Most MVPs fail not because of a bad idea-but because they are not built to last.
I am a Senior AI SaaS Software Application Developer specializing in Lovable, Claude Code, Supabase, and Replit, helping founders, startups, and businesses go from idea to production-ready product in weeks, not months. Whether you need a full-stack MVP, an AI-powered SaaS platform, or automation workflows that eliminate manual work, I deliver systems built to scale from day one.
🚀 What I Build
Full-Stack MVP & SaaS Development
From schema design and architecture to live deployment. I build SaaS platforms, client portals, internal tools, CRMs, and enterprise dashboards using Lovable + Supabase with real auth, real data models, and security baked in from the start, not bolted on later.
Predictive Healthcare Intelligence Platform
Built a secure multi-tenant healthcare intelligence platform that unified clinical and operational data into a centralized system for real-time decision-making and early risk detection. Developed attendance intelli
Automation & Workflow Engineering
I connect your tools using Make . com and n8n, ensuring your CRM communicates with your billing, your AI model interacts with your database, and humans only engage with what truly requires human judgment. No more manual copy-paste between systems.
Broken MVP Rescue
Already built something, but it's fragile, slow, or disconnected? I audit, refactor, and stabilize it so it can handle real users and real growth.
🏆 Notable Projects
🤖 AI Mental Wellness Assistant: Built and deployed an AI-driven mental wellness app with personalized chat, emotion tracking, voice input, and intelligent automation using GPT, React Native, and Firebase.
📊 Uncharted: An AI-powered data visualization tool that transforms CSV/Excel files into smart, interactive charts instantly. Built with GPT integrations and seamless UX for rapid decision-making; zero manual setup required.

🤝 Why Clients Work With Me
End-to-end ownership: I manage scope, architecture, build, and launch. No agency overhead, no middlemen.
AI-native development: I don't just use AI tools; I build AI into your product as a core feature.
Production-first mindset, as every project ships with real security, real scalability, and real maintainability.
Transparent communication: Clear milestones, regular updates, and clean handovers every time.
I ask the right questions first; the fastest way to build the wrong thing is skipping the architecture conversation.
Ready to build something real? Send me a message and let's talk about your project. Tell me: what's the one process in your business that still lives in a spreadsheet or someone's inbox that shouldn't? I'll tell you exactly how we'd fix it.

40+ Years of Combined Pre-AI Engineering Experience
✅ Top Rated · 100% Job Success
✅ Shipping production software ~3x faster
✅ Senior Team, Not Solo Freelancers
I'm Waleed Iqbal, Co-Founder of Fivex Labs. I've done a lot of development before the AI era, and now use AI as leverage, not as a crutch. I don't "vibe code" — I architect with structural integrity, then move fast. You work with one accountable expert who owns your project end-to-end, not a rotating cast.
What I build:
◆ SaaS & MVP platforms — B2B/B2C products from spec to production in weeks, not months.
◆ Web apps — Next.js + React, headless CMS, edge-deployed. 90+ Lighthouse, SEO-first.
◆ Mobile apps — React Native, one codebase for iOS & Android.
◆ Cloud & infrastructure — AWS (ECS, Fargate, RDS), Terraform, CI/CD, built to scale.
How I work:
The philosophy I believe in, and honestly, has worked for me for so many years is to under-promise and over-deliver. I scope conservatively and aim to beat it. Clear communication, senior ownership, and maintainable code you won't have to rebuild in six months.
Stack:
Next.js · React · TypeScript · Node/NestJS · PostgreSQL · React Native · AWS · Stripe · Terraform · Headless CMS (Contentful, Payload)
If you want a partner who ships real, maintainable software fast — not a prototype that collapses under load — let's talk.

When a business operation runs on people instead of systems, or when an AI layer drifts because it's answering from generic knowledge instead of the company's own data, or when three platforms are supposed to sync and none of them do, that's the kind of system I built.
I build AI systems using Laravel and Python as the foundation. RAG pipelines, multi-agent workflows, LLM integrations, production backends with deep third-party integrations, compliance-grade where the domain demands it.
✦ Work that reflects this:
» Built Therapy adherence workflow engine for a home medical equipment provider, 40+ states, millions of patients. Medicare only reimburses CPAP if documented compliance is proven within a fixed window. Built a system that monitors 12 trigger types per patient, low usage, mask leak, high AHI, missed downloads surfaces them by proximity to their reimbursement deadline, not just trigger volume.
Every outreach outcome and compliance date writes back to the ERP in the same session. Integrated with device telemetry. Built each trigger type independently, a generic handler for all 12 would have made compliance auditing unmanageable at that scale.
» Designed Patient intake pipeline for the same company. Agents were triaging faxes manually, re-keying data into the ERP, entering insurance tiers separately. Replaced the whole thing, document triage, patient matching, primary/secondary/tertiary insurance write-back, sales order creation, document attachment, all through the ERP's services layer in one session. ~70% reduction in intake processing time.
» Shipped Virtual-first outpatient care platform for a NASDAQ-listed healthcare clinic. Two treatment journeys: overactive bladder and menopause. Symptom checking, daily tracking tools, behaviour recording, compliance reports auto-distributed to ordering physicians. Integrated Auth0, Redox, SurveyJS, Kommunicate, Convo, Twilio, Logrocket. Compliance surface: HIPAA, HITRUST, OWASP, SOC2, CURES.
» RAG-based AI operations assistant for a 30-year insurance consultancy. Hard requirement: cannot answer outside its approved document scope. Each agency gets its own assistant trained only on their SOPs, no generic drift. Survey engine auto-generates customised audit guidelines per agency from submitted responses, versioned, admin-approved, downloadable as compliance PDFs. Audit handling time down 45%, staff training ramp-up cut by ~50%.
» Loan origination flow for a non-bank lender, lead to settlement, with a live three-way sync between the custom platform, HubSpot, and the origination system. Any status change propagates to all three without manual reconciliation.
» AI email triage system on N8N, classifies support, sales, and job applications, generates branch-specific replies using separate prompt templates per category, logs to Airtable, posts Slack summaries. Architecture built for a multi-agent upgrade, classifier, responder, and auditor agents running independently with shared memory.
» E-commerce: AI fraud detection for bulk orders, automated product description and meta ad generation, AI image and media creation, OpenAI, Gemini, and Claude running in production on a high-volume DTC platform.
✦ Stack: Laravel · PHP · Python · React · Node.js · LangChain · OpenAI · Claude · Gemini · RAG · Pinecone · FAISS · Weaviate · Filament · Laravel Nova · PostgreSQL · MySQL · Redis · Docker · AWS · GCP · Brightree · Redox · HubSpot · Twilio · N8N · Auth0 · ElevenLabs
✦ Compliance: HIPAA · HITECH · HITRUST · GDPR · SOC2 · OWASP · PCI DSS · CURES
