Senior TypeScript / Next.js Engineer for Payments Integration & Go-Live (Existing Codebase)
Excellent developer. I engaged Waseem for the launch-critical payment, payout and identity integrations on my web platform and he delivered to a high standard throughout. Strong technical quality on a modern stack (TypeScript, Next.js, Prisma, Postgres), genuine attention to security, and real ownership of the work. Communication was clear, turnaround fast, and when I sent work back for a change he grasped the reason at once and fixed it properly. Reliable, fast, and careful with the parts that matter. Would gladly work with him again.

QQQ Real-Time Trading Scanner Trial Build
This was my first time hiring on Upwork and I got lucky finding Waseem. I gave him a rough idea and he turned it into a real product, a Python system that watches real time data and sends alerts straight to my phone on Telegram with the exact numbers I need. Then he got the same thing running inside the platform I use every day, live the same week I asked. True full stack developer, servers, database, API connections, all handled on his own.
When I thought something was broken he didn't guess, he pulled the logs, showed me what happened and fixed it. He even cut my monthly hosting costs without me asking. The system has been running since launch and I have not had to touch it once. Thinks like an AI engineer, automates everything. First hire on here and he set the bar high, I already have more work lined up for him. Take him if he has an opening.

Solo Select — Security & Tenant-Isolation Review
Waseems communication was excellent and he delivered quickly. We are using him and his team now for another big project. He has been wonderful to deal with and has picked up on very complicated logic on a niche program very quickly.

Full Stack Web Application Development
Waseem delivered cloud infrastructure work for our HealthTech platform that was clean, secure, and production-ready. He moved fast, communicated proactively, and stayed engaged well past the initial scope to support post-deployment refinements and edge-case fixes. Strong across AWS, Docker, Node, and Postgres and easy to work with when requirements shifted mid-build. Would hire again without hesitation. Highly recommended for any team that needs a serious full-stack engineer with healthcare-grade attention to detail.

WHAT MAKES ME DIFFERENT
Most developers build exactly what you spec. You get someone who tells you what the business actually needs first, before you spend the budget, then builds it to last. Five plus years leading architecture, making build-versus-buy calls, and operating as fractional CTO for founders without a full-time technical hire. The rare part: shipped HIPAA-compliant healthcare systems and SEC-compliant fintech infrastructure to US standards, where audit trails and reliability are non-negotiable. Few AI developers can claim that honestly.
PROVEN IN PRODUCTION
The VP of Enterprise Solutions at Fukuda Denshi USA endorsed an HL7 gateway I built for their HealthMosaic platform, now moving 10,000+ clinical messages a day from 200+ hospital monitors at a 99% delivery rate, saving an estimated $400K a year. For a US fintech startup, a SEC Reg CF compliant backend with 248 passing tests and zero production bugs.
What clients say:
"He thinks like a product owner, not just a developer, and delivered production-ready work ahead of schedule." Justin R., VP of Enterprise Solutions, Fukuda Denshi USA
"By far the best developer I've worked with. If you need someone who delivers, hire him." Carmen M., Business Consultant
"Clean, well thought out design, finished weeks ahead of schedule." Jett S., Founder, NxtSzn
