Hire the Best VOIP Software Engineers
in Kenya

I design, build, and run carrier-grade telephony and systems infrastructure — SIP interconnect, SBC platforms, IVR, call centre systems, and the security/identity layer underneath them. Over 18 years, this has included co-founding a Class 5 VoIP network from zero, designing a multi-tenant Session Border Controller bridging carrier IMS/VoLTE to three tenant systems, containing a live SIP toll-fraud attack with zero customer disruption, and building a Python/AGI IVR with real-time outage detection running across five East African countries. I've managed direct SIP trunk relationships with five national carriers (Safaricom, Airtel, MTN, Vodacom, TNM) and administered enterprise Active Directory, OpenVPN/FreeRADIUS, and remote-access security across multi-country operations. What I can help with: Asterisk / FreeSWITCH / VICIdial deployment, tuning, and troubleshooting SIP trunk setup, carrier interconnect, and fault diagnosis SBC design and configuration (IMS/VoLTE bridging, multi-tenant) IVR and call centre platform builds (AGI/AMI scripting, Python/Flask tooling) Toll-fraud incident response and hardening Active Directory, VPN, and network security administration I work directly and communicate plainly — clear scope, realistic timelines, no overselling what a fix will take.

I am a Senior Engineer with strong expertise in AWS, Google Cloud Platform, Linux systems, automation, and network/security engineering. I help businesses design, deploy, secure, and automate scalable infrastructure, on-prem, cloud, and hybrid environments. On the DevOps side, I specialize in: CI/CD pipelines using Jenkins, Git, and cloud-native CI/CD platforms Containerization & orchestration with Docker and Kubernetes Infrastructure as Code (IaC) using Terraform and Ansible Deployment automation for cloud and on-prem environments Linux system administration (Ubuntu & enterprise Linux) Scripting and automation using Python, Bash, and Git On the Cloud & Architecture side, I work extensively with: Amazon Web Services (AWS) – EC2, networking, security, and automation Google Cloud Platform (GCP) – Cloud Run and cloud-native services Cloud architecture design, optimization, and cost-efficient scaling Secure, highly available, and production-ready cloud environments I also bring deep expertise in Networking and Security, including: Firewall deployment & management (FortiGate, Fortinet, Palo Alto, Juniper, Cisco, UniFi) VPN technologies (IPsec, SSL VPN, FortiClient) Routing & switching – BGP, OSPF, ECMP, VRF, VXLAN ISP & enterprise networking – Peering, IP Transit, IXP sites Cisco & Juniper networking environments Network security, firewall policies, and security infrastructure hardening Additional strengths include: Windows Server & Active Directory administration IPv4/IPv6, VLANs, SSL, VoIP fundamentals Troubleshooting complex production issues Technical support and system configuration in enterprise environments I am detail-oriented, automation-driven, and security-focused, with real-world experience supporting mission-critical systems. Whether you need cloud migration, DevOps automation, CI/CD setup, Kubernetes deployments, firewall/VPN configuration, or network optimization, I deliver reliable, scalable, and well-documented solutions.

I build and automate business phone systems: 3CX, Twilio, SIP trunking, CRM integrations, and AI voice agents that connect to real phone lines. Most freelancers can install a PBX. I run them for a living. I manage the telecom infrastructure of an ISV serving multiple client companies on Twilio and 3CX, and I wrote the tooling that automates our onboarding: subaccount creation, number purchasing, and trunk configuration in minutes instead of hours. WHAT I DO ☎ 3CX (V20) • New deployments (cloud or on-prem), V18 to V20 migrations, SBC configuration • Multi-tenant setups for MSPs, with tenants provisioned programmatically through the 3CX Configuration API (XAPI) • Call Flow Designer apps: IVRs, mid-call CRM lookups, scheduled callbacks, caller authentication, VIP routing • CRM integration: first-party (HubSpot, Salesforce, Zoho, Dynamics, Freshdesk, Zendesk) and custom REST templates for any CRM with an API 🔌 Twilio / Telnyx / Vonage • Elastic SIP trunking into 3CX or any PBX • Programmable Voice and Messaging: IVRs, campaign dialers, appointment reminders, click-to-call • A2P 10DLC registration and regulatory bundles for international numbers • Subaccount and number-provisioning automation for agencies and ISVs 🤖 AI voice agents (Vapi / Retell / ElevenLabs) • The part most builders get wrong: wiring the agent to real telephony (Twilio, SIP trunks, or your existing PBX) with clean audio and correct routing • Inbound AI receptionists and outbound follow-up agents, with bookings, transcripts, and call summaries synced to your CRM (GoHighLevel, HubSpot, Zoho) via n8n, Make, or custom webhooks 🌍 REGIONAL TRUNK AND COMPLIANCE EXPERIENCE US and Canada (Twilio, Telnyx, VoIP.ms) · UK (Gamma, Gradwell) · Australia (Telstra SIP Connect) · UAE (TDRA-compliant Etisalat/du deployments) · South Africa (Vox, Switch Telecom, MTN) · Kenya and East Africa If your job involves phones talking to software, whether that's a CRM, an AI agent, a booking system, or a billing platform, there's a good chance I've already built it. Message me with what you're trying to automate and I'll tell you exactly how I'd approach it.

Signal Processing Engineer specializing in real-time audio DSP and embedded systems, with expertise spanning algorithm prototyping to production deployment. I develop high-performance audio solutions using C++ and JUCE for VST3/AU plugins, and leverage Python for DSP/ML research and rapid prototyping. My work encompasses the complete signal processing pipeline: • Algorithm Research & Prototyping: Using Python (NumPy, SciPy, Librosa, TensorFlow) for AEC, noise suppression, adaptive filtering, and machine learning integration • Production Implementation: Translating algorithms to optimized C++ for real-time performance in JUCE plugins and embedded systems • Embedded Deployment: Implementing DSP algorithms on Cortex-M4 with TensorFlow Lite Micro, focusing on memory and power optimization • Cloud Infrastructure: Building scalable backends and CI/CD pipelines on Azure, AWS, and Oracle Cloud for audio applications This full-stack expertise enables me to bridge signal processing research with production-ready implementations, from Python-based algorithm development to efficient C++ deployment.
