Hire the Best Wireless Freelancers
in the United States

Holds a PhD in Computer Science (Ghent University) focusing on optimization of wireless systems and AI/ML. Experienced in design and optimization of wireless systems (4G/5G (3GPP), Wi-Fi(IEEE 802.11), software-defined radio systems, digital signal processing, algorithm development, AI model training, data analysis, and project management. Skilled in Python, C/C++, and TensorFlow, with hands-on expertise in automation, technical tool development, and machine learning applications. Proven ability to contribute to interdisciplinary research projects, develop scalable software solutions, and work with diverse teams across academia and industry. Experienced in creating technical documentation, performance analysis tools, and training content for AI platforms. Strong background in system integration, scripting, and experiment-driven problem solving. Proficient in Machine Learning/AI, Python, and C/C++. # What I do: • Wireless systems & DSP: link- and system-level modeling, PHY/MAC algorithm design, KPI analysis (RSRP/RSRQ/SINR, latency, throughput), coverage/heatmap tooling, performance evaluation. • SDR prototyping: end-to-end builds with USRP/FPGA; experiments on srsRAN, OpenAirInterface. • AI/ML for comms: feature engineering (FFT/IQ pipelines), classification models, federated/reinforcement learning, model training/evaluation in TensorFlow & PyTorch. • Automation & data tooling: Python pipelines for data labeling, parsing, and visualization (e.g., Grafana), experiment orchestration, and reproducible research assets. • Technical content: research-grade writing, specs, API docs, tutorials, grant proposals, MCQs/exams, and training content for AI platforms. # Selected outcomes: • ML-based preprocessing for signal-type identification that improved classification accuracy (FFT-driven pipeline in Python/TensorFlow). • Federated learning–based spectrum sensing that dramatically reduced data transfer needs during training while maintaining model performance (PyTorch). • Dynamic spectrum-sharing research across 4G/5G that increased spectrum-utilization efficiency, validated via simulation and analysis. • Robust post-processing/visualization tools for drive-test data, enabling faster KPI reporting and decision-making. # Technical content & documentation: • Experienced technical content writer with a strong background in implementing solutions and producing detailed reports for large-scale research initiatives. • Skilled in authoring original research articles, technical documentation, grant proposals, and in disseminating scientific findings. • Comfortable translating complex DSP/communications and AI concepts into clear, accurate materials for engineers, researchers, and non-technical stakeholders alike. # Toolbox: • Python, C/C++, MATLAB • TensorFlow, PyTorch • Linux, shell scripting, Git • SDR (USRP), FPGA integration • srsRAN, OpenAirInterface, openwifi • Grafana • Data labeling/QA workflows # Collaboration: I’m available for consulting, scoped research/prototyping, algorithm development, KPI analysis/reporting, automation tooling, and technical writing.

I have years of experience designing, deploying, and managing networks for small and medium businesses. I can provide one-time or ongoing services for your business. I have extensive experience with Ubiquiti (Unifi & UISP), Cisco/Meraki, Watchguard, and Sonicwall technologies. I work well independently, or can also work collaboratively with internal IT teams, contractors or service providers.

Stop relying on automated scans. I find the vulnerabilities they miss. I’m a senior penetration tester and vulnerability researcher with deep experience across enterprise networks, web apps / APIs and cloud platforms. Most testers just run automated tools and hand you a generic report. I simulate how an attacker actually thinks, perform thorough testing, and deliver professional, tailored reporting suitable not just for your own remediation efforts but also for audit / compliance. Benefits of manual testing: - Chaining multiple low/medium findings to show more significant impact - Breaking multi-tenant isolation - Bypassing auth controls (JWT, OAuth, misconfigurations) - Identifying cost-amplification / abuse vectors (e.g., billing attacks in serverless environments) - ZERO false positives (and wasted time trying to remediate non-issues) - REAL severity scoring (not just CVSS or ratings with no connection to actual impact/risk for your systems and data) What I Deliver - Manual, attacker-style testing (not just scans) - Clear, prioritized findings with real business impact - Proof-of-concept exploits where it matters - Practical remediation guidance your devs can use immediately - Optional retesting to verify fixes Common Engagements - SaaS / multi-tenant application security testing - API and authentication testing (JWT, OAuth, session flaws) - Cloud security reviews (GCP, AWS, Azure, O365) - DevOps security reviews (Gitlab/hub, BitBucket, etc.) - Pre-SOC2 / investor readiness assessments - High-intensity black-box pentests Why Clients Hire Me - I go beyond the scan—I find what others miss - I understand both offense and architecture - I communicate clearly with both engineers and leadership - I’ve worked on MANY real-world, high-impact systems I also help organizations: - Investigate breaches - Contain active threats - Recover compromised systems (Note: I do not assist with social media account recovery.)
