Inside WizzDev’s Engineering Workflow: How We Deliver Embedded Projects with Clarity and Precision

At WizzDev, we manage embedded software and hardware projects with structure, clarity, and full accountability. Our goal isn’t to sell partnerships or make big promises — it’s to deliver reliable, measurable results through a repeatable process that our clients can trust.

Whether you’re a product manager at a medtech company, an engineering lead building smart building systems, or an innovator in the IoT space, this page will give you a clear picture of how we work and what you can expect when we manage your project.

Who We Work With

At WizzDev, we serve a wide range of industries where precision engineering, regulatory compliance, and system integration are essential. Our clients rely on us not just for technical execution but for our ability to fully understand their constraints, user needs, and long-term product goals. Below are the core client categories we work with:

Medical Device Teams

We regularly support teams building embedded systems for regulated healthcare products. These projects demand absolute precision, stable firmware, and thorough documentation to meet compliance standards like FDA and CE. Whether it’s a wearable health tracker, patient monitoring equipment, or a Bluetooth-enabled diagnostics device, we understand the stakes and know how to build for them.

Smart City and Building Innovators

Our experience with connected infrastructure includes work on sensor networks, access control systems, environmental monitoring, and smart energy management. These projects often require long-term scalability, wireless integration, and robust backend communication — all of which we handle in-house.

IoT Platform Developers

From consumer gadgets like smart thermostats and home security devices to industrial control systems and remote telemetry hardware, we support teams creating IoT ecosystems. We design and implement the embedded code, cloud integration, and user interfaces required to bring a full-stack IoT product to life.

R&D and Innovation Teams

Whether you’re in a startup, corporate innovation lab, or university research setting, we offer technical muscle for when your internal team needs support. Our R&D clients often rely on us for rapid prototyping, feasibility testing, and proof-of-concept development under tight timelines.

Common Project Types

The kinds of projects we deliver span a wide technical spectrum, including:

  • Embedded firmware for ARM Cortex-M devices, ESP32, Nordic chips, and more
  • Microcontroller programming in C++, Python, and mixed-language environments
  • End-to-end cloud integration using AWS IoT Core or Azure IoT Hub
  • Dashboard and UI development for device control and visualization
  • Custom PCB design, hardware prototyping, and pre-certification builds

All development takes place entirely in-house at our Poznań, Poland office. We do not outsource or delegate to freelancers. Every project is executed by our own engineering team, ensuring full accountability, clear communication, and consistent quality from start to finish.

Our Process: End-to-End Project Execution You Can Track

Step 1: Understanding What You Need

The first step is simple: we ask questions and listen. Our job is to understand your idea, the problem you’re solving, and the constraints you’re operating under — timeline, budget, compliance, end-user expectations.

We turn that into a Technical Proposal, which includes:

  • A breakdown of the work in milestones
  • Estimated hours per milestone
  • Potential risks or blockers
  • Initial hardware assumptions if applicable

We’ll sign your NDA (or offer ours) before you share anything confidential.

Step 2: Defining the Work and Budget

Once you approve the technical approach, we prepare a Commercial Proposal that lays out:

  • Hourly rates per role (developer, tester, tech lead)
  • Milestone-based budgeting
  • Payment model (time & materials or fixed)
  • Licensing and IP rights

If you’re happy with the proposal, we sign two things:

  • MSA (Master Services Agreement) — the legal framework
  • SOW (Scope of Work) — the scope, timeline, and deliverables

We don’t start until everyone is on the same page.

Step 3: Executing the Project — with Complete Visibility

Once we begin, you’re never in the dark. Here’s how we keep you updated:

  • We track time using Zistemo, broken down by task
  • All work is planned and tracked in Jira, with access on request
  • Regular updates show what’s done, what’s active, and what’s next
  • Invoices are issued through Nexo, tied directly to tracked hours

Whether you prefer async updates, milestone summaries, or weekly calls, we match your pace and communication style.

Step 4: Delivering What We Promised — With Proof

We deliver working code and hardware, not vague reports. At every major milestone, we provide:

  • A demo video or live walkthrough
  • Firmware binaries and source code
  • Setup instructions and documentation
  • Time reports and completion summaries

We wrap each project with a structured hand-off and feedback review.

Technologies and Tools We Use

We maintain a deep, up-to-date skill set across embedded and full-stack technologies.

  • Languages: C++, Python, Java
  • MCUs: STM32, ESP32, Nordic, Microchip
  • Cloud platforms: AWS IoT Core, Azure IoT Hub, MQTT brokers
  • Frontends: React, Flutter
  • Hardware design: Altium, KiCad, 3D enclosures, PCB prototypes

We work efficiently because we’ve done this before — many times.

Why Our Clients Trust Our Process

When clients choose WizzDev, they’re not just hiring an engineering vendor — they’re gaining a disciplined, dependable system that consistently delivers real outcomes. Here’s what sets our approach apart:

Clear tracking of time, progress, and budget

From day one, we provide full visibility into what’s being worked on, how much time has been spent, and how it aligns with your allocated budget. Tools like Zistemo and Jira ensure everything is logged and accessible, so you’re never guessing where your resources are going.

Consistent structure, from proposal to final delivery

We don’t improvise project structure as we go. Every engagement follows the same logical progression: technical proposal, commercial proposal, contracts, execution, and hand-off. That structure means fewer surprises, better forecasting, and smoother collaboration.

Deep embedded systems knowledge across industries

Our team brings experience from over 100 real-world projects across healthcare, smart buildings, industrial IoT, and consumer electronics. We know how to write low-level firmware, build cloud APIs, and design hardware that’s production-ready. This expertise helps us spot problems early, make better technical decisions, and deliver more stable solutions.

We don’t deliver until it works, is documented, and is traceable

Our definition of “done” includes tested firmware, version-controlled code, setup documentation, and full time accounting. We don’t disappear after we send a ZIP file — we ensure the handoff is thorough, clean, and ready for real-world use.

Unlike agencies that focus on planning workshops or strategy consulting, we’re focused on building things that work. We don’t sell strategy sessions. We deliver working embedded systems, reliably and transparently — the way engineering should be.
