What changes when you hire me

→

Your idea becomes a real product

Not a mockup. Not a prototype. A fully working application your customers can pay for — deployed, tested, and ready to scale.

→

Your manual work disappears

AI agents handle what used to take your team hours. Workflows run automatically. You focus on strategy, not repetitive tasks.

→

Your tech debt stays at zero

Clean code. Proper documentation. CI/CD pipelines. Your next developer (or your team) can pick up right where I left off.

FAQ

Common Questions

How do you handle projects in different time zones?

I use async-first communication with detailed daily updates via Slack or your preferred tool. I maintain 4–6 hours of overlap with US/EU time zones and respond within 24 hours. Loom recordings, documented PRs, and shared project boards keep everyone aligned regardless of location.

What’s your typical project timeline?

MVPs typically take 3–6 weeks. Larger, complex platforms are scoped individually once the requirements are clear — quoting a number before that is guesswork. Every project starts with a discovery call and a scoping document, so we agree on milestones, deliverables, and deadlines before any code is written.

Do you provide post-launch support?

Yes — post-launch support is available, with the scope agreed as part of the engagement rather than fixed in advance. For ongoing work I offer maintenance retainers covering monitoring, dependency and security patching, and monthly improvements. Retainers are scoped on a call, and I reply to every message within 24 hours.

What technologies do you specialize in?

I specialize in React, Next.js, Angular, Node.js, NestJS, Express, TypeScript, Python, and Django on the application side. For databases I work with PostgreSQL, MongoDB, Firebase, and Supabase. On the AI side I build with OpenAI, Claude AI, LangChain, and n8n for workflow automation. Infrastructure includes Docker, AWS, Azure, and Vercel.

How do you ensure code quality?

I follow a strict quality process: TypeScript for type safety, automated testing with Jest and Cypress, CI/CD pipelines for every deployment, thorough code reviews, and comprehensive documentation. Every project ships with clean, maintainable code that your team can easily extend.

Can you work with my existing team?

Absolutely. I integrate seamlessly into existing teams using your Git workflow, code standards, and communication tools. I’ve collaborated with cross-functional teams of designers, PMs, and backend engineers on platforms like GitHub, GitLab, Jira, and Linear.

What’s your pricing structure?

Most engagements start around $5K; smaller well-scoped work is considered case-by-case. Fixed-price works best for well-defined scopes, while hourly suits ongoing development or evolving requirements. Every engagement starts with a free discovery call and a detailed proposal so there are no surprises.

How do I get started?

Book a free discovery call or send me a message at contact@waseemahmad.dev. We’ll discuss your goals, timeline, and budget, and I’ll follow up with a tailored proposal within 24 hours. No commitment required — just a conversation to see if we’re a good fit.
