(You can check the demo site at http://188.166.146.151/v3/web/ username:admin password:123456) Am committed to the projects I work on and need to see them through to completion. I understand that solving the user's problem is the end goal. I stay up to date with the latest trends and are excited to learn new languages, tools, and best practices. I thrive in teams and projects that span timezones and cultures. I hold a Bsc in Software engineering having attained a 2-1 thus am very conversant with the best software practices and standards from the complete Software Development Life Cycle to the final hand over to clients. I Have developed both back-end (extensive) and frontend systems using HTML, HTML5, JS, PhP (both procedural and OOP) ,Java and MVC frameworks (Yii, Yii2, CodeIgniter & Laravel) and database like Mysql, Sqlite, MSSQL, Redis running on servers like Apache for over 10 years.

I also make sure the system has descriptive audit trail to enable the system owner keep track of what is happening behind the scenes. I have developed systems both Windows and Linux platforms for several years and thus can administrate any system in those platforms. I develop solutions that have a futuristic approach with an aim in incorporating elements of Artificial Intelligence, Machine Learning and Data Analytic. When am not programming, I usually take out my violin and start making some music covers of popular songs though I have been a beginner for a while now. I also like jogging especially in the mornings and I have been beating my record (by a few seconds though) every new run. Am a fun person and usually excited from learning new technology every day.

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.

Every email that lands in spam instead of the inbox is a password reset that fails, a payment notice no one sees, a user who quietly churns. I find out exactly how much that's costing you, then fix the infrastructure so it stops. I'm an email deliverability and infrastructure consultant with 13+ years across high-volume sending, multi-tenant platforms, and ESP architecture. I work with companies sending real volume: transactional, lifecycle, billing, notifications. A missed inbox here isn't a marketing metric. It's a support ticket, a churned user, or a failed payment. How I work: I start with a paid deliverability audit, not a guess. You get a written report showing exactly where your mail is landing, why, and what it's costing you, before you commit to anything bigger. Most consultants start with a fix. I start with the number. What I actually do: Authentication setup and repair (SPF, DKIM, DMARC, BIMI), so Gmail and Yahoo stop filtering you by default before your content is ever read IP and domain reputation management: warming, pool architecture, blacklist recovery. This is the difference between one bad sender poisoning your whole domain and one you can isolate and fix MTA-level infrastructure (KumoMTA, Postfix, Momentum, queue and throttling policy), or direct work inside Mailchimp, Klaviyo, ActiveCampaign, and SendGrid when the problem is authentication or list health rather than infrastructure Drift monitoring. Deliverability degrades over time even on systems that were configured correctly once, often with no error to flag it. I catch it before it costs you Multi-tenant and per-tenant DKIM setups for platforms sending on behalf of others, so one bad client doesn't tank deliverability for everyone else on the platform Ongoing strategic monitoring, not a one-time fix, because reputation is a moving target, not a setting you configure once Background that's relevant to you: I've built and operated sending infrastructure across dating platforms, real estate ESPs, and multi-tenant SaaS, including a 49+ egress IP operation across multiple domains and provider pools. I've debugged the failure modes that tank deliverability without ever throwing an error: snowshoe patterns, reputation contamination across shared IPs, and DMARC policies that look correct but fail silently. I'm not selling you a service you can't measure. Every engagement starts with a clear number (what it's costing you now) and ends with a clear number (what changed). If you want a long-term relationship, I also offer ongoing monitoring so the fix doesn't drift back to where it started six months from now. If your emails aren't reaching the inbox, let's find out exactly why, and exactly what it's costing you.
