Web apps and SaaS platforms
Multi-tenant products with billing, roles, audit trails and the admin tooling you need on day one. Built to be operated, not just demoed.
- React, Next.js, Astro
- Auth, billing, multi-tenancy
- Design systems and accessibility
One crew · One plan · Shipped
The crew you call when the software has to ship.
dalidev is a small team of senior engineers with FAANG and Fortune 500 backgrounds. Each one a specialist, one plan, one accountable team. Web, mobile, backend, AI systems and the cloud underneath them, built end to end and handed over in a repository you own.

- Senior engineers only. No juniors on your project.
- Direct access to the people writing the code.
- Fixed scope or time and materials, priced in writing.
- Remote, overlapping your working hours.
What we build
Six things we do well, from a blank repository to a system your team operates. Each one staffed by people who have run it in production before.
Mobile apps
iOS and Android from one codebase where that makes sense, native where it does not. Offline-first, push, in-app purchases, store submission handled.
- React Native, Flutter
- Swift and Kotlin when needed
- Release pipelines to both stores
Backend, APIs and microservices
Services that are boring to run: typed contracts, idempotent endpoints, queues where they belong, and the tests that let you deploy on a Friday.
- REST, GraphQL, gRPC
- Event-driven and queue-backed
- Postgres first, the rest on merit
AI and agentic systems
LLM products that hold up in production: agents with tool use, retrieval that cites its sources, evals you can run in CI, fine-tuning when prompting runs out.
- Agents, tool use, MCP integrations
- RAG and vector search
- Evals, guardrails, fine-tuning
Cloud, DevOps and Kubernetes
Infrastructure as code from the first commit: clusters that upgrade without a weekend, fast CI/CD, observability that pages the right person, and a bill you can explain.
- Kubernetes, Terraform, Helm
- CI/CD, GitOps, ArgoCD
- Observability and cost control
Data engineering and ML pipelines
Pipelines that are reproducible and cheap to re-run: batch and streaming ingestion, warehouse modelling, feature stores, and model training that ships to serving.
- Kafka, ClickHouse, dbt
- Airflow, Spark, streaming
- Training to serving, monitored
Something else? We take on any project where good engineering matters: legacy modernisation, performance work, architecture and security audits, embedded systems, trading systems, internal tooling. If you are not sure it fits, a 30-minute call settles it.

How we work
Four steps, no account managers in between. The people on the call are the people who write the code.
Call
A free 30-minute scoping call. You describe the problem; we ask the questions that decide the shape of the build, and tell you if we are the wrong crew for it.
Proposal
Scope, timeline and price in writing within days. Fixed price when the problem is well defined, time and materials when it is still moving.
Build
You see the repository from day one and a working demo every week. Decisions get written down. If something turns out harder than planned, you hear it that week, not at the deadline.
Launch and support
Handover with documentation your own team can run from, runbooks for the parts that page people, and an optional retainer if you want us on call.
Why a small crew
The reason to hire a small senior team instead of a large agency is not price. It is that nothing gets lost between the person who understood the problem and the person who solved it.
Senior only
Everyone on your project has shipped and operated production systems for years. No bench of juniors learning on your budget, and nobody to escalate to: you are already talking to them.
Robust and efficient by default
Tests that catch regressions, observability that explains incidents, performance budgets that stop slow code getting merged. Not an extra line item: it is how the software gets built.
We say no
If a feature should not be built, a stack is the wrong one, or a deadline is fiction, we say so before you pay for it. A smaller, correct system beats a larger one that nobody trusts.
You own everything
The code, the repository, the infrastructure accounts and the documentation are yours from the first commit. No lock-in, no proprietary framework, nothing you cannot hand to the next team.
Questions we get asked
How do you price?
Two ways. Fixed price when the scope is clear enough to commit to: you get a number, a timeline and a definition of done in writing. Time and materials when the scope is still being discovered or you want a crew embedded for a period, billed weekly against hours you can see. We tell you on the scoping call which one fits.
Do you sign NDAs?
Yes, before the scoping call if you prefer. We will sign a reasonable mutual NDA of yours or send ours. Work product is assigned to you in the contract.
Can you work with our existing team?
Yes, and it is often the best setup. We work in your repository, follow your review process and join your standups. We can own a workstream outright, pair with your engineers, or take the parts your team does not have time for.
What stack do you use?
Yours, if you have one. On greenfield work we default to TypeScript or Python with PostgreSQL, containers on Kubernetes or a managed platform, and Terraform for infrastructure, and leave that default when the problem asks for Go, Rust, native mobile or something else. The full list is under Technologies above.
How fast can you start?
Usually within two to three weeks of a signed proposal, sooner for a small, well-defined piece of work. The scoping call can happen this week.
Start a project
Tell us what you are building. An engineer replies within one business day with a time for a free 30-minute scoping call.
Prefer email?
contact@dalidev.comSame people, same one-business-day reply. If it is urgent, say so in the subject line.
Scoping call
Free, 30 minutes, with an engineer. You leave with a view of scope, risk and rough cost, whether or not you hire us.
Hours
Remote, overlapping your working day in European and North American time zones.
