AI transformation
- AI and automation strategy, then the implementation
- Process automation that reduces operating cost
- AI-readiness assessment of systems, data and team
- Transformation for traditional businesses
Hands-on technical partner
I build the systems, not the slide deck.
I'm Dejan Keri. For 14 years I have shipped production software, from large corporates through to two-person startups, plus two AI platforms of my own. I get companies AI-ready and accelerate what they are already building, hands-on, without a full-time hire.

Week 1Hands-on from the start
AI-first transformation
Cut operational cost through automation that actually ships, and position the business for what the next five years look like. Not a pilot that dies in a slide deck. Systems your team runs on Monday.
Growth acceleration
Get the architecture, the data and the team into a shape where AI compounds instead of stalling. Being AI-ready is engineering work, not a strategy document, and it is what makes the next stage of growth possible at all.
Real code, real impact
I write production code, review architectures and fix critical issues when your team needs it most. Not a deck about what someone else should build.
Expertise without the hire
Fourteen years of engineering experience on contract. Scale the engagement up for a launch, down for maintenance, and pay for what you actually use that month.

Who you're working with
I'm Dejan Keri, founder of T1C Technologies. Over 14 years I have worked across the whole range, from large corporate engineering teams through to two-person startups, and co-founded two AI platforms of my own. That range is the point: what breaks at scale and what breaks at ten paying customers are almost never the same problem, and the fix that works in one context will sink you in the other.
My job is turning technology into business results. While others deliver strategy documents, I deliver working systems. I still write code, review architectures and debug production issues, because the real work happens in the details, not in the summary.
My focus is AI transformation and automation, B2B SaaS, healthtech, fitness technology and energy systems. I am currently building an AI product of my own while advising clients, which keeps me honest about what these tools can and cannot do today.
How I work →Services
What I do
Three engagements, often overlapping. Most clients start with one and expand from there.
Growth acceleration
- Architecture for a fast launch or a stable scale-up
- Building and mentoring engineering teams
- Systems that hold when the load goes up tenfold
- Hands-on delivery, not a plan handed over
Advisory & due diligence
- Technical due diligence for investment decisions
- Deep-tech feasibility assessments
- Technical advisory for portfolio companies
- Technical risk evaluation and mitigation
Fit
Who I help
Companies that need to get AI-ready
The systems, data and team are not in a shape where automation can land yet. That is fixable, and it is the work that unlocks everything after it.
Seed and Series A B2B SaaS
The stage where the prototype that won your first customers starts buckling. Get the architecture right before it becomes the thing holding growth back.
Startups preparing for due diligence
Pass investor technical review with proper architecture, documentation and team structure, before the data room opens.
Companies between technical leaders
Bridge the gap when your technical lead leaves, so product development and team morale do not stall while you hire.
