No ready specification needed. Start by describing the task.

What we do

Services

Five directions of the offer. They describe what we take on, not a finished public case for every sub-task: each card shows the confirmed examples.

Websites, apps and online services

Client portals, internal systems, mobile and desktop apps, and the server side behind them.

Typical tasks

  • A web service or client portal with accounts and an admin panel
  • An internal tool for your team instead of spreadsheets and chats
  • A backend and API for a mobile or desktop app

Result: A working service that people use: interface, server side and deployment.

Examples: Industrial Atlas — interactive globe (Own product); Site Agent — AI support platform (Own product)

Technologies and evidence

Technologies: ASP.NET Core 8, Node.js, PostgreSQL, SignalR and WebSockets, React and plain JavaScript, PWA, Linux servers with nginx.

Evidence: Working public examples: our own products Industrial Atlas, Site Agent and PartySound, and a ticketing platform built for an event organizer.

Discuss a task

Automation, AI and integrations

Documents, data, repetitive processes, bots and connecting systems.

Typical tasks

  • Process incoming documents and spreadsheets automatically: import, checks, reports
  • An AI assistant that answers from your own content and hands the conversation to a person
  • A Telegram bot or an integration that removes manual copying between systems

Result: An automated process or assistant built into your work, with decisions left to a person where they matter.

Examples: Site Agent — AI support platform (Own product); Document and data automation (under NDA) (Employment under NDA)

Technologies and evidence

Technologies: C#/.NET, Node.js, OpenAI API, answers from your own documents (RAG), Excel and Word processing, Telegram Bot API, REST integrations.

Evidence: Site Agent, our own AI support platform, runs as a public demo. Document automation was done as an employee under NDA, so it has no public demo. The InNews news bot is paused.

Discuss a task

Interactive 3D

Demonstrations, configurators, instructions and equipment presentations.

Typical tasks

  • Show a product, a place or data as interactive 3D in the browser
  • A step-by-step 3D instruction or a presentation of equipment
  • Make a heavy 3D scene load quickly and run on ordinary laptops and phones

Result: A 3D scene that opens by a link, without installing anything, and explains the product or data visually.

Examples: Industrial Atlas — interactive globe (Own product); StreamForge — fast loading of heavy 3D on the web (Own tech demo)

Technologies and evidence

Technologies: three.js and WebGL, globe.gl, our StreamForge chunked loading, Unity WebGL, glTF pipelines.

Evidence: Public examples: the Industrial Atlas globe and our StreamForge tech demos. Configurators and equipment presentations have no public case yet; such a task can be discussed.

Discuss a task

Games, VR and simulators

Mechanics, training, simulators, porting and optimisation.

Typical tasks

  • Game mechanics, multiplayer or a playable prototype
  • A VR training scenario or a simulator
  • Update an existing Unity project, port it to another platform or headset and improve performance

Result: A build that runs on the target devices, handed over to you or prepared for store submission.

Examples: TimeLock VR 2 (Work for a publisher); We Are The Dwarves — 2026 update (Client work for a publisher)

Technologies and evidence

Technologies: Unity (URP, HDRP), C#, OpenXR, Meta Quest, SteamVR, Mirror and Photon networking, Steamworks, Epic Online Services.

Evidence: Work on games of publisher Whale Rock Games: the Steam release and GOG port of TimeLock VR 2, 2026 updates of We Are The Dwarves and Deployment (their release is up to the publisher), support of TimeLock VR 1 and two games in development. Also VR rehabilitation work at Advin and our own VR prototypes. Each case states our exact role.

Discuss a task

Software for hardware

Control interfaces, sensors, controllers, data exchange and prototypes.

Typical tasks

  • A control or monitoring interface for a device
  • Reading sensors and exchanging data with a microcontroller (Arduino, ESP32, serial port)
  • A prototype that connects hardware with an app or a 3D/VR scene

Result: A working prototype or interface for your device; feasibility is assessed per task.

Example: MechaLearn — robotics learning in VR and on the web (Own prototype)

To be honest: there is no public shipped product yet that controls real hardware. The closest example is MechaLearn, a prototype with emulated Arduino boards (Uno, Mega, Nano); Vadym also taught Arduino robotics to children. A hardware task can be discussed, and feasibility is assessed separately.

Technologies and evidence

Technologies: C# with serial port communication, Arduino, ESP32, Raspberry Pi, I2C, SPI, UART, PWM and ADC, Unity.

Evidence: To be honest: there is no public shipped product yet that controls real hardware. The closest example is MechaLearn, a prototype with emulated Arduino boards (Uno, Mega, Nano); Vadym also taught Arduino robotics to children. A hardware task can be discussed, and feasibility is assessed separately.

Tell us about it

Formats

Ways to work together

Independent of the direction: build something new, improve what already exists, or first sort out a question.

Build from scratch

You have an idea or a task but no solution yet. We work out what must work and for whom, agree on a first version and build it.

Discuss a new project

Improve or optimise

You already have a product, website, game or Unity project. We add features, fix problems, update the engine or libraries, port it to new platforms or make it faster.

Discuss an improvement

Sort it out in a consultation

You are not ready to order development and want to understand a technical question first. After a consultation you are not obliged to order anything.

Discuss a consultation

Consulting

Technical consultations

You can order implementation, or you can first sort out a technical question. A consultation is a separate request, not a mandatory step before development. What you get is agreed per question.

Questions you can bring

  • Is the idea feasible?

    We look at whether the idea can be built with available technology, what the main risks are and what to check first.

  • Architecture and technology choice

    We compare options for the architecture, stack and services for your task and explain the trade-offs.

  • MVP plan

    We help decide what goes into the first version, what can wait and in what order to build.

  • Review of an existing project

    We look at an existing project, how it is built and where it is weak, within the scope agreed for your question. A full code audit is not possible from a short description.

  • Performance

    Slow loading, low frame rate, heavy scenes or overloaded servers: we look for likely causes and ways to measure and fix them.

  • Integration

    Connecting systems, services, bots or devices: we discuss options, data exchange and pitfalls.

What you can get, agreed per question

  • Recommendations on your question
  • Options with their constraints
  • A list of risks
  • A plan of next steps

A consultation does not oblige you to order development.

Format, cost and duration are agreed after we look at your question.

Process

How we work

  1. Describe the task

    Use the form, the chat, or write directly by email or Telegram. No ready specification is needed: a few sentences about what should work and for whom are enough to start.

  2. We clarify the details

    Vadym reads the request and asks only what affects the next step: a new or existing solution, platforms, constraints, materials.

  3. We agree on the next step

    Depending on the task, this is a consultation, an estimate, a prototype or development. Format, cost and timing are agreed individually before any work starts.

About

Who does the work

Vadym Khavronenko runs InPower and does the technical work himself. “We” on this site is the brand voice: InPower does not claim a large team.

On publisher projects, art, game design, writing and QA were done by other people on the studio's side or by specialists hired for the project; each case states Vadym's exact role.

Location: Da Nang, Vietnam (UTC+7), remote
Languages: English, Russian, Ukrainian
