Senior Dynamics 365 Business Central Technical Consultant \| AL Language & Extensions Expert \| Hybrid Full\-Stack Engineer \(Angular v12/v17 & Ionic\) \| Enterprise ERP Integrations & Custom Web APIs

## About

I'm a Dynamics 365 Business Central Technical Consultant and Full\-Stack Engineer with 5 years of enterprise software experience — 3 spent exclusively architecting AL Extensions, custom APIs, and ERP automation for international clients across banking, renewable energy, and manufacturing\. My defining edge is hybrid: I operate across the full technology stack — from deep BC extension development in AL and C/AL, all the way to building Angular v17 and Ionic frontends that consume live Business Central data through custom OData and REST APIs\. Most consultants stop at the ERP boundary\. I own everything on both sides of it\. That dual capability has driven measurable outcomes at scale\. At Hong Leong Bank, I engineered a 3\-stage Employee Claim Approval engine using AL EventSubscribers with zero disruption to standard ledger postings\. At Cenergi, I architected an end\-to\-end automated procurement matrix — from Purchase Requisitions through Bid Collection to PO conversion — eliminating manual handoffs entirely\. Across all engagements, my workflow automation extensions have consistently reduced operational processing times by 70%\. I also built and scaled a Government Grievance mobile application on Angular \+ Ionic \+ Firebase that now serves 10,000\+ active users in production\. Core Technical Stack: D365 Business Central: AL Language · C/AL · Tables · Pages · PageExtensions · TableExtensions · Codeunits · EventSubscribers · Report Layouts \(RDLC/Word\) · Data Migration · Version Upgrades APIs & Integration: Custom OData APIs · REST Web Services · SOAP · Table APIs · Postman · Real\-time ERP\-to\-Web Sync Frontend & Mobile: Angular v12/v17 · Ionic v3/v5 · TypeScript · JavaScript · HTML5 · SCSS · Bootstrap 4/5 Cloud & DevOps: Firebase Auth · Firebase Cloud Messaging \(FCM\) · Git · GitHub · VS Code I'm actively targeting Senior BC Consultant, Solution Architect, or Technical Lead roles with Big 4 consultancies, Microsoft Gold Partners, or enterprise IT firms in Kolkata — Salt Lake Sector V / New Town preferred\. If you're scaling a Dynamics practice and need someone who can architect the ERP core and own the integration layer simultaneously, let's talk\.
