System analysis
I help clarify the goal, constraints, requirements, and expected result so the team solves a clear problem instead of working through assumptions.
Nicholas Volkhin
Systems architect
I analyze, design, and help implement websites, software, information systems, integrations, and data models for real business tasks.
I actively use AI tools in my work, so I choose the stack that best fits the task instead of sticking to familiar tools. My strongest practical background is in PHP, C#, PostgreSQL, and MySQL; I have also worked with JS, Python, Delphi, Go, PL/SQL, and T-SQL.
About
I usually join tasks where writing code alone is not enough: first the real requirement has to be understood, the solution has to make sense in practice, and the line between useful architecture and unnecessary complexity has to be defined.
That may mean a new project, redesigning an existing solution, integration between systems, data model design, bottleneck analysis, or preparing a clear technical specification for a team.
My preferred approach is engineering-first: understand the task, choose a sensible architecture, respect the constraints, and bring the solution to a working state.
What I can help with
System architecture
I design the system composition, module boundaries, interaction between parts, integrations, and rules for data processing.
Data models
I choose storage structures, relationships, indexes, constraints, and a data approach that fit real usage scenarios.
Integrations
API, XML, SOAP, import, export, exchange between systems, loading large volumes of data, and converting them into a usable format.
Improvement and refactoring
I analyze the current solution, identify weak points, propose a simpler structure, and help implement changes without unnecessary noise.
Implementation
I can not only design a solution but also participate in implementation: on my own or together with your team.
How I work
1
I understand the task
I clarify the goal, constraints, risks, current situation, and the signs that will show the task has been solved well.
2
I propose the structure of the solution
I show how to break the system into parts, how data and integrations should work, and what the stages and priorities should be.
3
I help bring it to a result
I help turn the scheme into a working solution without losing the meaning of the task on the way: no needless architectural cosmetics and no technology for technology’s sake.
Articles and materials
A few materials that make it easy to understand how I approach data, XML, SQL, libraries, and practical software development.
Working with XML as if it were an array, version 2
An article about streaming large XML files with XMLReader and yield. Useful when you need to process large exports without putting extra pressure on memory.
Importing the full FIAS database in 9 hours, How To
A practical article about processing a large FIAS XML dataset, parallelizing the workflow, and loading the data into PostgreSQL.
The ideal catalog, a base library
An article about a library for working with EAV and how to manage flexible data structures without turning the system into chaos.
xml-navigator / XmlExtractKit
A public library for typical XML tasks: selecting the required nodes, streaming processing, and converting XML into plain PHP arrays.
storage-for-all-things / EAV Manager
A repository and library focused on EAV, data structures, and practical work with catalogs and flexible entities.
Reviews
There are reviews of my work on Profi.ru. Below are a few short quotes, and the full review page is available by link.
“Quick to respond and helped me understand the task.”
“Everything was competent and to the point.”
“He explained how the algorithm works in detail.”
Contact
If you have a task that needs to be clarified, designed, or brought to a working result, write to me in any convenient way.
If it is more convenient, you can save my contact card and come back to the conversation later.
