Welcome to Armed Code, LLC — where precision meets performance in both firearms compliance and cutting-edge software development.
Founded with the vision to bridge the gap between the world of digital innovation and firearms industry compliance, Armed Code, LLC is proudly owned and operated by a federally licensed firearms professional and experienced full-stack software developer.

My name is Kevin Fonseca — and I wear two hats with confidence and integrity: one as a Federal Firearms Licensee (FFL 01) and Special Occupational Taxpayer (SOT 03), and the other as a seasoned JavaScript software engineer with years of hands-on experience building scalable, efficient, and maintainable digital solutions.

This dual expertise allows Armed Code, LLC to operate at a unique intersection of industries, offering services that are both regulatory-compliant and technologically sophisticated. Whether you're a gun enthusiast looking to process a legal transfer, or a business needing tailored software development, you're in the right place.

Firearms Transfers & Compliance Services

As an FFL 01 holder, I am federally licensed to handle firearms transfers, enabling lawful and secure transactions for both private individuals and businesses. I also hold an SOT 03, which further permits me to conduct transfers of NFA-regulated items such as suppressors (silencers), short-barreled rifles (SBRs), and other Title II firearms under the National Firearms Act.

Here’s what that means for you as a customer:

✔️ Firearms Transfers (FFL 01)

Whether you’re purchasing a firearm online or from another out-of-state seller, the transfer must be handled by a licensed FFL in your local area. I provide fast, compliant, and affordable firearms transfer services, ensuring that all BATFE (Bureau of Alcohol, Tobacco, Firearms and Explosives) regulations are followed to the letter.

Each transfer includes:

Completion and review of Form 4473 (Firearms Transaction Record)
Background check via NICS, unless exempt
Secure and discrete handling of your firearm(s)
Storage in a monitored environment (when needed)
Transparent pricing with no hidden fees ($10 NON-NFA firearms and $45 NFA items)

Transfers are available by appointment only to ensure you get one-on-one attention in a secure, professional setting. Weekend and evening hours are often available to fit your schedule.

✔️ NFA Transfers (SOT 03)

As a Class 3 Special Occupational Taxpayer, I am authorized to receive and transfer NFA items such as:

Suppressors / Silencers
Short-Barreled Rifles (SBRs)
Short-Barreled Shotguns (SBSs)
Any Other Weapons (AOWs)
Machine Guns (transferrable pre-1986 only)

These types of transfers involve additional paperwork and background checks, typically involving ATF Form 4 for individual or trust applicants.

All NFA items are held securely until your tax stamp is approved. I’ll notify you the moment it's ready for pickup.

While I do highly encourage you to choose me as your FFL, please make sure to avoid shipping Machine guns to my home address as I do not have the storage needed for them; everything else such as Silences, SBRs SBSs and AOWs are just fine.

Software Development Services

In parallel with my firearms services, I also run a startup software development consultancy focused on building full-stack applications using today’s most reliable and high-performing technologies.

My core development stack includes:

Node.js – for building scalable backend services and APIs
Express.js – minimal and fast web framework for Node.js
MongoDB – a flexible NoSQL database ideal for performance and rapid development
React.js and Next.js – for building dynamic, modern user interfaces and server-side rendered applications

This isn’t just a hobby or side hustle. I’ve worked on personal projects and helped github applications ranging from small startups to enterprise-grade platforms, always delivering clean, secure, and optimized code.

If you're a business owner, entrepreneur, or independent creator looking to bring a digital product to life — whether it’s a dashboard, a custom CRM, a storefront, or even a SaaS app — I can take it from idea to launch with full-stack expertise.

✅ What I Can Build for You:

RESTful APIs
Authentication & authorization (JWT)
Admin dashboards and internal tools
E-commerce solutions (custom carts, Stripe integration, inventory management)
MongoDB performance optimization and indexing
SEO-friendly static or dynamic sites with Next.js
Server-side rendered applications for blazing-fast load times

I also offer code audits, refactors, and one-off consultations if you already have a dev team but need expert guidance.

Why Combine Firearms & Code?

At first glance, it may seem like these are two entirely different worlds. But in reality, there is significant overlap between technical precision and legal compliance. Both domains demand:

Thorough documentation
Meticulous record keeping
Deep understanding of regulations (BATFE for firearms, GDPR/PCI for software)
A mindset of responsibility and forward thinking

Being an FFL and a full-stack developer also allows me to build digital solutions for the firearms community — an area often underserved by generic developers who don’t understand the nuances of 2A compliance and ATF workflows.

My long-term vision includes creating SaaS tools for FFLs, online stores for custom gun shops, and inventory management platforms tailored for firearms dealers. If you're in the industry and tired of using outdated, bloated systems — let’s build something better.

Future Services & Expansion Plans

As Armed Code, LLC continues to grow, I plan to expand my offerings in both verticals:

🔧 Firearms Engraving (Coming Soon)

In the near future, I will be offering custom weapons engraving services using fiber laser engraving technology. Whether you need an NFA-required serial number engraving or a fully custom design for your AR-15 lower, this will be a service that prioritizes precision, durability, and aesthetics.

Stay tuned for updates — as I’ll soon be accepting reservations and inquiries for this service. It will be especially useful for those applying for Form 1 approvals and needing compliant markings done locally.

🛍️ Online Store for Gun Accessories & More (In Development)

I’m also planning to launch an online store that will feature:

Gun accessories (handguards, charging handles, safety selectors, triggers)
Apparel
Range gear and everyday carry (EDC) items
Branded merchandise for Armed Code, LLC
Developer-centric merchandise for those who, like me, live in both worlds

The store will reflect my taste for quality, functionality, and unique style — curating items that aren’t mass-produced junk but well-reviewed, well-designed, and worth owning.

All accessories will comply with state and federal laws, and special attention will be given to inventory that’s NFA-friendly or helpful for those building SBRs, AR pistols, or suppressor hosts.

My Values

At Armed Code, LLC, everything I do is guided by a commitment to ethics, legality, and customer service. Whether I’m processing a transfer, building an app, or helping someone start their first NFA application, I aim to treat each project with care and precision.

I believe in:

Transparency – no hidden fees, no BS
Responsiveness – quick turnarounds, clear communication
Quality – in both code and craftsmanship
Integrity – following the law, every time
Innovation – especially where firearms and tech intersect

I’m not here to scale to the moon or run some massive corporate entity. I’m here to build a reliable, boutique-style business that serves both the local community and niche markets with professionalism, attention to detail, and a personal touch.

I am currently based in Fort Worth, Texas, and I operate by appointment only for all firearm transfers to ensure privacy and efficiency.
