Benefits of working together
Over the years, I’ve built and maintained over 500 websites, delivering solutions that have reached more than 200 million people worldwide. With deep TypeScript expertise, I can quickly diagnose and resolve even the most complex issues—while offering proactive guidance to help prevent problems before they start.
Premium Quality, Independent Pricing
I work directly with the clients who hire me — no project managers or middle layers. When you need something, you can reach me by text, email, or phone. I also integrate seamlessly with your internal tools like Asana, Jira, or Slack to collaborate as part of your team.
Simple, Straightforward Communication
Clean, high-quality code matters — but so do communication, timelines, and collaboration. I keep you in the loop with regular updates, join team meetings, and work within your existing tools to stay aligned every step of the way.
Knowledge You Can Trust, Personality You’ll Enjoy
Over the past 12 years, I’ve built a reputation as a trusted custom TypeScript developer and analytics expert. My experience brings real value to the organizations I work with—but I always approach projects with an open mind and a no-ego attitude.
Minimal Plugins, Maximum Performance
Many TypeScript projects over-use the `any` type or create overly complex type hierarchies. I take a pragmatic approach — writing types that genuinely improve code safety and developer experience without adding unnecessary complexity. Clean, readable types are always better than clever ones.
I had the pleasure of working with Kegan, and it was a truly great collaboration from start to finish. He made the entire process feel smooth, collaborative, and well-organized from the beginning. Kegan was consistently helpful, quick to respond, and always willing to jump in with ideas and solutions to help bring our vision to life.
He did a fantastic job balancing design quality with practical execution, making sure everything looked great while still functioning well on the platform. His knowledge, professionalism, and positive attitude made him a pleasure to work with. I would highly recommend him to anyone looking for reliable, high-quality web design and development support.

Working with a freelancer for TypeScript development
Organizations are often hesitant to hire a freelancer over an agency—but with the right freelancer, the benefits can be significant.
CONCERN
SOLUTION
Reliability & Availability
Companies sometimes worry that freelancers won’t be as reliable as an in-house developer or agency, with concerns about slow replies or inconsistent availability.
I offer reliable, well-organized support for every client. My process ensures fast communication and dependable service—you can always reach me when needed. In all my years of freelancing, I’ve never abandoned a project or left a client hanging—something I’ve seen happen even with larger agencies when the right expertise wasn’t available.
Quality & Expertise
Larger organizations sometimes question if a freelancer can match the expertise of a specialized agency.
I have 10+ years of experience building business websites and leading complex projects for enterprise clients, with a strong focus on custom TypeScript development. Quality and expertise are central to everything I do, so you can feel confident you’re working with a skilled professional.
Scalability & Project Size
Mid-size and large companies may worry that a freelancer doesn’t have the resources to take on big or complex projects.
I’ve led large projects while working closely with in-house teams and outside partners. I specialize in scaling TypeScript codebases—from complex integrations to large databases—making sure everything runs smoothly and meets your goals.
Security & Compliance
For organizations handling sensitive data, security is a top priority. Some may question whether a freelancer can meet strict security and compliance standards.
Security is built into every project I take on. I follow industry best practices for data protection and compliance, including GDPR, to keep your systems safe. I’ve worked with clients in regulated industries and ensure all requirements are met.
Long-Term Support
Companies often worry that freelancers might not be available for long-term support, which could affect future updates and maintenance.
I offer reliable, ongoing support and maintenance and provide service-level agreements (SLAs) for long-term projects. My focus is on building sites that are easy to maintain and built for lasting success.
Process Integration
Companies may worry that a freelancer won’t easily fit into their in-house teams or existing workflows.
I’m experienced in working closely with in-house teams, adapting to your tools, workflows, and communication style. My goal is to collaborate smoothly and act as a true extension of your team.
Reliability
Organizations often prefer the structured accountability agencies offer and may worry a freelancer won’t bring the same level of professionalism.
I bring the professionalism and reliability you’d expect from an agency, paired with the personal attention of a freelancer. Clear timelines, detailed contracts, and regular updates ensure accountability every step of the way.
Risk of Becoming Dependent
Relying on a single person can feel risky if they suddenly become unavailable.
I reduce that risk by keeping thorough documentation, clear project plans, and writing clean, maintainable code that others can easily take over if needed. Transparency and communication are always a priority.
Limited Access to Tools & Resources
Larger organizations may be concerned that freelancers don’t have access to the same premium tools or enterprise-level resources as agencies.
Through agency and direct-hire work, I’ve used a wide range of advanced enterprise systems. I also rely on premium tools for development, SEO, analytics, and security—making sure your project has everything it needs to succeed.
Lack of Strategic Insight
Companies might think a freelancer doesn’t bring the same level of strategic focus or business insight as an agency.
With years of experience working with mid-size and enterprise clients, I understand how to align development with your strategic goals. I offer insights on SEO, conversion optimization, and key business metrics to ensure every decision supports your objectives.

Frequently asked questions for hiring a freelance TypeScript developer
People looking for a solid TypeScript developer tend to ask the same key questions—and for good reason.
What hourly rate do freelancers charge for TypeScript development?
Rates for TypeScript freelancers vary widely based on location, experience, reliability, and demand. If you’re working with someone who delivers top-tier results, expect their rate to be higher than what you’ll find in a quick Google or ChatGPT search.
Here’s a general breakdown of common pricing tiers:
HIGH: $100–$200/hr
This tier includes highly experienced developers—often with backgrounds in computer science or full-stack web application development. They deliver work that exceeds agency quality, and they’re the people you hire when your website is mission-critical and can’t afford downtime.
MID: $50–$100/hr
These developers are solid and reliable, and a great fit for most businesses. They may not specialize in advanced, application-like functionality but are more than capable for standard sites and light customization work.
LOW: $10–$50/hr
Budget-friendly freelancers who often rely on plugins to meet functional needs. This can work short-term, but in the long run, it may lead to performance issues or limitations—especially if the site needs to scale or be maintained over time.
How much does custom TypeScript development cost?
$500–$2,500 — Setup & Light Customization
This is usually a freelancer installing and lightly tweaking a pre-made theme. If you’re a small business with basic, informational needs, this may be just fine.
But expect minimal revisions—these projects are quick, and most of the flexibility comes from you doing DIY updates post-launch.
$2,500–$7,500 — Semi-Custom via Small Agency or Studio
You’ll likely work with a small team using the same process and tools they use for every site. It’ll look solid, but you might notice patterns across their portfolio.
Be careful—these setups can lock you into rigid tool stacks that limit flexibility later.
$7,500–$15,000 — Custom Design & Development
You’ll work with a freelancer or boutique agency who builds from scratch or near-scratch. Expect better quality and a more thoughtful approach.
That said, not all custom sites are built well. Look for someone who values clean, minimal code—that’ll save you headaches (and money) down the road.
$15,000–$50,000 — High-End Custom Solutions
At this level, you’re investing in tailored strategy, UX, and design. Projects often span several months and may include complex features or integrations.
This is also where well-organized freelancers or seasoned agencies shine. Just make sure you aren’t getting buried under layers of unnecessary tools.
$50,000–$250,000 — Big-Brand Agencies
This range covers enterprise-level work by top-tier design firms—the kind behind websites for recognizable brands and mid-to-large businesses.
If you need precision, polish, and full-service execution, this is where you go.
$250K+ — Elite Agencies for Global Brands
These are the firms that build sites for companies like Google or Fortune 100 brands. If that’s your world, you already know the level of quality (and budget) required.
Is TypeScript still a modern, relevant platform?
Absolutely—TypeScript remains a powerful and modern platform. It’s just as capable as any other system, but its true potential depends on the developer behind it.
One of TypeScript’s biggest strengths is its flexibility—but that can also be a downside. It gives developers a lot of freedom, which is great if you know how to use the right tools for the job.
Working with someone who understands the full landscape of modern web development makes all the difference.
How does TypeScript stack up against plain JavaScript?
Plain JavaScript still has its place, but TypeScript continues to lead with its type safety, tooling support, and growing adoption across the ecosystem with its flexibility, stability, and massive community. Its wide adoption means better support, constant improvements, and a huge ecosystem of tools—making it one of the most reliable and adaptable options available today.
Will TypeScript keep up with future trends?
TypeScript continues to evolve thanks to its massive community and Microsoft{RQ}s continuous investment of skilled developers. Its flexibility makes it well-equipped to adapt to future web trends.
The key is working with the right people who know how to make smart, forward-thinking decisions in a platform that offers so many possibilities. With the right guidance, TypeScript remains a powerful and future-ready choice.
Is TypeScript good for SEO?
TypeScript offers strong SEO capabilities right out of the box, and with the right developer it can be optimized to a very high level. Its flexibility also makes it great for publishing a wide variety of content, which is key for growing organic traffic.
While tools help, great SEO ultimately depends on the quality of your content. TypeScript makes it easier to manage and optimize that content, but success comes from what you publish, not just how it’s configured.
Can TypeScript easily scale?
TypeScript is highly scalable and can support everything from small websites to large, enterprise-level platforms—if built with the right planning and infrastructure. It can integrate with external systems and scale as your business grows, making it a flexible choice for evolving needs.
