About Me
I'm a Senior Software Engineer with 9+ years of hands-on experience building web applications that actually work. I specialize in WordPress, React, and Next.js—but what matters most is solving real problems for businesses. Whether it's setting up custom solutions, optimizing site speed, or building scalable platforms, I focus on delivering results that drive business growth.
Over the years, I've worked with businesses across North America and Europe, helping them streamline their operations and improve their online presence. I'm passionate about clean code, smart architecture, and creating solutions that last. I love collaborating with teams, learning new technologies, and taking on challenges that push me to grow as an engineer.
I also handle SEO end to end, from technical audits and Core Web Vitals to keyword research, search intent, metadata, internal linking, image SEO, redirects, sitemaps, robots.txt, and schema markup. I have audited 10+ websites with measurable ranking improvements and steady organic traffic growth, using tools including Semrush, Screaming Frog, Google Search Console, GA4, and Google Tag Manager.
In AI automation, I build workflows that save teams time by connecting AI tools with the systems they already use. This includes an automated newsroom pipeline that monitors news, rewrites it with AI, and publishes drafts into WordPress, plus integrations for DoNexus that connect phone, WhatsApp, email, and CRM systems.
I graduated with a degree in Computer Science from the University of Gujrat in 2016. When I'm not building websites or applications, I'm exploring new tech, contributing to open source, or experimenting with emerging frameworks and tools.

Case Studies
Deep dives into complex problems and how I solved them
Unified Communications Integration
Multi-channel System Architecture
The Challenge
A customer-facing business had communications scattered across four separate systems: 3CX phone system, WhatsApp via Twilio, Outlook email, and an external CRM API. Agents were constantly switching between tools, copy-pasting information, and losing context when customers reached out through different channels.
The Solution
I built a unified platform that consolidated all communication channels into one coherent system where agents could see full customer context regardless of how they were reached.
- →3CX Integration: Polled ActiveCalls every 2.5s, captured recordings, and passed them through Whisper + GPT-4o for automatic transcription and summarization
- →Twilio Layer: Webhook-driven WhatsApp messaging, creating conversation threads tied to customer profiles in real-time
- →Email Integration: Microsoft Graph API for reading and sending emails directly from the unified interface with full threading preserved
- →CRM Sync: Every interaction written back to customer records in real-time, ensuring any agent had instant context
Results
- •Average handle time reduced by ~30% — agents no longer hunting for context
- •4 tools replaced by 1 unified view — eliminated context-switching
- •First response time dropped significantly across all channels
- •CSAT scores improved as customers stopped repeating themselves
Key Learnings
The hardest part wasn't connecting APIs. It was designing the data model so that four different communication objects — a call, a message, an email, a CRM note — could all be stored, retrieved, and displayed in a way that felt coherent rather than stitched together. That's the real work in integration projects.
