Capabilities

Building software since 1999. Here is what we can do for you.

KodeSquadra is led by an engineer who has shipped production software since 1999: for jewellers, exporters and manufacturers in the 2000s, for clients who stayed for years, and for our own products today. Our longest client relationship is in its fifteenth year and still running. Most of that work sits under NDA, so this page describes it without names. It is the long answer to “what can you actually do?”, written for agencies and businesses deciding whether to work with us.

  • 1999building software for clients since
  • 15 yrsour longest client relationship, still running
  • 3 + 3products we run, and client sites you can open
  • 1,000+automated tests on the platform we maintain

Product types

What we build

Each type below is something we have shipped and kept running, not a menu of things we would like to try. The proof line points to the work it comes from.

SaaS products

Multi-tenant platforms with public booking, subscriptions, client records, messaging and billing, including UPI.

Proof: UnifiedSelf, live for therapists in India.

Business platforms & internal tools

Work management, workflows, org charts, documents, learning modules, compliance and asset tracking for companies of any size.

Proof: the platform we have engineered solo for over a decade.

Shop-floor & operations software

Production and packing planning, shift and item tracking, stock, and label printing on the machines where the work happens.

Proof: production screens in daily use at a wholesale business.

ERP integration & data platforms

Mirroring an ERP database into Postgres on a schedule with reconciliation, read APIs on top, and dashboards or Power BI fed from it.

Proof: a nightly Dynamics AX mirror serving live dashboards.

Mobile & desktop apps

.NET MAUI apps for Android, iOS and Windows sharing code with the web app; Windows desktop applications and services when that is the right fit.

Proof: a MAUI companion app to that platform, and twenty years of Windows software before it.

Websites that convert

Server-rendered sites with technical SEO, structured data, analytics with consent handling, lead capture, admin panels and knowledge-base chatbots.

Proof: this site, our own product sites, and SHA Career Hub and SHA Infotech, rebuilt in a week.

AI-assisted features

Drafting text, summarising records, analysing company data, and chatbots that run on a knowledge base and switch to an LLM by configuration.

Proof: shipped in that platform, in UnifiedSelf, and in SHA Career Hub's chatbot.

Legacy modernisation

VB6, classic ASP, Windows Forms and .NET Framework systems moved to .NET 10 and Blazor; SQL Server data moved to Postgres with an import pipeline, not a big-bang rewrite.

Proof: one product carried from Windows Forms to ASP.NET to Blazor to MAUI, with its data intact.

Finance & compliance software

GST invoicing with LUT exports and IGST or CGST+SGST splits, GSTR-1 export, TDS, credit notes, payment tracking, and two-way accounting integrations.

Proof: our own GST invoicing tool, and accounting and payroll software built earlier.

Selected work

What each engagement involved

Most client engagements since 2005 have been under NDA; where we may name the client, we do. What follows is what each one involved, which is what you need to judge whether we can do yours.

A work-management platform, engineered solo for over a decade

For a partner of more than ten years we are the entire engineering team: backend, frontend, database, mobile app, integrations, hosting and releases. The product covers tasks, workflows, org charts, chat, documents, learning modules, compliance and assets for companies of any size, in two languages. Over the years it moved from Windows Forms to ASP.NET to Blazor, and from SQL Server to Postgres, without losing its data or its users.

Today it ships as a web app and a MAUI app for Android, iOS and Windows, backed by more than a thousand automated tests. It integrates with payments, email, calendars, SMS and an external accounting system, and its AI features draft text, summarise records and analyse company data.

  • .NET 10
  • Blazor
  • MAUI
  • PostgreSQL
  • SignalR
  • AI features
  • Sole engineer

Shop-floor screens and an ERP data platform for a wholesale business

The same partner’s wholesale business has run on Dynamics AX since 2009. We mirror its production database into Postgres every night with reconciliation and repair, expose read APIs on the mirror, and feed Power BI from it. On top of that data we built production and packing planning screens used on the shop floor every day, a small label-printing service on each factory PC driving industrial printers, and dashboards for purchasing, stock, production and waste. Moving the business off AX onto our own system is the next step under discussion.

  • Dynamics AX
  • SQL Server
  • PostgreSQL
  • Blazor Server
  • Power BI
  • Label printers
  • IIS

Complete production software for a food producer, used by 100+ staff

A company producing food for businesses and delivering it daily or on schedule needed one system for recipes, costing, purchasing, deliveries, labelling and invoicing, with two-way integration to its accounting package. We built it as a Windows application plus a set of utilities, services and web tools that ran across its outlets. More than a hundred staff used it daily for years.

  • Windows Forms
  • Windows services
  • ASP.NET
  • SQL Server
  • Accounting integration

Accounting, invoicing, payroll and budgeting software, four years

As part of a large team at a finance-software vendor, we spent four years on a Windows and SQL Server product used by the vendor’s own staff and its customers. Most of our effort went into an extension built for one of the vendor’s clients.

  • Windows
  • SQL Server
  • Payroll
  • Budgeting
  • Large team

SHA Career Hub and SHA Infotech: two sites and a chatbot, in one week

SHA Career Hub, an IT training institute, and its parent company SHA Infotech came to us by referral. We reviewed their existing sites, wrote a competitor analysis and a conversion action plan, rebuilt both sites with admin panels, lead capture and a blog with structured data, and added a chatbot that answers from a knowledge base and switches to an LLM by configuration. Delivered in a week.

  • ASP.NET Core
  • SQLite
  • Claude API
  • Technical SEO
  • Competitor analysis

GST invoicing for an exporting consultancy

Built for our own use and live today: invoices with financial-year numbering series, zero-rated exports under LUT, IGST or CGST+SGST as the case requires, PDF invoices with amount in words, payment tracking with days-late and short-payment analysis, credit notes, TDS, GSTR-1 export sheets and exchange rates compared across RBI and ECB feeds.

  • Blazor
  • PostgreSQL
  • GST
  • PDF generation
  • FX rates

Retreat booking with online payments

A booking site for a residential retreat: Razorpay order creation and signature verification, and enquiry and collaboration forms captured straight into Google Sheets. A family project, no longer active.

  • Razorpay
  • Google Sheets
  • Minimal API

1999 – 2010

The early years

A decade of software for businesses of every kind, before the long engagements began. The code is long gone; the domain knowledge is not.

  • An invoicing system for a jewellery design house, our first paid project, in 1999.
  • A pricing engine for a jewellery manufacturer: raw-material prices, manufacturing charges under several heads, mark-ups per process and per-batch parameters, resolved into a final selling price.
  • Export documentation software generating the complete document set for a garment exporter.
  • VAT-compliant invoicing for pharmacies, computer hardware retailers and other shops when VAT arrived.
  • Advertising-agency software: where each advertisement runs, money received and recurring orders.
  • A manufacturing data-processing system on COM/DCOM for a large company, running across three or more branches with hundreds of workers.
  • Magazine advertisement publishing software.
  • Windows utilities on system APIs: Outlook mailbox recovery and repair, and audio generation.
  • Accounting and automation applications for several businesses, and a photo upload-and-display web app when the web was new.

Working together

Three ways to engage

Projects are quoted as a fixed price or a monthly retainer. Ask for a written estimate; it is free, specific, and includes whether you should build it at all.

For agencies

Senior white-label capacity for the projects your team cannot take on. You keep the client and the relationship; we deliver under your name and under NDA, which has been our normal since 2005.

  • Fixed scope or monthly
  • No management overhead
  • Your repositories, your accounts

For businesses

A fixed price against a written estimate, starting with the smallest version of your idea worth building. You own the code, the designs and the infrastructure from day one.

  • Written estimate before any work
  • Working software every week
  • Plain-language updates

Retainer

For products that need steady engineering: a monthly retainer covering improvements, monitoring, maintenance and support, with a predictable invoice.

  • Predictable monthly cost
  • Pause or stop any month
  • The same engineer throughout
