.NET Development Company in
Pune
ASP.NET Core APIs, Windows-to-cloud moves, and C# domain logic for Pune companies that already bought Microsoft—SQL Server, Entra ID, and Excel-heavy finance teams.
Pune still runs a lot of the economy on Microsoft. We speak that stack fluently.
Banks’ vendors, auto OEMs’ suppliers, and older Pune IT departments standardised on C#, IIS, and SQL Server for a reason: hiring, tooling, and auditors understand it. Unitas’ .NET practice is for those environments—not a lecture on why you should rewrite in Node. We build ASP.NET Core APIs, hang them on Azure or your on-prem IIS, and keep domain rules in C# where your existing team can read them.
Hadapsar engineers pair with React on the front when needed. If your pain is a 12-year-old .NET Framework WinForms app, that work is scoped with the legacy modernization page; this page is the healthy .NET build and API standard.
Key Highlights
- ASP.NET Core minimal APIs or clean architecture when the domain is thick
- SQL Server done properly (indexes, TVPs, not N+1 from the SPA)
- Entra ID / Azure AD for GCC-style SSO
- Azure DevOps or GitHub Actions to IIS/App Service
.NET surfaces we deliver
Different from the React page: this is the server, data, and Microsoft identity story.
Line-of-business APIs
Order, inventory, and pricing rules in C#. Versioned endpoints so a Pune SPA and a mobile client can coexist.
Azure landing
App Service, Key Vault, private endpoints. We will not dump connection strings in appsettings on a VM named TEST2.
SQL Server engineering
Schemas, jobs, and reporting databases. Excel Power Query is a consumer, not the system of record.
Integration on the Microsoft side
Graph, SharePoint, Dynamics when you already pay for them—scoped, not “we integrate everything.”
Background workloads
Hangfire/Queues for e-invoice, email, and file generation so IIS request threads stay boring.
Hardening
OWASP basics, secret rotation, and audit logs your ISO questionnaire expects.
Microsoft-heavy Pune buyers
If you are a greenfield Node startup, the custom software page may fit better.
Auto suppliers (PCMC)
EDI-ish files, scheduled jobs, SQL. C# remains the least surprising choice for their IT head.
Financial services vendors
Need audit trails and on-prem options. We do not fake a bank-core replacement.
GCCs on Azure
Landing zones and identity. Code reviews that look like their global templates.
ISVs selling to SMEs
Licensing, multi-tenant SQL or catalog-per-tenant—decided explicitly.
C# / Azure decisions with consequences
Stopped using EF to ‘just include everything’
A Pune OEM portal timed out on order history. We introduced a read model and Dapper for that path; writes stayed in a transactional service.
Moved secrets out of web.config
An IIS farm still had production passwords in a share. Key Vault plus managed identity; rotate without a full redeploy theatre.
Idempotent e-invoice worker
IRN generation retried safely. Finance stopped creating duplicate invoices after timeout.
.NET delivery
Contracts and data first. Controllers are the last 20%.
Domain & threat sketch
Entities, invariants, and who can call what. Authn vs authz written down.
Solution template
One repo layout, one logging style, one exception policy. Pune juniors can join without archaeology.
Vertical API slices
Each slice has tests around the money rules, not just 200 OK.
Ops rehearsal
Backup, migrate, and rollback on a staging SQL that looks like production volume.
Runbook
Who gets paged in IST, how to replay a queue, where logs live.
Why Unitas for .NET in a city full of C# institutes
Training institutes produce syntax. Production .NET is transactions, identity, and boring operations. That is the gap we fill.
We will keep SQL Server
No drive-by Mongo rewrite because a blog said so. If you need Postgres, we will argue it on purpose.
React is optional, not mandatory
Blazor is available when your team is C#-only; we will not force it if you already have a React bench.
Azure without cargo cult
If on-prem IIS is a compliance requirement, we stay there and still add CI.
Legacy cousins
Framework 4.8 to Core is a modernization project with a cutover. We will not “just retarget” a 2 GB solution and call it done.
.NET snapshots
Server-side outcomes—distinct from React case studies on the frontend page.
Policy document generation queue
Moved PDF generation off IIS into workers. P99 of the user request path fell below 400 ms; PDFs still landed in blob storage with a status API.
Pricing rules API
Replaced a stored-procedure maze with C# policy objects and characterisation tests. Sales Excel still consumed it; rules became reviewable in PR.
.NET commercial shapes
APIs are cheaper than full ERP. Do not buy a platform if you need an endpoint.
API slice
One bounded context in production with auth, logs, and CI.
