Custom Software Development

Custom Software Development, When the Problem Is Hard

We don't build generic CRUD apps, and we turn down work we can't do well. We take on the projects other shops quote vaguely: systems with serious data, maps, AI or performance requirements, where getting the architecture wrong is expensive.

  • Senior engineers only
  • Fixed-price milestones, written estimates
  • Boring, maintainable technology

What we take on

  • Data-heavy products: pipelines, search and analytics over millions to billions of records.
  • Geospatial software: maps, routing, geocoding, satellite imagery and location intelligence.
  • AI-integrated applications where the model is one component of a larger, reliable system.
  • Edge and serverless platforms on Cloudflare Workers, D1 and R2, for global low-latency apps at low running cost.
  • Rescues: systems that work in a demo but fall over under real load, real data or a real security review.

What we don't take on

Brochure websites, template e-commerce stores and app clones. There are excellent, cheaper teams for that work and we will happily point you to them. Saying no keeps our engineers on problems where their experience changes the outcome.

How we work

Written estimate

After a scoping call you get a written estimate with milestones, assumptions and risks, so there are no surprises.

Fixed-price milestones

Scoped work is priced per milestone. Ongoing development is time-and-materials with a weekly written report.

Your repos, your cloud

We work in your repositories and accounts from day one. Nothing is held hostage.

Handover built in

Documentation, runbooks and a walkthrough are part of every milestone, not an optional extra.

Our default stack

PostgreSQL (with PostGIS and pgvector) over exotic databases. Python and TypeScript for most services, Rust or Go where performance demands it. Cloudflare's edge platform where global latency and low running cost matter. Proven technology your team can hire for and maintain after we leave.

Typical budgets

Small, well-scoped projects usually start around $15k–30k. Mid-sized builds of two to three months range from $50k to $150k. Large platform projects start around $200k. Tell us your range in the form and we will say honestly whether it fits.

Frequently asked questions

Do you work with early-stage startups?

Yes, when there is a hard technical core. Our fixed-scope sprints, such as Production Gravity, exist for founders who need production-grade foundations in weeks, not quarters.

Can you take over an existing codebase?

Yes. We start with a short paid assessment: architecture review, risk list and a prioritised plan, so you know what you are inheriting before committing to a rebuild or a rescue.

Where is the team based?

In India, working with clients in India, Europe and North America. We agree an overlap window with your team before work starts.

Do you sign NDAs and work under our security policies?

Yes. We routinely work inside client security requirements, including on-prem and air-gapped environments.

Tell us what you need built

Five fields. An engineer reads it and replies within one working day (IST), usually with a first opinion, not a sales pitch.
