Project details
You have an idea for a tool that automates something people currently do by hand - research, lookups, analysis, data processing. The problem is building it properly means connecting multiple APIs, writing backend logic, adding an AI layer, and wrapping it all in an interface people can actually use. Most developers can handle one or two of those things. I handle all of it.
I've built tools like this. TrademarkLens queries 140+ official trademark registries, checks 12 social platforms, scans 30+ domain extensions, runs AI scoring on the results, and generates a PDF report - all from a single search. That's the level of tool I build.
You get a working product deployed live at the end. Not a script, not a prototype, not a demo. A real web tool your users or clients can open in a browser and use from day one.

AI Fitness Accountability App MVP (Framer + OpenAI)
Danielius has been an absolute rockstar to work with! He's a strong engineer, communicates well, and genuinely cares about building the right product rather than just ticking off tasks.
We're building an AI fitness coach, which has involved a lot of iteration, testing, and refining complex user flows. Throughout the project, he's been incredibly responsive to feedback, quick to fix issues, and willing to discuss ideas and challenge assumptions when it improves the product. The turnaround time has been consistently impressive.
What I've appreciated most is that he's approached the project like a true collaborator, not just a contractor. He's been proactive about suggesting practical solutions and improving the overall architecture rather than applying short-term patches.
I'd happily recommend Danielius to anyone looking for a talented, reliable developer who takes ownership of his work. I wouldn't hesitate to hire him again!

Build Gamified Guitar Learning Web App (Membership + Interactive Map)
Absolutely blown away by Danielius’ work. He’s a total wizard when it comes to web design and development. The final website exceeded my expectations in every way.
He went above and beyond throughout the entire project, communicated clearly, worked quickly, and constantly brought great ideas to the table that improved the site far beyond what I originally envisioned.
Couldn’t be happier with the result and I would work with him again in a heartbeat. Highly recommended.

Build an AI-Powered Wellness Platform (Agent-Based) + Marketplace (MVP)
Working with Danielius was one of the best decisions I made for my startup. He built a mobile wellness app from the ground up and delivered beyond every expectation — on time, on scope, and then some.
What sets him apart isn’t just technical skill, it’s his honesty and integrity. He told me what was realistic, flagged issues early, and designed the solutions in a way that was just very impressive . In a space full of freelancers who disappear after payment, he stayed engaged, communicated clearly, and treated my project like it was his own.
His innovation showed up in ways I didn’t ask for — he brought ideas to the table that made the product genuinely better. Efficient, sharp, and trustworthy from day one.
If my budget allowed, I would hire him full-time without hesitation. If you’re building something real and need a developer who will deliver what he promises and then go further — hire him. You won’t regret it.
