Custom software development
Full-lifecycle product engineering — discovery, architecture, build, launch and operations — for web, mobile and backend systems.
REPSOG LTD partners with operators, founders and CIOs to design, build and operate the software, cloud platforms and cybersecurity systems their organizations depend on.


REPSOG LTD was founded on a simple idea: serious software requires senior people, disciplined process and a refusal to ship anything we wouldn't operate ourselves. We embed deeply with our clients to build systems that scale and survive.
No layered juniors. Every engagement is led by experienced architects and engineers.
We optimize for shipping the right thing — measured by business impact, not story points.
From greenfield product build to platform modernization, we cover the full software lifecycle.
Full-lifecycle product engineering — discovery, architecture, build, launch and operations — for web, mobile and backend systems.
AWS, Azure, GCP, Kubernetes, Terraform, observability and SRE.

Pipelines, warehouses, applied ML and LLM integrations.
Internal tooling, RPA and workflow orchestration.
Architecture reviews, technology strategy and CTO advisory.
We choose technologies for longevity, performance and operational sanity — not novelty.

Architects and senior engineers on every engagement, end to end.
We measure ourselves by what ships and what stays up — not hours billed.
Threat modeling and least-privilege baked into delivery, not bolted on.
Weekly demos, public roadmaps, clear costs, no surprises.
Observability, runbooks and on-call discipline as a first-class deliverable.
Most engagements last years. We're built for sustained collaboration.
Distributed teams across Europe with overlap for North American clients.
We integrate AI where it changes outcomes — not for the slide deck.
Five phases, continuously revisited. No theatre, no waterfall — just disciplined iteration.
We map your goals, constraints, users and technical landscape.
We propose a pragmatic architecture, risks called out, trade-offs explicit.
Senior engineers ship in weekly increments with demos and live environments.
Performance, security, observability and operational readiness before launch.
We run, monitor and evolve the system as a long-term partner.
