Project details

I build custom CRM and ERP web apps that fit how your business actually works - customers, invoices, bookings, inventory, roles, dashboards, and reports - on a modern, maintainable stack (React/Next.js + Node/NestJS + PostgreSQL).

The video shows ArkWave, a live multi-tenant travel CRM/ERP I built end-to-end: GST invoicing, bookings across flights/hotels/visa, a CRM with GSTIN, and real-time dashboards. I will build the same quality for your domain.

What you can expect:
 • A clean data model and the modules your business needs
 • A responsive UI with secure auth and role-based access
 • Dashboards, reports, and exports
 • Deployment and a handover walkthrough

I own delivery from architecture to production. Tell me about your business and I will propose the right scope.

About Alok

Alok R.Status: Offline
AI & Full-Stack Engineer | LLM/RAG, React/Node, Oracle Flexcube
Pune, India - 7:30 am local time
I'm a senior technical lead with 17+ years building production software, now focused on AI engineering and full-stack product development. I design and ship RAG systems and LLM agents (LangChain, LangGraph, FastAPI, pgvector) and full-stack apps (React/Next.js, Node/NestJS, PostgreSQL), and I've independently built and operate a portfolio of self-hosted products end-to-end.

How I can help:
• AI/LLM — Retrieval-Augmented Generation (hybrid search + reranking), LLM agents & tools, chatbots grounded on your data, FastAPI backends.
• Full-stack — React/Next.js + Node/NestJS apps, REST APIs, PostgreSQL/Redis, Docker.
• Enterprise & data — Oracle PL/SQL, Oracle Flexcube IS banking implementations & migrations, system integration, performance tuning.

Recent self-built products: an enterprise RAG document-Q&A platform, a LangGraph agent platform, a multi-tenant CRM/ERP and an e-commerce admin (NestJS/Next.js), an automated trading-analytics system, and an embedded AI voice assistant.

Background: 17 years across Oracle Financial Services, Netcracker, and IBM — leading onsite/offshore teams (8+ devs) for banking and telecom clients in South Africa, the Americas, and India. I own delivery from architecture through production. Let's talk about what you're building.

Revisions may occur after the delivery date.

Build & deliver

I set up the data model and modules, build the UI and APIs, load your data, then deliver with roles, deployment, and a short walkthrough.

Review the work, release payment, and leave feedback to Alok.
