I ship AI products
End to end.
I am Kostandin Gjini. For five years I have built apps, SaaS, AI tools, and the businesses around them, mostly from zero. This is the work, live and clickable.
◆Tirana, Albania. Open to work across Europe and fully remote.
A builder who ships.
I ship working AI products end to end, fast, without waiting for a team. I take a real business problem, wire up the LLM, the data, the automations, and the interface, and put something usable in front of users.
I have done this for nearly five years as a founder under real revenue pressure, not as a side project. I build retrieval-augmented systems, agents, and automation pipelines that run in production, and I sit next to the customer while I do it.
Five years of building
Hover any role to dig in. Real ventures, real revenue, real users.

From a real problem to a shipped system
Forward-deployed by default. I sit next to the customer, build it, and iterate live, then make it dependable.
Ship the first version
Scope the real problem with your team, wire up the LLM, data, and interface, and deploy a working AI feature or automation in weeks, not quarters.
Make it reliable
Add evaluations and monitoring, automate the manual workflows around it, and hand your team dependable tooling they can trust day to day.
Grow the impact
Expand to new use cases and integrations, track measurable results, and document so the system keeps running without me as a bottleneck.

Real campaigns, real numbers
A few documented results from the lead-gen work. No rounding up.
190K emails at a 1.9% reply rate turned a cold list into 230+ opportunities and 38 booked meetings for an online merchant.
A focused, low-saturation roofing campaign hit a 46% positive reply rate and 110 opportunities. Niche beats broad.
Re-engaged 484 cold leads to a 22% reply rate and a 54% positive rate, roughly 10x a typical cold benchmark.

I built a brain that
writes in any voice.
A retrieval-augmented platform I built from the ground up. It ingests thousands of hours of long-form creators, analyzes how each one actually talks, and lets an AI write, advise, or roleplay in their voice, grounded in real transcripts and cited line by line.
> write a hook like Hormozi
"Most people don't have a money problem. They have a decision problem wearing a money costume."
✓ grounded in 632 source transcripts
