For HR and IT teams
A developer who can join product work, understand tasks quickly, communicate clearly and ship iOS/backend features without drama.
IT / Mobile / Backend / IoT
Kostiantyn Volkov - practical engineer for apps, automation and connected systems
I help companies and founders build the thing they actually need: an iOS app, a backend, an admin panel, an AI workflow, an IoT dashboard, or a small production system that simply works.
Who it is for
I explain technical decisions in plain language, keep the scope visible, and show progress with working demos instead of long abstract reports.
A developer who can join product work, understand tasks quickly, communicate clearly and ship iOS/backend features without drama.
You do not need to know the stack. Tell me what should happen in the business, and I translate it into a practical technical plan.
Sensors, ESP32/Raspberry Pi, dashboards, alerts, device data, local network tools and mobile control interfaces.
What I can build
Not “I know many technologies”, but “I can connect the pieces into one usable system”.
iOS apps, SwiftUI/UIKit interfaces, subscriptions, push notifications, offline mode, analytics and App Store release.
FastAPI services, PostgreSQL, Redis, auth, admin panels, payments, background jobs and stable Docker deployments.
ESP32, USB/serial devices, cameras, local servers, dashboards, device monitoring, alerts and integrations with real hardware.
OpenAI/Gemini workflows, OCR, voice, content pipelines, Telegram bots, CRM helpers and small automations that save manual work.
Performance, bugs, server setup, Docker, Nginx, monitoring, migrations, admin tooling and support after launch.
Architecture, task breakdown, feasibility checks, estimates and plain-language explanations before development starts.
How we work
What should the user or business be able to do when the work is finished?
No overengineering. I explain the stack, risks and timeline in normal words.
Small releases, clear feedback, real testing, deployment and support.
Experience
Midnight.Works / Remote
Production SwiftUI work under NDA: modular architecture, navigation flows, API integration, caching, pagination and analytics.
Polorix / Remote
End-to-end product work across iOS, backend, AI/content pipelines, recommendations, translations, admin notifications and deployment.
Self-employed / Remote
Apps with onboarding, auth, subscriptions, push notifications, offline caching, widgets, reports and App Store releases.
Proof of work
The useful pattern: mobile UI, backend logic, data, automation and deployment working together.
SwiftUI app with offline cache, REST APIs, RevenueCat, analytics, APNS, recommendations, reviews, collections, quotas and admin tooling.
FastAPI pipeline for ingestion, AI enrichment, OCR, media processing, scheduled sync and provider integrations.
Network utility with diagnostics, device discovery, port scans, reports, subscriptions and analytics.
Self-hosted services, Nginx routing, Docker Compose, status dashboards, protected admin panels, maps, voice, backups and automation.
Stack
Next step
A short message is enough: what you want to build, what already exists, what is broken, and what deadline matters.
