Portfolio / Professional Profile

I am a backend / fullstack developer with a strong focus on applied automation, integrations, internal portals, CRM/ERP-like systems, and complex business logic design. My journey began with applied web tools for clients' real-world processes and has grown over time into architectural work on exchanges, performance, security, fault tolerance, and platform design.

Over my years of work, I have progressed:

from developing discrete modules, internal portals, and automations;
to building systems that link users, data, equipment, external services, and regulated processes;
to a level where I think not only in code but also in architecture, business scenarios, data integrity, SLA, security, and further product evolution.

What I have worked with

internal portals, CRM, ERP-like systems, and administrative panels;
integrations: 1C ↔ Web ↔ CRM ↔ API ↔ external services;
production systems, specifications, calculations, tasks, and technological scenarios;
medical systems with hardware circuits, logging, and processing stages;
educational systems, personal portals, electronic journals, dynamic forms, and dashboards;
corporate portals and CRM circuits on Bitrix24;
bots, chat management panels, content, and communication scenarios;
crypto-financial and real-time platforms with queues, WebSocket, trading circuits, and distributed integrations;
my own plugins and technical libraries for Yii2, which I used in real projects.

My Growth Phases

Innova Systems

During this phase, I worked deeply on applied automation, internal calculations, production modules, and R&D directions.

developed internal web tools and inventory modules;
designed systems for production data, specifications, and calculations;
built ERP cores with roles, permissions, materials, and cost analysis;
worked with Yii2, Laravel, Node.js, MySQL, Linux, Docker;
simultaneously moved into research areas: Web3, crypto-node staging infrastructure, concurrent transactions, latency, deadlocks, and transactional security.

It was here that I formed a strong foundation in applied logic, integrations, and non-standard business processes. I stopped viewing a project as a set of pages and began to see the system as a model of a company's real operations.

Prime Systems Group

In this phase, I moved into a more complex engineering and leadership role.

entered the project as an external developer to stabilize a troubled module;
restored the working state of a critical circuit;
later became the lead developer and then Technical Lead;
designed backend modules and real-time Web ↔ C++ agents exchanges;
led interactions between backend, C++, QA, security, and sysadmin teams;
was responsible for release quality, SLA, and system stability.

Here, I grew toward architecture and technical leadership. The primary focus shifted from writing individual functions to managing complexity, module consistency, integration stability, and responsibility for a critical production circuit.

DataSoft

This phase strengthened me as an architect of integrations, performance, and internal platforms.

simultaneously develop and maintain several corporate systems;
design exchanges between 1C, personal portals, CRM, and external systems;
stabilize APIs, cache layers, queues, transactional operations, and JSON-contract exchanges;
perform security audits of routes, ACL, OAuth, API exposure, and risk models;
eliminate race conditions, timeouts, freezes, and duplicates in distributed scenarios;
participate in the refactoring of critical modules and architectural control of complex systems.

At this level, I no longer work merely as a feature developer, but as an engineer who designs stable exchange circuits, anticipates system bottlenecks, and establishes the rules by which a project can evolve without chaos.

How My Level Has Changed

initially, I solved specific local business tasks through web tools;
then I began designing entire internal systems: roles, data, calculations, documents, integrations, logs, and interfaces;
after that, I grew to a level where I can take over a troubled project, stabilize it, redesign critical nodes, and bring it to a working state;
later, my focus shifted toward integration architecture, fault tolerance, security, exchanges, highload scenarios, and platform design;
now I increasingly think like a designer: I see not only the current task but also how the system should scale, where its points of failure will be, how to link it with external circuits, and how to lay the foundation for further product growth.

Key Project Directions

Production and ERP Logic

specification processing system for furniture production;
internal portal for consolidating preliminary estimates;
CRM/ERP platform for furniture production and inventory management;
early internal shop and salon CRM;
unified food service platform with site, mobile app, and internal panel.

In these projects, I formalized real business processes, translating production and operational rules into code, calculations, documents, processing routes, and domain models.

Education and Personal Portals

residency personal portal with dynamic forms and 1C integration;
refactoring and stabilization of an electronic journal on Next.js with 1C integration;
internal management analytics dashboard for university;
MAX-bot and the MAX-Control concept as a platform for chat and bot management.

Here, I grew toward integration architecture, JSON contracts, form design, managing large data circuits, and designing digital ecosystems around organizations.

Medicine and Hardware Integrations

medical instrument processing system with step-by-step tracking;
sensors and devices that sent events via API;
server portal on Yii2 with logging, processing stages, and a dashboard.

This area showed me how to connect web, hardware, events, statuses, and regulated processes in a single system.

Corporate Portals and CRM

work with Bitrix24 as a major CRM platform;
analysis and development of productivity modules, contract circuit, tasks, cron, and webhooks;
practical development of my own CRM-thinking based on an out-of-the-box corporate platform.

This experience gave me a more mature understanding of how corporate internal systems are built and developed in real companies.

Fintech, Real-time, and Complex Integrations

cryptocurrency trading platform;
backend, real-time, WebSocket, queues, wallets, orders, KYC, P2P, and administrative circuit;
integration of the web platform with a discrete trading circuit processing environment.

This experience strengthened me in highload scenarios, distributed systems, real-time processing, and complex product platform architecture.

What Especially Characterizes Me

I can enter complex subject areas, not just standard web tasks;
I work well where real-world business processes need to be translated into domain models, APIs, and interfaces;
I can perform expert analysis of systems, integration circuits, and business processes before active development begins;
as a systems engineer, I understand infrastructure, network security, and can perform audits of a business's entire IT structure;
I can stabilize and resuscitate troubled projects after other developers;
I can design exchanges between several systems and reduce chaos in integrations;
I think about performance, security, data consistency, and further scalability;
I can not only write code but also build the technical foundation on which a project can continue to live;
I am evolving toward system design and platform thinking rather than just task execution.

What I Already Have in My Portfolio

production and ERP projects;
personal portals and educational systems;
a medical case with hardware and API;
a large fintech/crypto project;
CRM focus and experience with Bitrix24;
my own Yii2 plugins and technical libraries;
next-level product ideas where I already think in platforms rather than separate pages.

Where I Have Grown and Where I Am Heading

Currently, my level is closer to a developer-designer and integration architect of application systems.

I already work confidently at the intersection of backend, integrations, domain logic, and architecture;
I can think about the system as a whole, not just my piece of code;
I can join at the analysis stage and deconstruct not only the code but the process logic, risks, points of failure, and architectural constraints;
I understand the relationship between applications, infrastructure, the network, and security across the entire IT environment;
I can see how a product should evolve in future versions;
I can link engineering implementation with real business goals;
I am moving toward an even stronger role: internal platform architecture, integration circuits, highload, security, and designing mature corporate products.
