software for individuals and businesses

maintenance and performance.

i review code and databases to identify issues and prioritize them by their impact on business processes. i verify fixes and performance improvements with tests, and report changes and measurable results.

let’s discuss your project

when this service fits

i offer review and improvement support for slow screens, recurring errors or a .net application that has become difficult to maintain. code and database review, prioritized findings and agreed fixes can be planned as separate deliverables.

we first define the review question and access boundaries. performance work starts with a baseline and compares the result after changes under the same data and conditions. the report includes findings, changes and measurement limits; an improvement percentage is not promised before review.

project deliverables

  • issue analysis and prioritized work items
  • bug fixes, query or code improvements
  • regression tests and change notes

example scopes of work

ef core and sql query performance

i reproduce the affected screen or api request and inspect measurements such as query count and duration. unnecessary reads, tracking, pagination and index use are possible review areas.

code review and a maintenance plan

i review the areas requiring changes, error handling and test coverage. findings are ordered by business impact and implementation effort in a practical improvement list.

bug fixes and regression checks

i establish the conditions of the failure and expected behavior. a repeatable check verifies the fix, with related workflows reviewed for unintended effects.

what we need to start

share the affected operation, reproduction steps, .net and database versions and business impact. examples with personal data removed are enough to start. any required technical access is agreed after the scope is clear.

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

recognize n+1 queries, early materialization, unnecessary tracking, growing joins and deep pagination through an order list you can run locally.

silent ef core performance killers and how to fix them ↗

before we start

can i request a review report only?
yes. a code review, findings and prioritized recommendations can be a standalone consulting scope. your team can implement the fixes, or we can plan them together.
how do we verify a performance improvement?
we compare before and after using the same data, query and working conditions. relevant indicators such as response duration and query count are reported alongside environment differences and measurement limits.
can you provide ongoing maintenance?
yes. we can agree on a work queue, communication frequency and allocated time. response times and support hours are agreed separately.

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.
