software for individuals and businesses

backend development.

i develop application backends with c# and asp.net core. i design business rules, data models and access permissions around your project, supporting new apis and existing backend features with tests and documentation.

let’s discuss your project

when this service fits

we can work together when you need an api for a web or mobile product, a new module in an existing .net system or changes to business rules. scope covers user roles, data consistency and failure cases as well as endpoints.

we start with acceptance criteria and example requests and responses. i collect feedback through a working api during development. handover includes source code, openapi documentation, setup instructions and the agreed tests. architecture follows team size and business needs; microservices are not necessary for every project.

project deliverables

  • rest api and openapi documentation
  • business rules, validation and authorization
  • database model and automated tests

c# · asp.net core · entity framework core · postgresql / sql server

example scopes of work

an api for a new product

we define the data model, access rules and service contract for workflows such as users, orders or stock. the first release follows one working flow, with further features added around actual needs.

features in an existing application

i review the code and database to identify how a change affects other modules. regression checks help verify existing behavior when introducing new business rules.

data correctness and authorization

we identify scenarios such as invalid requests, unauthorized access and repeated operations. validation, transactions and error responses are designed around the requirements.

what we need to start

share the application goal, user roles, a core workflow and any existing api documentation. where code access is needed, we agree separately on its scope and permissions.

experience and work samples

my experience at turkmen holding covers c#/.net backend development in existing monolithic textile erp modules. you can also inspect my personal project source and technical articles.

relevant technical example

learn input validation, business rules and problem details in asp.net core through a small price calculation example.

what does your .net api say when a request is wrong? ↗

before we start

can you work on my existing .net project?
yes. after reviewing the .net version, dependencies, tests and development environment, we can define a feature or maintenance scope.
can i engage you for backend development only?
yes. i can work with your frontend or mobile team through an agreed api contract. interface development can be considered separately.
are the database and tests included?
the agreed scope includes a data model, necessary database changes and automated tests. production release, data migration and operational responsibilities are agreed separately at the start.

let’s take the first step on your project.

share your requirements, existing system and target date. we can assess the scope and working model that suit your project.
