Hassan Ul Hasan Khan

I am a Senior Project Manager and Solutions Architect with 10+ years delivering enterprise VoIP, UCaaS, CCaaS, and AI communications platforms across Australia and Pakistan. At SOLANT Pty Ltd (Australia), I architect and deliver production AI systems alongside managing 13+ concurrent projects. My current flagship is a confidential multi-tenant AI phone receptionist SaaS — designed from scratch including system architecture, UI/UX across three portal tiers (SuperAdmin, Channel Partner, End User), and full-stack development using Asterisk 23.4.1/PJSIP, PostgreSQL real-time SIP config, ElevenLabs Conversational AI, Fish Audio TTS, React, Node.js, and REST APIs. The platform includes enterprise-grade features: TOTP 2FA, session revocation, audit logging, scoped API tokens, CDR analytics pipeline, collision-safe DID provisioning, and soft-delete data architecture. I also delivered an AI voice agent processing 500,000+ calls/month at AUD $40K annual infrastructure cost — with 55% of Level 1 calls resolved autonomously across five commercial verticals. Other projects include VoicePilot (25,000+ DIDs, $12K MRR), Tone2Pay (PCI-DSS, saving $40K/yr, full ROI in 15 months), MS Teams Direct Routing, enterprise SIP softphone, and RAG chatbots. At Wateen Telecom, I led a zero-downtime migration of 30,000+ customers in 48 hours within USD $110K budget — banks, hospitals, and national carriers — avoiding $20K in SLA penalties. I also managed AdvOSS Class 5 Softswitch (35,000+ customers, 200,000+ DIDs), ACME SBC LDI expansion (10,000 concurrent sessions), Ribbon SONUS OS upgrade (10,000+ nodes), and VMware vCenter 6.7 consolidation (24 hosts, 155 VMs, dual DC) — solo. I am certified in HCIE Routing & Switching, CCNP, CCNA, RHCSA, ITIL, and SSCA SIP. Completing PMI-CPMAI (AI Project Management) in December 2026. Open to remote Senior PM, Solutions Architect, CCaaS, UCaaS, and AI voice platform roles globally. Available for immediate remote engagement across APAC and EMEA timezones.
