Project details
Most businesses outgrow spreadsheets fast, especially in construction and retail where you need inventory, projects, and financials all in one place.
I built a complete, production-grade ERP from scratch, now available as a custom service for your business.
No licensing fees. You own the code.
Built for your workflows, not a generic template you work around.
Already built and live in production:
• Double-entry accounting, GL, Trial Balance, P&L, Balance Sheet
• Inventory with real-time stock tracking
• Full purchasing cycle — PO → GRN → Invoice → Payment → Returns + Supplier Refunds
• Full sales cycle — SO → Delivery → Invoice → Receipt → Returns + Customer Refunds
• Asset management, assign to projects, track repairs and availability
• Project accounting with profitability reports
• Multi-company + role-based access control
• Executive CXO Dashboard
• IPC billing for construction clients
Stack: FastAPI · PostgreSQL · React · TypeScript · Docker
I use disciplined development, most modules ship in 1-2 weeks instead of months.
Need a module added, a full system built, or an existing ERP customized? Let's talk.

SELECTED RESULTS
✅ Private GPT assistant for enterprise data using LangChain, OpenAI, and Pinecone. Let non-technical teams query internal systems in plain English while meeting strict security and compliance requirements.
✅ Power BI analytics suite for GSK connecting SQL, Databricks, and Power Query across multiple regions. Cut manual reporting effort by 40%.
✅ Multi-tenant SaaS platform built with Django, React, and AWS, with billing, role-based access, and analytics dashboards. Scaled to hundreds of active users with a 50% efficiency gain.
✅ AI resume screening tool using spaCy and FastAPI. Reduced candidate screening time by 70%.
✅ AI-powered breast cancer diagnosis platform and Text-to-SQL systems using LLMs for clinical and enterprise environments.
I work with organizations that have real data, real workflows, and real stakes, including global enterprises and large government bodies.
WHAT I BUILD
AI and LLM Systems: RAG pipelines, private GPT-style agents, document intelligence, multi-agent workflows, MCP server integrations.
SaaS Platforms: Django, FastAPI, Flask, Laravel, React, Vue.js, AWS. Multi-tenancy, billing, and role-based access built in from day one.
Data and Analytics: SQL, Databricks, Python, Power BI. Operational dashboards to executive reporting.
Business Automation: CRM, ERP, and third-party API integrations across sales, finance, and operations.
I take full ownership of complex builds. Architecture decisions, implementation, deployment, and handoff. Clients return because they trust both my judgment and my execution.
If you have a system to build or a process to automate, message me. I will review your requirements, flag the risks upfront, and tell you exactly how I would approach it before we agree on anything.
