Database for Fishing Company to be used for Invoicing and Reporting - Update
He did an excellent job updating and enhancing our sales and inventory database. He was very responsive, implemented new features quickly, and consistently delivered solutions in a timely manner. What stood out most was his strong troubleshooting ability—whenever issues arose, he identified the root cause efficiently and resolved them with minimal delay.
He communicated well throughout the project, was easy to work with, and adapted to our evolving requirements without any problems. I would definitely recommend him to anyone looking for a reliable developer for database updates, custom functionality, and ongoing system improvements. I would be happy to work with him again in the future.

Job Success
Karachi, Pakistan - 11:13 am local time
I am a full stack developer, database architect, and SaaS developer. I design scalable database systems, build production-ready web applications, and integrate AI into products that work for real users.
Full stack developer. Next.js. TypeScript. End to end.
As a full stack developer I own the entire stack PostgreSQL schema design, Node.js backend, Next.js and React frontend, REST API integrations, Stripe payments, and Vercel deployment. Need a full stack developer who takes ownership from database to deployment without hand-holding? Let's talk.
Recent full stack work includes a multi-tenant property management SaaS on Next.js and Supabase with role-based access, admin dashboards, and OpenAI integrations and a freelance marketplace with a GraphQL API layer, BullMQ background job queues, and row-level security enforcing per-user data isolation across clients and freelancers.
Database architect. PostgreSQL. Supabase. SQL. Production-grade.
As a database architect I design schemas from scratch normalization, ERD modelling, indexing strategies, query optimization, and Row Level Security policies. I migrate businesses from messy Excel and Google Sheets into clean, scalable PostgreSQL and Supabase systems with zero data loss and full audit trails.
Recent database work includes a fuel business management platform with complex relational schema covering customers, orders, deliveries, invoicing, and payment cycles and a POS system with real-time inventory tracking, sales reporting, and automated invoice generation, all built on Supabase and PostgreSQL.
Backend developer. Node.js. NestJS. REST APIs.
As a backend developer I build structured, scalable Node.js and NestJS APIs with TypeScript end to end modular architecture, dependency injection, guard-based authentication, and clean REST API layers. I design and implement authentication flows, role-based access control, webhook handling, and background job processing for production applications that need to scale reliably.
SaaS developer. Multi-tenant. Stripe. Production-ready.
As a SaaS developer I build complete products end to end authentication, database, Stripe subscriptions and webhooks, dashboards, role-based access, and deployment. I have delivered a business management platform with automated PDF invoicing, cron-based billing cycles, and email dispatch via Resend; a wedding management system with client records, fare packages, and booking history; and a lead management dashboard with WhatsApp automation via ManyChat and automated drip campaigns.
AI developer. OpenAI. Claude API. LLM integrations.
As an AI developer I integrate LLM APIs into production applications document processing pipelines, AI-powered workflow automation, structured prompt engineering, and AI-assisted data extraction. All API keys handled server-side, never exposed to the browser. I have built OpenAI and Claude integrations into SaaS platforms delivering real features, not demos.
Security. Supabase RLS. Multi-tenant isolation.
I implement Row Level Security on every Supabase project enforcing per-user and per-tenant data isolation at the database level, not just the application layer. RLS policies, protected API routes, secure file access via signed URLs, and environment variable hygiene are standard practice on every project I deliver.
Integrations. Automation. Third-party APIs.
QuickBooks API integration for financial data sync into web dashboards. Airtable integrations. ManyChat and WhatsApp API automation. Resend for transactional email. Stripe checkout, subscriptions, webhooks, and billing portals. REST API development and third-party service connections across every project.
How I work:
Daily updates, no ghosting. Honest timelines. 30+ hours per week. 0–4 hour response time. I use Cursor and Claude Code daily to move fast without cutting quality. Full code ownership transferred on every handover.
