Capabilities

Senior teams that ship

One partner to discover, design and build software that moves the needle.

Core

Custom software development

Web products and APIs built to scale. TypeScript, Go, Rust where latency matters.

AI / ML engineering

Production pipelines, RAG, evaluation and fine-tuning. Not demos — systems.

Platform engineering

Kubernetes, observability, DX. Teams that ship faster with fewer incidents.

Sprint 2w

Product discovery

From fuzzy idea to executable spec in 2 weeks. Research, prototyping, validation.

Technical due diligence

Audits for PE / VC. Architecture, tech debt, team, hidden risks.

Methodology

A short path from brief to deploy

01

Discovery

Stakeholder workshops, mapping of existing systems and definition of measurable success. 1–2 weeks.

02

Design

Architecture, UX flows, high-fidelity prototypes. Stack decisions documented as ADRs.

03

Build

Short sprints, weekly demos, continuous deploys from day one. Zero surprises at the end.

04

Launch & iterate

Phased rollout, active monitoring, transition to your team with playbooks and handover sessions.

Client voice

What founders say after working with us

Working with Vildez is the first time a consultancy delivered what it said it would, on the timeline it said, with the quality our senior engineers respected. We kept them past the initial contract.

María Castañeda

CTO, Arcadia Fintech

They're not freelancers in suits. They're a team that walks in, understands the business, and leaves the codebase in better shape than they found it.

Tomás Vidal

VP Eng, Lumen Health

The depth of their discovery phase saved us three months of building the wrong thing.

Irene Lobo

Founder, Cedro Retail

FAQ

What every CTO asks before signing

We work by outcomes: we define concrete deliverables with dates, we don't sell hours. Typical contracts run 8–24 weeks with optional extensions. For discovery we offer fixed 2-week sprints.
