How we work
01
One project has our attention at a time.
We take on a small number of builds so each one gets a whole brain rather than a slice of one. That is why estimates hold, why the person answering your message is the person writing the code, and why we turn down work that would spread us thin.

02
The unglamorous parts get built too.
Tests, migrations, error handling, access control, backups, the rollback path. The work that never shows up in a demo is the work that decides whether the product survives its first real month. We do not quietly skip it to hit a date.
Tests, CI, monitoring and a rollback plan ship with every build
03
Same standard on week one and week twelve.
A written update every Friday. A staging URL you can click from the first week. Code that looks like it was written by one person because the conventions were decided before the first commit. No sprint where quality quietly drops because the deadline moved.
Weekly demos and a written update, every week, without being chased
Take a single piece or hand over the whole build. Most clients start with one service and keep us on a retainer once the product is live.
The whole product, from empty repo to store listing.
Full product builds — from empty repo to live, monitored deployment.
Cross-platform mobile apps that ship to both stores from one codebase.
Storefronts, carts, checkout and admin — tuned for conversion.
Courses, cohorts, assessments and progress that actually tracks.
Retrieval and agents built with limits, tracing and evaluation.
The layer underneath — APIs, data, permissions, infrastructure.
Permissions that hold up to an audit, not just to the happy path.
Stripe, PayPal, Razorpay and subscriptions — built to reconcile.
FastAPI and Node services with real auth, jobs and observability.
SQL, NoSQL, indexes, migrations and a cache layer that stays correct.
CI/CD, containers and infrastructure as code on AWS, Azure or Vercel.
Retainers for updates, monitoring, fixes and steady improvement.
4 of these ship as fixed-price packages you can order outright — see the packages. The rest are quoted after a scoping call.
Every screenshot below is a capture of the running interface. Open any one for the constraint behind it and the scope that was delivered.
A car rental booking platform — accounts, a vehicle catalogue, and a booking form that captures type, locations and dates in a single pass.
A service business site built around one job: turn a visitor into a booked call-out, on a phone, in under a minute.
A clothing storefront with category browsing, a cart that survives navigation, and a best-sellers carousel on the landing page.
Most of our clients arrived after a bad experience elsewhere. These four commitments are what we changed.
You approve a written scope and a number. Change requests are quoted separately, so the invoice at the end matches the one at the start.
A staging URL from week one and a demo every Friday. Progress you can click, not a status percentage in a spreadsheet.
Tests, CI, monitoring, backups and a rollback path ship with the build. A demo that cannot survive real traffic is not finished.
Documentation and a walkthrough at the end of every project, whether or not you retain us. Lock-in is not our business model.
You approve a scope and a number before anything is built, and you see working software every week after that.
We walk through what you are building, who it is for, and what has to be true for the project to count as a success. You leave with a rough scope, a rough number and an honest read on whether we are the right team.
You get: Written scope summary within 24 hours
A written proposal: milestones, deliverables, timeline, price and explicit exclusions. No hourly surprises — you approve a scope, and changes to it are quoted before any work starts.
You get: Proposal, contract and milestone schedule
Data model, API contracts and infrastructure plan on paper before code. UI work starts in Figma so you approve screens rather than reviewing half-built pages.
You get: Architecture doc, ER diagram, approved designs
Working software every week on a staging URL you can click through. A short written update each Friday: what shipped, what is next, anything blocking. You are never guessing where the project stands.
You get: Staging environment, weekly demo and written update
Automated tests in CI, load and failure-path testing, security review, performance budgets, then a rehearsed deploy with a rollback plan. Launch day is uneventful by design.
You get: Test suite, CI pipeline, production deployment
Documentation, a recorded walkthrough and a 30-day warranty on everything we shipped. If you want us to keep operating it, a maintenance retainer picks up from there.
You get: Docs, walkthrough video, 30-day warranty
We pick tools with long support horizons and hiring pools, so your team can maintain what we hand over.
Fixed scope, fixed price, from $30. Anything larger — a multi-month product, an agentic system, ongoing maintenance — is scoped in writing and quoted against it.
An assistant that answers from your own documents and cites the passage it used, instead of a general-purpose model guessing at your business.
from $1083–14 days
React on the front, FastAPI and a database behind it, deployed to your own cloud account with the source in your repository.
from $963–14 days
For an app that already works locally and needs to be live, on your infrastructure, with a deploy path your team can repeat.
from $301–5 days
9 packages in total, with the delivery time and revision count on each.
Architecture decisions, payment edge cases and performance work, written up the way we would explain them on a call.
Why naive vector search underperforms, chunking that follows document structure, hybrid retrieval with reranking, and the evaluation set you need before tuning.
