Loading amazing portfolio...
I turn coffee into scalable APIs and boring manual tasks into smart automation.
Most backend developers write code that barely survives production. I write code that thrives under pressure.
Over ten years building systems for companies that can't afford downtime. Financial platforms processing secure transactions. Healthcare systems managing patient data. E-commerce backends handling high-traffic spikes.
The kind of work where "it mostly works" isn't good enough. Where every query matters, every second counts, and every edge case will eventually happen.
Design schemas that scale. Write queries that stay fast at 10M+ records. Set up replication, partitioning, and caching strategies that actually work in production.
Build REST and GraphQL APIs that handle real load. Integrate with payment processors, third-party services, and legacy systems without breaking things.
Eliminate manual work that shouldn't exist. Build automated workflows, data pipelines, and background job systems that save hours daily.
Before writing a single line of code, I understand your business logic, data flows, and growth projections. Map out the architecture that will support your goals 12 months from now.
Write comprehensive tests first. Build in small, testable increments. Deploy to staging environments that mirror production. Performance test with realistic data volumes.
Set up CI/CD pipelines, monitoring, alerting, and logging. Document everything. Train your team. Be available for the critical first weeks after launch.

Every successful business runs on systems. But most systems are held together with duct tape, manual processes, and the prayers of overworked employees.
I don't just build software. I engineer competitive advantages.
The Foundation That Never Cracks
They build for today's traffic, not tomorrow's success. Their APIs break under load. Their databases become bottlenecks. Their code becomes unmaintainable technical debt.
I architect for scale from day one. Clean, documented code that your future developers will thank you for. APIs that handle 10x growth. Database designs that stay fast at millions of records.
"Marjon rebuilt our core API from scratch. We went from constant crashes to handling 50x our previous traffic without a single issue. Best investment we ever made."
Your 24/7 Digital Workforce
Your employees spend hours daily on repetitive tasks. Data entry, report generation, file processing. That's significant productivity loss that automation can eliminate.
If a human does it more than 3 times, a machine should do it forever. I build intelligent workflows that handle exceptions, adapt to changes, and scale infinitely.
Automated daily reconciliation of 10,000+ transactions across 5 bank accounts.
Intelligent email parsing and ticket routing with 95% accuracy.
Real-time sync between warehouse, e-commerce, and accounting systems.
Turn Information Into Profit
Your data is scattered across 15 different tools. Reports take days to generate. Decisions are made on gut feeling instead of facts. Competitors are eating your lunch.
I create single sources of truth. Real-time dashboards that update as your business moves. Predictive analytics that spot opportunities before your competition does.
Make Everything Talk
Your CRM doesn't talk to your accounting software. Your e-commerce platform lives in isolation. Data gets manually copied between systems. Errors multiply. Efficiency dies.
I create seamless connections between any systems. Real-time data sync. Automated workflows that span platforms. Your business runs like a single, intelligent organism.
"We had 8 different systems that couldn't talk to each other. Marjon built a central nervous system that connected everything. Now when a customer places an order, inventory updates, accounting records it, and shipping labels print automatically."
The Brain of Your Business
Slow queries bring your app to its knees. Poor design creates data corruption. No backup strategy means one crash destroys your business. Scaling becomes impossible.
I design for tomorrow's data volume today. Optimized queries that stay fast at scale. Bulletproof backup strategies. Database architectures that grow with your business.
Advanced indexing strategies and query rewriting for sub-millisecond responses.
Encryption at rest and in transit, role-based access, audit trails.
Horizontal partitioning, read replicas, caching layers for infinite scale.
Strategy That Scales
Your team is stuck in analysis paralysis. Technology choices are made by gut feeling. Architecture decisions bite you later. No one sees the big picture.
I see three moves ahead. Technology choices aligned with business goals. Architecture that supports your 3-year vision. Teams that ship faster with fewer bugs.
Deep technical reviews that identify bottlenecks before they break your business.
Transform junior developers into senior contributors through proven methodologies.
Technology roadmaps aligned with business objectives and market opportunities.
"Marjon didn't just write code - he transformed how our entire engineering team thinks. Our deployment frequency went from monthly to daily. Bug reports dropped by 85%. Most importantly, our developers are actually excited about work again."
These aren't costs - they're investments in your competitive advantage
Every day you wait is money lost to inefficiency, opportunities missed to competitors, and sanity sacrificed to broken processes.
Real projects, real results. Here are some of the amazing systems I've built for incredible clients around the world.
A complete music streaming platform with user authentication, playlists, and social features. Handles 10K+ concurrent users!
Advanced analytics platform processing millions of audio files daily with real-time insights and automated reporting.
Complete logistics management system with route optimization, tracking, and automated invoicing. Saving clients 30% in costs!
Mission-critical banking software handling secure transactions daily with security-first architecture and zero downtime.
Complete automation platform that reduced manual work by 80% with invoice processing, data entry, and report generation.
I've worked on many more exciting projects. Want to see them all?
Let's discuss your projectThese aren't cherry-picked reviews. They're honest feedback from companies who trusted me with systems that actually matter to their business.
Microsoft Azure Project
LAMP REST API Development
"Marjon did a great job on a LAMP REST API deployment to Microsoft Azure. We'd be happy to work with this freelancer again."
Treatment Pages Project
"Great technical skills, great communication skills as well. Marjon is very easy to work with, he is very structured and organized which makes for a great project experience."
30 Minute Consultation
"Great consultation experience. Provided detailed feedback and action steps."
Long-term WordPress Project
"Marjon was great to work with, very responsive, good communication and quality work. Thanks Marjon."
Senior Backend Engineer, Series A Startup
"I've been coding for 12 years. Marjon's code is the cleanest I've ever seen. Zero technical debt, comprehensive tests, and documentation that actually makes sense. Six months later, our team still hasn't found a single bug in his implementation."
Not every project is a massive success story. I've had difficult clients, changing requirements, and technical challenges that took longer than expected. But I've never delivered broken code, missed a final deadline, or left a client without proper documentation and support.
You know that feeling when your database crashes at 2 AM? When your "simple" integration takes 3 months and still doesn't work? When you're spending more time fixing bugs than building features?
I build systems that don't break. Ever.
Tell me about your project and I'll show you exactly how we can solve it. No sales pitch, no generic proposals. Just a real plan for your specific situation.
