senior engineers · end to end

Software that stays fast as you grow.

lognsoft is a small team of senior engineers with FAANG and Fortune 500 backgrounds. We build the software you need, end to end: web and mobile products, backends and APIs, AI systems, cloud infrastructure.

Robust, efficient, and built to scale like O(log n): the cost of growing should flatten, not climb.

  • Senior engineers only. No juniors on your project.
  • Direct access to the people writing the code.
  • Fixed scope or time and materials, your choice.
  • Remote, overlapping your working hours.

services

What we build

Any software you need, from the first commit to the first million requests. One team, the whole stack, no handoffs between agencies.

  • 01 / web

    Web apps and SaaS platforms

    Multi-tenant products, dashboards, customer portals and internal tools. Typed front to back, tested, and shipping behind CI from the first week.

  • 02 / mobile

    Mobile apps

    iOS and Android, native or in one codebase with React Native or Flutter. Store releases, crash-free rates you can quote, offline-first where the product needs it.

  • 03 / backend

    Backend, APIs and microservices

    REST, gRPC and GraphQL services, event-driven architectures, queues, and the unglamorous parts done right: auth, rate limits, idempotency, migrations.

  • 04 / ai

    AI and agentic systems

    LLM applications, agents with tool use, RAG over your data, fine-tuning where it pays off, MCP integrations, and evals so you know when a change makes it better or worse.

  • 05 / cloud

    Cloud, DevOps and Kubernetes

    Kubernetes clusters that stay boring, Terraform for everything, CI/CD pipelines, observability with real SLOs, and cloud bills that go down instead of up.

  • 06 / data

    Data engineering and ML pipelines

    Warehouses, streaming pipelines, feature stores, model training and serving. Correct data first, fast data second, dashboards last.

Something else? We take on any project where good engineering matters: legacy modernisation, performance work, audits, embedded, trading systems. If it has to be correct and fast, it is our kind of work.

process

How we work

Four steps, each with something you can hold: a call, a written proposal, a repository, a running system.

  1. step 1

    Call

    A free 30-minute scoping call. You explain the product and the constraints; we ask the questions that decide the architecture.

  2. step 2

    Proposal

    Scope, timeline and price in writing within days. Fixed scope or time and materials, you pick. Any change after that is agreed in writing.

  3. step 3

    Build

    Weekly demos of working software. You see the repository from day one, with tests, CI and a preview deploy for every change.

  4. step 4

    Launch and support

    Handover with documentation and a runbook, not a zip file. An optional retainer for the months after, if you want us close.

principles

Why teams hire us

Not for the lowest hourly rate. For software that is still cheap to run and easy to change two years in.

  • Senior only.

    Everyone on your project has built and operated production systems for years. No juniors learning on your budget, no account managers between you and the engineers.

  • Robust and efficient by default.

    Tests, observability and performance budgets are part of the definition of done, not a later phase. We design for the load you will have, not only the load you have today.

  • We say no.

    If a feature should not be built, or a simpler path exists, we say so before you pay for it. Judgement is the larger part of what you hire.

  • You own everything.

    The code, the repository, the infrastructure and the accounts are yours from the first commit. Leaving us is easy by design.

faq

Questions we get on the first call

How do you price?

Two ways: a fixed price for a fixed scope when the requirements are clear, or time and materials billed weekly when they are still moving. Both are quoted in writing after the scoping call, and we tell you which one fits before you choose.

Do you sign NDAs?

Yes. Send yours or use ours; we sign before the first detailed conversation. What you share in the scoping call is treated as confidential whether or not an NDA is in place.

Can you work with our existing team?

Yes, and we do it often: owning one workstream end to end, pairing with your engineers, or taking a platform or infrastructure piece off their plate. We work in your repository, your issue tracker and your review process.

What stack do you use?

Yours, if you have one. We are fluent in TypeScript, Python, Go, Rust, Java, C# and Swift and the ecosystems around them. For greenfield work we recommend a stack based on your team and the hiring market, not on our preferences.

How fast can you start?

Usually within one to two weeks of a signed proposal. The scoping call can happen this week.

Tell us what you are building. The first 30-minute scoping call is free, and it is with an engineer, not a salesperson.

A few lines are enough. Rough numbers on users, data and deadlines let us bring something concrete to the call.

An engineer replies within one business day.
