Full-stack development • SaaS • Linux / DevOps • automation • hardware integration

I build complete systems from interface to server and device.

Web applications, SaaS platforms, APIs, dashboards, Linux infrastructure, automation and real-world device communication — designed, deployed and supported as one practical engineering workflow.

Full-stack engineering across software, infrastructure and connected devices.

I work across the complete delivery path: product structure, Python backends, APIs, databases, Linux servers, automation, integrations and device communication. The goal is a reliable production system that is practical to operate, maintain and extend.

01 // Backend engineeringPython, Django, Flask and FastAPI for business logic, APIs, authentication, admin tools and background processing.
02 // Systems integrationREST APIs, webhooks, data synchronization and third-party services connected into dependable workflows.
03 // DevOps & infrastructureLinux servers, Nginx/Apache, SSL, reverse proxy, systemd, deployment, monitoring, backups and troubleshooting.
04 // Hardware & protocolsRS-232, TTL, IoT and SAS communication for projects that connect software with physical devices.

Architecture that connects frontend, backend, servers and devices.

I design systems as complete architectures — from the user interface and API layer to application logic, databases, deployment and hardware communication. This is especially useful for SaaS, operational platforms and custom integrations.

System architecture

Experience connecting client-facing applications with APIs, Python services, relational databases, production servers and device protocols in one end-to-end system.

Production engineering

Hands-on work with Python services, Linux deployment, database migrations, service health checks, serial communication and production troubleshooting.

Engineering skills across the whole product stack.

From product UX and backend APIs to deployment, databases, automation and device protocols — the focus is on complete, maintainable systems rather than isolated pages.

Websites & apps

Modern business sites, admin panels, portals and full-stack apps with clean architecture and fast UX.

DjangoFlaskGo

E-commerce

WooCommerce / Shopify integrations, product import flows, payment logic and price tracking.

WooStripeTracker

Automations

Scripts, dashboard tools, scheduled jobs and API glue that eliminate repetitive manual work.

CronAPIsAgents

Hardware integrations

Serial communication, RS-232, protocol work and real-time devices where standard sites are not enough.

RS-232SASIoT

APIs & integrations

REST APIs, webhooks, third-party services, imports/exports and reliable system-to-system synchronization.

FastAPIRESTWebhooks

Linux & deployment

VPS administration, systemd services, Nginx/Apache, SSL, reverse proxy, logs, backups and production troubleshooting.

AlmaLinuxNginxsystemd

Data & databases

Relational models, migrations, reporting, dashboards, background jobs, caching and operational history.

MariaDBMySQLRedis

AI-assisted engineering

Modern AI-assisted workflows for faster prototyping, refactoring, documentation, testing and maintenance.

services_runtime.log

Core technical capabilities

Full-stack development, API integration, automation, Linux infrastructure, databases, e-commerce workflows and hardware communication — with focus on stable production use.

Selected products and active systems.

Production work spans SaaS, internal tools, PWA utilities, e-commerce, HR/ERP, price tracking and newer platforms such as VG Pass, Tree and AI learning systems.

From idea to production, with a practical engineering process.

I work from requirements and architecture through implementation, testing, deployment and support, keeping the solution understandable, maintainable and ready for real-world use.

Discover

Short brief, goals, constraints and the reality behind the request.

Design & structure

Information architecture, stack choice, data flow and UI direction.

Build & test

Iterative development with previews, fixes and performance/security checks.

Launch & support

Deployment, monitoring, documentation and stable handover.

pipeline.sh

Deployment & support

Production deployment, service checks, logs, monitoring, backups, troubleshooting and clear handover are part of the delivery — not an afterthought.

Practical engineering across software, infrastructure and devices.

I combine application development with server administration, automation, databases and hardware integration, which lets me handle projects that require more than a standard website or isolated application.

Backend & APIs

Python, Django, Flask, FastAPI, REST APIs, webhooks, authentication, role-based permissions and background jobs

Frontend & product UX

Responsive HTML/CSS/JavaScript, component-driven UI, PWA flows, dashboards and mobile-first interfaces

Data layer

MariaDB, MySQL, SQLAlchemy, Alembic, Redis, imports/exports, reporting, search, history and analytics

Infrastructure & DevOps

AlmaLinux, CentOS, Ubuntu, Debian, CWP, Nginx/Apache, SSL, reverse proxy, systemd, Docker/Podman, DNS, firewalls, backups and monitoring

Hardware & protocols

RS-232, TTL, serial communication, Arduino/ESP-class devices, IoT, SAS protocol work and server-to-device integration

Engineering workflow

Git, VS Code, remote server administration, AI-assisted coding, debugging, documentation, staged deployment and production support
