01Who we are
Who we are
We're an independent studio. We started Kalebtec to ship the software our clients actually need — without rigid methodologies or contracts, without account managers, without the agency overhead.
Rowin writes the code. Mari runs the engagement. You talk to both of us, every week, on Slack and on the call — no handoffs, no surprises.
Senior engineers from day one. Decisions get made fast because there are no layers between you and the people doing the work. When you hire Kalebtec, you hire us.
Operating philosophy
We build software that grows with your product. The first launch is the start of the work, not the end. Pragmatic decisions, proactive communication, engineering that compounds — that's what makes a partnership worth keeping.

02Why Kalebtec
Why Kalebtec
A senior, AI-native engineering partner — not an agency, not a marketplace, not juniors learning on your budget.
Senior engineers, from day one
The people scoping your architecture are the people writing the code. No juniors learning on your budget, no handoffs.
Built to scale
We design systems for the load you'll have in a year, not just the demo next week — without over-engineering for problems you don't have yet.
AI where it earns its place
Production LLM features and automation wired into the workflows you actually run. Real capability, not hype.
Fast, focused cycles
Two founders, no layers, short feedback loops. Decisions get made and shipped in days — not lost to handoffs and process.
A partner for the long run
The first launch is the start of the work, not the end. We stay on to grow the product alongside you.
Transparent by default
Direct access to the people doing the work, proactive communication, and a reply within 24 hours.
03How we work
How we work
A clear path from first conversation to a product that scales — and a partner who stays.
- 01
Technical discovery
We map the problem, constraints, and goals before a line of code — so we build the right thing, not just a thing.
- 02
Architecture & product strategy
A pragmatic plan: the stack, the data model, the roadmap. Decisions you can defend a year from now.
- 03
Rapid development cycles
Short, shippable increments. You see working software every week — not status decks.
- 04
Continuous optimization
Performance, cost, reliability, and developer experience tightened as we go — not bolted on at the end.
- 05
Scaling & long-term support
We grow the system with your traffic and your team, and stay on as your engineering partner.
04What we ship
What we ship
Engineering built for scale — from architecture and AI to cloud, strategy, and the senior team to run it.
02 / Web
Web platforms
From marketing sites to data-heavy SaaS. We design and ship web platforms that scale with your traffic, your team, and your roadmap.
03 / AI
AI & automation
Practical LLM and automation pipelines wired into the workflows you actually run. Less hype, more shipping.
04 / Cloud
Cloud infrastructure
AWS, GCP, and Azure setups that scale when you scale and stay cheap when you don't. Observable, reliable, no surprises.
05 / Technical
Technical strategy
Pragmatic roadmaps grounded in your business, not in industry hype. Decisions you can defend a year later.
06 / Embedded
Embedded engineering
Senior engineers embedded with your team. We design, build, and grow alongside your roadmap — long-term, accountable, no handoffs.

07Questions, answered
Questions, answered
Straight answers to what founders ask us most before starting a project.
What kind of companies do you work with?
Mostly startups and growing companies that need senior engineering without building a full in-house team yet — from a first MVP to scaling an existing product.
Do you actually build with AI, or is it just a buzzword?
We ship production LLM features, automation pipelines, and AI-assisted workflows — but only where they measurably help. No AI for its own sake.
Who will I actually be working with?
The founders and senior engineers directly — Rowin on engineering, Mari on the engagement. No account managers, no handoffs to juniors.
Can you act as our fractional or outsourced CTO?
Yes. We provide technical leadership, architecture, and hiring guidance for startups that need a senior technical partner without a full-time CTO on payroll.
How fast can you start, and how do you communicate?
Usually within a couple of weeks. You get direct Slack access, weekly calls, and a reply within 24 hours.
What does an engagement cost?
It depends on scope. We run a fixed-price discovery first, then propose a clear plan and budget — no surprise invoices. Book a strategy call and we'll give you a straight answer.
