I'm Marian Panzer. I build custom tools and systems that bridge the cracks between your platforms, automate what slows you down, and turn fragmented workflows into something that actually works.
Off-the-shelf tools solve 80% of the problem. The remaining 20% is the hard part: the weird edge cases, the gaps between systems, the workflows no SaaS was built for. That's where everything breaks down.
Opsifly is my answer to that 20%. I analyse your processes end-to-end, identify where data gets lost, where manual work piles up, where systems don't talk to each other. Then I build the tools that fix it. Custom. Tailored. Built to fit your reality, not some vendor's roadmap.
Whether it's content operations, logistics, booking systems, production management or anything in between. If there's a process that can be smarter, I'll make it smarter.
I sit in the middle of your toolchain and build the connective tissue that's missing. So data flows, processes connect, and nothing falls through the cracks.
Every project is different. But the pattern is the same: find the inefficiency, understand the real workflow, build the exact tool that fixes it.
Your CRM doesn't talk to your project tool. Your booking system lives in a spreadsheet. I build the bridges: APIs, sync layers, middleware. The kind that make your tools work as one.
When no existing software fits your use case, I build it from scratch. Calculators, dashboards, booking engines, management platforms. Tailored to your exact workflow.
Rapid prototyping to production. AI-augmented development that gets working tools into your hands in days, not months. Fast iteration, real results.
Repetitive tasks, manual handoffs, copy-paste workflows. I identify them, map them, and automate them. Less busywork, more output.
Not AI for hype. AI where it creates real leverage: in briefing, generation, analysis, classification. Built into your actual workflow, not bolted on.
Sometimes the problem isn't a missing tool. It's the whole process. I map your operations end-to-end, redesign the flow, and build the infrastructure that makes it work holistically. From scattered chaos to a system that compounds.
Real projects, real users, real problems solved. Here's a selection of custom systems I've designed and engineered from scratch.
Full-stack booking & management platform for a Pilates, Barre and Mental Health studio in Meerbusch. Built from zero: class scheduling, membership management, payment processing (PayPal, Stripe, Apple Pay), SMS verification, real-time availability, WhatsApp integration, admin dashboard. Everything the studio needs to operate, in one custom system.
Visit miucoco.deA passion-driven side project built to help Deutsche Bahn rail workers, especially DB InfraGO field staff, to navigate structural infrastructure faster. Interactive map tool for locating bridges, tunnels, level crossings and stations along rail lines, with route search, kilometer filtering and real-time map visualization. No client brief. Just a gap I saw and decided to close.
Visit kib.opsifly.deReal-time coordination app for one of the Rhineland's largest traditional parades. Live marching-order tracking, intersection signal control, and corps navigation — built so that thousands of participants and organisers stay in sync during the procession. A PWA that works reliably outdoors, on any device, in real time.
Integrated management platform for the entertainment and event production industry. Covers the full pipeline: offer & quotation management, project planning, inventory & warehousing, and 3D stage planning — all in one system. Built to replace scattered spreadsheets and disconnected tools with a single, purpose-built operations hub.
Digital economic development platform for a municipality in North Rhine-Westphalia. Interactive map-based location explorer with filterable commercial properties, auto-generated PDF exposés, a funding navigator that matches businesses to relevant grant programs, and a structured settlement inquiry system with guaranteed 48h response times. Replaces fragmented municipal processes with one cohesive digital experience.
No bloated timelines. No feature creep. I understand your problem, build the right thing, and ship it fast.
I map your current operations, talk to the people who use them, and identify exactly where time, data and money get lost. No assumptions, just reality.
I architect the solution and start building immediately. Working prototypes within days, not decks. You see progress from week one.
The tool goes live, your team uses it, and we iterate based on reality. Built to evolve, not to be a one-off project that collects dust.
Tell me what's not working. I'll tell you how I'd fix it. No pitch decks, no sales calls. Just a real conversation about your operations.
