Built by Engineers,
Shaped by Experience

Our Story

Built on friendship, forged through experience.

Tweerous was founded by three university friends—Jimmy Ostoich, Evtim Papushev, and Kiril Nozharov—whose partnership began at the American University in Bulgaria and has endured for over two decades.

After graduating, each pursued their own path in software development, gaining deep expertise across different domains:

By 2012, having worked on projects for leading tech companies and FinTech platforms, they recognized an opportunity: to combine their complementary skills and shared engineering philosophy into a high-grade consultancy where quality, precision, and personal accountability would always come first.

The foundation of friendship that began at university has proven to be Tweerous' greatest strength—enabling honest communication, shared values, and a level of trust that translates directly into how we work with clients.

Our Mission

To transform complex business ideas into reliable, elegant, and enduring software systems.

We believe the best technology quietly amplifies business potential—it doesn't complicate it. Our mission is to turn ambitious concepts into operational, scalable, and maintainable digital platforms.

Every solution we deliver is guided by three principles:

  1. Precision – Clean architecture, measurable performance, and long-term reliability
  2. Partnership – Transparent collaboration and direct access to senior engineers
  3. Permanence – Systems designed to evolve with your business, not expire with trends

Our Philosophy

Founder-Led Engineering

Every project we take on is personally overseen by our principals—no managerial layers, no dilution of responsibility. Clients work directly with decision-makers who also write the code and design the architecture.

Perfect Technology Fit

We select technologies based on the problem, not the trend. Whether it's Swift, Rust, Node,js, PostgreSQL, Vue.js, React.js, Next.js, or distributed microservices, we engineer each layer for efficiency, security, and clarity.

Quality Over Volume

We deliberately remain small—taking on fewer projects, but giving each one full focus. Our clients stay with us for years because we treat their systems as our own.

Collaborative Expertise

For specialized domains like cloud infrastructure, DevOps, and machine learning, we work closely with trusted partners who share our commitment to excellence—ensuring you receive best-in-class solutions across all technical disciplines.

Our Expertise

Tweerous operates at the intersection of software development and infrastructure engineering, covering the full lifecycle of digital systems.

Our combined experience covers finance, aviation, tourism & travel, and waste management sectors—environments where security, uptime, and accuracy are non-negotiable.
