Thai Binh, Vietnam
$20 USD per hour
I am a multidisciplinary engineer specializing in the integration of mechanical design, electronics, and software development to deliver complete, real-world engineering solutions. With a strong foundation across these domains, I bring a systems-level perspective that allows me to design, prototype, and implement projects from concept to deployment. On the mechanical side, I have extensive experience in CAD design, product development, and manufacturing-ready solutions. I focus on creating efficient, practical designs that consider real-world constraints such as materials, fabrication methods, and cost optimization. In electronics, I work with embedded systems, PCB design, and hardware integration. I am comfortable developing schematics, selecting components, and ensuring reliable communication between hardware and control systems. On the software side, I develop firmware and control logic for embedded devices, as well as higher-level applications for automation, data acquisition, and system monitoring. I have experience working with microcontrollers, PLCs, and industrial communication protocols, enabling seamless integration between hardware and software systems. What sets me apart is my ability to bridge these disciplines. Instead of treating mechanical, electrical, and software components separately, I design them as a unified system—resulting in more robust, efficient, and scalable solutions. I have worked on projects ranging from industrial automation and embedded systems to custom machinery and prototyping. I collaborate effectively with cross-functional teams, including mechanical engineers, electrical engineers, and software developers, ensuring smooth communication and successful project delivery. If you are looking for someone who can take ownership of a project end-to-end, reduce complexity, and deliver practical engineering solutions, I would be glad to help bring your ideas to life.

I have 15 years experience of PCB and antenna design using Cadsoft Eagle, OrCAD, MATLAB, ADS, AWR, CST and HFSS. I have designed many circuits for mixed-signal applications. I am also expert in HFSS / CST and ADS / AWR for RF and Microwave applications specially antennas.
A Radio Frequency Engineer designs, tests, and optimizes wireless systems and circuits that transmit and receive signals across the RF spectrum, from a few kilohertz up to millimeter-wave frequencies. Hiring a freelance Radio Frequency Engineer gives you direct access to specialist expertise in antenna design, RF circuit development, link budget analysis, and wireless compliance testing without committing to a full-time hire. Whether you are building an IoT product, a 5G small cell, a satellite payload, or a Wi-Fi router, an experienced RF engineer turns abstract wireless requirements into hardware that actually works in the real world.
RF engineering sits at the intersection of electromagnetics, analog circuit design, and digital communications. A capable RF specialist can take a project from concept through schematic capture, PCB layout, prototype bring-up, and regulatory certification. The commercial value is direct: better range, lower power consumption, cleaner spectrum, and products that pass FCC, CE, or ETSI testing on the first attempt.
Typical deliverables from a freelance RF consultant include:
Look for hands-on experience with the simulation, measurement, and design tools that define modern RF work. Strong candidates name specific software and instruments rather than speaking in generalities.
RF expertise is in demand wherever wireless connectivity is a product feature or core infrastructure. Common engagements come from:
RF is a discipline where mistakes are expensive, so qualifications matter. Look for a degree in electrical engineering or electromagnetics, ideally at the graduate level, and a portfolio that shows real measured results rather than only simulation screenshots. Strong signals include published return loss and radiation pattern plots, certification reports, and references to specific transceiver chipsets the engineer has worked with.
Useful interview questions to copy and use:
Freelancer.com gives you access to a global pool of RF specialists, antenna designers, and wireless systems engineers across every major time zone and frequency band. You can post a project on Freelancer.com and receive competitive bids within hours from engineers who have shipped IoT modules, deployed cellular networks, and certified consumer hardware. Profiles include verified skill tests, portfolio samples, and client reviews so you can judge experience before committing. Clients set their own budgets, and Milestone Payments hold funds securely until each deliverable is approved, which protects both sides on highly technical engagements.
Ready to build, debug, or certify your wireless product with expert help?
Hiring an RF engineer works best when you treat the brief as a technical specification. The clearer you are about frequency band, target standard, and deliverable format, the more accurate the bids you receive will be. Here is the process from project post to award.
Your project description is the single biggest factor in bid quality. RF is a wide field, so a vague brief attracts mismatched candidates while a precise brief filters for engineers who genuinely know your frequency band, standard, and toolchain. Head to the
Bids on RF projects are mini technical proposals. A strong bid shows that the engineer has read the brief, understood the wireless standard involved, and can articulate a credible approach within the first few sentences. Read each proposal closely rather than sorting purely by price, and use Freelancer.com's chat to ask clarifying questions before shortlisting.
Final selection should weigh proposal quality alongside profile evidence. RF work rewards consistency, so look for engineers whose track record shows repeat success across similar projects rather than a single impressive job. Portfolio depth, written reviews, and verified credentials all matter.
A focused antenna tuning or matching network design can be completed in one to two weeks, while a full RF front-end design with PCB layout, prototyping, and pre-compliance testing usually runs eight to sixteen weeks. Timelines depend on board complexity, frequency band, and whether the design must pass formal certification.
Yes. Many clients engage freelancers on Freelancer.com for design reviews, schematic audits, layout checks, or troubleshooting a single failing test. This is a cost-effective way to catch issues before fabrication or before sending a product to a certification lab.
An RF engineer focuses on the physical layer: circuits, antennas, propagation, and analog signals. A wireless software engineer works on protocol stacks, drivers, and application-layer code that runs on top of the radio. Complex products often need both, but they are distinct roles with different toolsets.
For discrete tasks such as antenna design, link budget analysis, or compliance pre-scans, a freelancer is faster and more flexible. For end-to-end product development with mechanical, firmware, and manufacturing integration, you may want a small team, which you can also assemble through Freelancer.com by hiring complementary specialists.
Experienced RF freelancers regularly handle pre-compliance testing, prepare test reports, and liaise with certification labs for FCC, CE, IC, and ETSI submissions. They cannot issue certifications themselves, but they significantly reduce the risk and cost of formal testing.
