I write AL and C# for a living. Mostly that means extending Microsoft Dynamics 365 Business Central, moving old Dynamics NAV databases onto it, and building the .NET services that let a POS, a web shop or a warehouse app talk to the ERP without anyone re-typing invoices.
I got into software around 2020 and ended up in the ERP world soon after. Since then most of my working hours have gone into Dynamics NAV and Business Central: reading C/AL that someone wrote in 2009, rebuilding it as AL extensions, and checking that the numbers still add up after go-live.
The part I like most is the edge of the ERP. Business Central is a very good ledger. It's less good at talking to a POS terminal in an airport, or to a .NET service that wants new orders every five minutes. That's where C# and ASP.NET Core come in, and where I spend a lot of my time.
Most of my clients are retail and duty-free businesses in the Gulf and the Maldives. I work remotely from Kathmandu, which is a couple of hours ahead of the Gulf, so I'm usually well into my day by the time they log in.
Six things I'm regularly hired for. Line numbers go up in tens of thousands, like they do in Business Central.
| Line No. | Description | Details | Unit |
|---|---|---|---|
| 10000 | Business Central development | AL extensions: table and page extensions, event subscribers, posting logic, API pages. Written so the next Microsoft update doesn't break them. | per app |
| 20000 | NAV to Business Central upgrades | From NAV 2009 R2 onwards. C/AL to AL, data upgrade codeunits, report migration and a cut-over plan that doesn't eat your whole weekend. | per database |
| 30000 | .NET development | ASP.NET Core Web APIs, background workers, Entity Framework Core and SQL Server. Boring, well-tested back-end code. | per service |
| 40000 | Integrations | POS, web shops, banks, anything with an API. OAuth 2.0, OData, custom API pages, Azure Functions. | per integration |
| 50000 | Reports | RDLC and Word layouts. I've migrated enough old NAV reports that I quite enjoy it now. | per layout |
| 60000 | Support | Performance problems, odd posting errors and "it worked yesterday" calls on live systems. | per month |
| Total Amount Excl. VAT | depends on scope | ||
A few projects I can talk about. Click a line to open it.
A customised NAV 2015 database moved onto Business Central 22. The C/AL modifications were rewritten as AL extensions, the business data went through upgrade codeunits, and the reports were rebuilt for the new platform.
Point-of-sale for airport duty-free retail, with store transactions flowing into Business Central for inventory, sales and financial posting. Airports don't close, so the integration has to keep up.
Ongoing enhancements to an existing Business Central environment: new fields, pages, processes and business logic, worked out with the client and shipped as AL extensions they can keep upgrading.
Classic NAV 2009 R2 reports don't carry over to Business Central, so they were rebuilt on BC 20: new datasets, new layouts, and the same documents finance and operations were used to.

Anish Poudel, Business Central Technical Consultant
Rajat Shah, Business Central Technical Consultant
Sanjay Shrestha, Business Central Technical ConsultantNotes from real projects, so I don't have to explain the same thing twice.
The technical half of a Business Central project: AL extensions, integrations, data migration, reports, upgrades from Dynamics NAV and performance fixes. The functional consultant works out what the business needs, and I make the system do it without breaking the next update.
Yes. I've worked on upgrades from NAV 2009 R2 and NAV 2015 to modern Business Central, including turning C/AL modifications into AL extensions, upgrading data and migrating reports. My upgrade guide covers how I approach it.
Yes. I build ASP.NET Core APIs, background workers and Azure Functions that use Business Central's standard and custom APIs with OAuth 2.0 service-to-service authentication.
Most of my clients are outside Nepal. I've delivered Business Central work for retail and duty-free businesses in Bahrain, the Maldives and the wider Gulf, all remotely from Kathmandu.
Business Central online and on-premises, plus Dynamics NAV from 2009 R2 onwards when there's an upgrade or an old system to keep alive.
