queries, Redis caching, and clean service boundaries for high-performance enterprise applications
► PostgreSQL at Scale
Schema design, migration strategies, index optimisation.
I reduced a government system's query time from 15 seconds
to 200ms. Connection pooling, partitioning, full audit
logging for compliance.
► AI / OpenAI API Integration
Production AI systems using OpenAI GPT-4/4o with OCR, intelligent document processing, provider-agnostic architecture, prompt versioning, structured outputs, and enterprise workflow automation.
► Security & Compliance
JWT with refresh rotation, RBAC, OAuth 2.0, audit trails.
Passed World Bank security audit for a public-sector system.
I treat security as architecture, not a checkbox.
► Amazon SP-API / Shopify / E-commerce
Japanese marketplace integration, multi-vendor fulfilment
platforms, rate limit management, exponential backoff.
Real resilience patterns, not optimistic code.
► WordPress & WooCommerce (Custom & Complex)
Multi-vendor WooCommerce platforms with custom commission
logic, AJAX cart systems, ACF Pro integrations, and vendor
dashboards. WP Rocket + Cloudflare configuration. Custom
PHP plugins, payment gateway integration (Stripe, PayPal,
JazzCash), and performance optimization for high-traffic
stores. I debug codebases I didn't write — fast.
━━ PAST ENGAGEMENTS ━━
• Pakistan Railways (2021–2023) — Audit & Fuel Management
systems for 5,000+ staff. World Bank compliance. Query
optimisation: 15s → 200ms.
• YetiScanner AI (2024) — OpenAI GPT-4 document processing
for YetiForce CRM (Netherlands). 85% reduction in manual
invoice entry.
• Global Connect ERP (Bahrain, 2024–2025) — Oracle monolith
→ PostgreSQL microservices. 3× performance improvement.
• Ourstube Media (2025–Present, Current) — Head of Technology for a YouTube-style platform: Node.js microservices, WebRTC, custom AdTech, 4-provider payment abstraction. 60% faster video processing via CDN.
• Thread Production ERP (2024) — Multi-tenant Laravel 11
system for textile manufacturing. Complex RBAC across
multiple facilities.

━━ HOW I WORK ━━
I take a small number of engagements at a time so I can
give each one proper attention. I communicate daily, push
working code early, and flag risks before they become
problems. Timezone: PKT (UTC+5) — available for UK, UAE
and European business hours with overlap.
Whether you need it built, or need an architect to validate the plan and pressure-test the decisions before you build — that's work I do. If your project involves backend architecture, payment systems, AI integration, database performance, ERP/systems integration, or taking a messy codebase and making it production-ready, send me a message with what you're building. I'll tell you honestly if I'm the right person for it.
