Why Tessera

Most software fails quietly: missed deadlines, bloated scope, code nobody wants to touch. We run small senior teams, ship in two-week increments, and hold the line on quality until your product is live.

What we do

Four disciplines,
one accountable team.

  • 01

    Product Engineering

    Web applications, SaaS platforms, and internal tools — architected properly, tested, and built to be maintained by whoever comes after us.

    • Web Apps
    • SaaS
    • APIs
    • E-commerce
  • 02

    Cloud & Infrastructure

    Deployment pipelines, container orchestration, and observability. Your product stays fast and stays up, without a full-time ops team.

    • AWS & Cloudflare
    • Kubernetes
    • CI/CD
    • Monitoring
  • 03

    AI Systems

    LLM-powered features that survive contact with real users: retrieval pipelines, agents, evaluation harnesses, and cost control from day one.

    • LLM Integration
    • RAG
    • Agents
    • Automation
  • 04

    Technical Direction

    Architecture reviews, hiring help, and rescue work on stalled projects. A senior engineering brain on your side of the table.

    • Architecture
    • Audits
    • Rescue Work
    • Team Training

How we work

Four steps,
a demo at every one.

  1. 011–2 weeks

    Discovery

    One to two weeks of focused digging: goals, users, constraints, existing systems. You get a written brief, a scope, and a number.

  2. 022–3 weeks

    Design & Architecture

    UX flows, system design, and a clickable prototype. You approve the blueprint before a single line of production code exists.

  3. 03sprint cycles

    Build

    Two-week sprints with a demo at the end of every one. Working software over status reports. You watch the product grow.

  4. 04ongoing

    Launch & Run

    Deploy, monitor, iterate. We treat go-live as the start of the job, not the end of it. Most of our work happens after launch.

The studio

A small studio, on purpose.

Tessera was founded on a simple observation: most software projects fail from too many hands and too little ownership. So we stayed small. Senior engineers only, no account-manager relay, no junior farm.

The people who scope your project are the people who build it. That is the whole org chart.

Prishtina, Kosovo — working worldwide

  1. 01

    Working software wins arguments

    We demo every two weeks. Progress you can click beats progress you have to believe.

  2. 02

    Boring where it counts

    Proven tools for the foundation, new tech only where it buys you something measurable.

  3. 03

    Your code, your keys

    Every repo, credential, and document belongs to you from day one, in accounts you control.

Technologies we use: TypeScript, React, Astro, Node.js, Python, PostgreSQL, Redis, AWS, Cloudflare, Kubernetes, Terraform, GraphQL
