High Tech Engineering Center d.o.o.

Production and maintenance consulting and support

We work together with clients, production, and delivery parties to organize and optimize product manufacturing and commissioning processes.

Our experience covers:

• development of dedicated hardware testing and verification utilities for product manufacturing support;
• implementation of software tools used for tracking the production and assembling information for traceability and maintenance purposes.

Products certification support

Depending on the product type and associated industry, we can support our clients with information about the certification procedures and required compliance standards through the network of our certification partners in Europe and the USA.

We proved the service of the development of dedicated software, hardware, and firmware documentation that is used in the certification process for validating specific device characteristics.

We also provide product design review and tuning, to comply with a certain standard and compliance validation in unofficial precheck testing sessions.

General consulting services

We can help clients to improve product design and quality by hiring us strictly as consultants, without working on the development of a product.

Our senior engineer and consultants can analyze potential issues from both tech and usability perspective, employing their technology know-how and accumulated experience. We can provide various technical solutions and design approaches that can be implemented with detailed information about the merits and disadvantages, working with the client on selecting options that are the best trade-off for the product in terms of price, development effort, maintainability, scalability, and flexibility.

With our proactive participation in the product design and features definition, we can bring the start-up projects and ideas to the production-grade product level.

Embedded Software Development

The services HTEC provides in this area are:

• Implementation of high-quality firmware, real-time and system software based on experience with various technologies, programming languages, and platforms;
• Ensuring code and delivery quality by utilizing utilities and methodologies for firmware and software validation and verification;
• Managing controlling and communicating transparently through the whole development process through all phases of the development with maximum progress traceability;

Our project implementation scope is broad and contains system and software architecture design, modules and components development and integration, low-level programming, legacy code maintenance, refactoring and improvements, unit and integration tests.

All of our software and firmware quality metrics relate to strict qualification and certification standards that ensure maximum reliability, maintainability, and performance.

Hardware Development

We provide the design and development of high-quality hardware, based on experience with various technologies. Our complete design and development relate on strict standards that guarantee maximum reliability and performances. The customer requirements and specifications are converted into functional block diagram, circuit schematic, and printed circuit board layout. Component selection and purchasing are maximally optimized and fully traceable by using our developed in house component database and verified procurement solutions.

Our services in this area include:

• Complete system design phase;
• Schematic capture and PCB design aligned with casing mechanics;
• Rapid prototyping;
• DFM analysis;
• Preparation for mass production;
• Quality assurance procedures.

Our service is dynamically organized and adjusted for each customer to get both rapid prototyping and cost-optimized design ready for small series production in a reasonable time frame. In order to support volume production, HTEC offers DFM analysis, cost reduction analysis, and quality assurance procedures. Each design can be supported with customized test environments and test suites for mass production lines.

Code Porting and Optimization

Our team has vast experience in implementing software libraries for complex processing functions that are optimized for a particular hardware platform or programming language. Target platform can be a specific CPU or DSP, whereas the maximum performance is achieved by utilizing computing core hardware and assembly codding idioms.

We also offer development C/C++ SDK or libraries and documentation from PoC or research-grade code developed in Python, Matlab, or other programming languages. Ported code provides the same or similar outputs and results accuracy, but with minimum resources required and the ability to run on dedicated embedded hardware.

Technologies:

• Programming languages and toolchains: C, C++, C#, Java, Go, Assembly, Python, Matlab, GCC, MinGW, LLVM
• CPU architectures: MIPS 32/64. NANOMIPS, PowerPC 32/64, X86, ARM 32/64

HTEC has a Machine Learning team that can provide complementary services to hardware and embedded software development. Our team can develop a project-specific system for model evaluation that contains data collecting hardware and firmware for a specific domain.

We have experience in evaluating and training Machine Learning networks, which create the models that provide accepted accuracy and sensitivity and that are portable to the edge hardware. Our processing sensors data streams use the DSP algorithms to optimize ML engine performance and hardware requirements.

Our Project/Product Managers have experience in selecting the proper project implementation flow that provides the best delivery for a specific project type, requirements, budget, and timeline.

We always do the estimation of the required resources for all project phases, in terms of development effort and implementation costs, with maximum transparency and flexibility towards the client.

Part of our process is continual project scoping, verification, and progress tracking based on Scrum, Kanban, or other projects specific appropriate agile methodology. That allows us perfect synchronization of heterogeneous tech teams, stakeholders, and any third parties.

Solution Providing and System Integration

Services we provide in this area:

• Research and selection of technologies and solutions that are suitable for system components implementation;
• Development or integration of existing hardware and software components for the current system according to the requirements.

Our expertise covers all technology stacks that are required for a product design and implementation: embedded systems design, web development, Mobile development (iOS/Android), Data Science and Machine Learning, DevOps engineering, and infrastructure maintenance.

Rapid Prototyping

Product development and design we do are based on accumulated experience and know-how with a high level of hardware and software reusability. It ensures extremely fast delivery cycles for the initial prototypes and proof of the concept designs for our clients.

Our coherent and agile team of engineers and developers tightly collaborate with an always clear focus on the results and early delivery.

We utilize PCBA and EMS partners services, 3D printing capabilities, and third-party or Open Source software components and libraries to coordinate hardware, firmware, and mechanical design activities.

Product Retrofitting

Apart from designing and developing new products and systems with new technologies and solutions, our services also include products retrofitting and thus extending the product lifecycle.

Our services include:

• Extending the product lifecycle with maintenance and production cost reduction;
• Improving product integrability with other system components devices and services: IoT platforms, enterprise information systems, Smartphone devices, and other devices;
• Migrating project firmware to another SoC/MCU platform and implementing drivers and modules for new hardware;
