Hello, I'm ...

Muhammad Waqar

Senior Software Engineer | Building Scalable Solutions for Fintech, Healthcare & Web3

7+ years experience 500k+ users impacted Blockchain & Cloud Expert

I am a Senior Software Engineer with 7+ years of experience designing and scaling web, mobile, and blockchain applications across fintech, healthcare, and real estate.

I specialize in building secure, high-performance platforms that support large-scale user bases and deliver measurable business impact.

My expertise spans modern JavaScript frameworks (React, Next.js, Node.js, Nest.js) and blockchain technologies (Ethereum, BSC, Bitcoin Ordinals, Smart Contracts, Web3), complemented by strong experience in microservices and AWS serverless architectures.

Throughout my career, I've led cross-functional teams, optimized legacy systems to improve stability and efficiency, and delivered innovative solutions that drive growth and adoption. I've built platforms serving 500k+ active users, architected Bitcoin Ordinals minting infrastructure for Web3 gaming, developed telehealth solutions for the UK's NHS, and engineered real-time collaboration tools with advanced database features.

Currently, I'm working as a Senior Software Engineer at tappengine, while also contributing to cutting-edge projects that leverage AI, blockchain, and serverless technologies. Previously, I led the development of OLAB at Yadn (a visual canvas and database platform), built Web3 gaming infrastructure at Zogi Labs, and architected serverless solutions at Pixelpk Technologies.

I'm passionate about solving complex technical challenges with clean, scalable architecture—always with a focus on user experience, security, and performance. If you're looking for a dedicated professional to help bring your vision to life, feel free to reach out.
