Platform Extensions · Apex and LWC built to survive real data volumes
Salesforce development that holds up at production data volumes.
Custom Salesforce development — Apex, Lightning Web Components, integrations and AppExchange packages built to governor limits and real bulk patterns.
Delivered from our Chennai and Bengaluru studios — to clients across India and overseas.
// The problem
It worked in the demo. Then a data load hit two hundred records.
Salesforce customisations rarely fail at the point they are built. They fail three months later — when a bulk import trips a governor limit, when a trigger cascades in a way nobody modelled, or when a consultant's work collides with a sharing model that was never fully documented.
By then the org has accumulated several people's customisations, minimal test coverage, and a general reluctance to change anything. The platform is capable; the implementation has become fragile.
Does any of this sound familiar?
Failures on bulk operations
Code that handles one record cleanly and fails on a data load.
Nobody wants to touch it
Test coverage that exists to satisfy deployment, not to catch regressions.
Triggers with unpredictable effects
Cascading automation nobody has mapped end to end.
Integrations that fail silently
One-way calls with no retry, no error handling, and no reconciliation.
What it costs to leave this alone
A fragile Salesforce org taxes every future change. Work that should take days takes weeks because nobody is confident what will break — and the fear compounds as more customisation lands on top.
// How we fix it
Our approach to Salesforce Extension Development
We build to bulk patterns and governor limits from the first line, because retrofitting that is far more expensive than doing it correctly. Lightning Web Components that perform, integrations with retry and reconciliation, and customisations that respect your sharing model rather than working around it.
Test coverage exercises real scenarios and bulk conditions rather than hitting a percentage. That is what makes the next change safe — and it is the difference between an org you can develop and one you are afraid of.
Talk to us about your project// What changes
The return, in plain terms
What you should expect to be different once this is in place.
Bulk-safe
By construction
Written to governor limits and bulk patterns, so data loads do not break it.
Testable
Real coverage
Tests exercising genuine scenarios, so future changes are safe rather than frightening.
Auditable
Sharing respected
Customisation that works with your security model, not around it.
// What's included
Everything in Salesforce Extension Development
Apex built for bulk
Triggers and classes written to bulk patterns and governor limits — not code that works on one record and fails on two hundred.
Lightning Web Components
Modern, performant custom UI matching Salesforce design conventions and behaving properly on mobile.
Integration engineering
REST and platform-event integrations with retry logic, error handling and reconciliation rather than optimistic one-way calls.
Sharing and security model
Customisations that respect your sharing rules and field-level security rather than working around them.
Test coverage that means something
Tests exercising real scenarios and bulk conditions, not the minimum needed to deploy.
AppExchange packaging
Security review preparation and packaging if you intend to distribute commercially.
// Who this is for
Is this you?
Companies with a fragile Salesforce org

ISVs building for AppExchange

// Problems we've solved
From challenge to result
Representative engagements, described in terms of what changed for the business.
The challenge
Nightly data loads failed intermittently, and nobody could reliably reproduce the error.
What we did
Audited the trigger framework, rewrote the logic to bulk patterns, and added tests covering bulk and mixed-DML scenarios.
The result
The loads ran cleanly, and the failure mode became reproducible in tests rather than discovered in production.
The challenge
An integration silently dropped records when the external system was briefly unavailable.
What we did
Rebuilt it with queued retries, error surfacing and a reconciliation report comparing both sides.
The result
Failures became visible and recoverable rather than discovered during a quarterly audit.

// Questions
Salesforce Extension Development — FAQs
Almost always governor limits and non-bulkified code. Logic written to handle one record at a time fails when a data load processes two hundred. Writing to bulk patterns from the start costs no more and prevents the entire class of failure.
Yes — auditing and remediating inherited orgs is a common engagement. We assess triggers, flows and customisations, identify what is causing failures, and stabilise before adding anything new.
Both, and choosing correctly matters. Flow is right for a great deal of automation and is maintainable by admins. Apex is warranted for complex logic, bulk processing and integrations. Using Apex where Flow would do makes your org harder to maintain.
Yes. The review is thorough and rejects on specific, predictable grounds — CRUD/FLS enforcement, SOQL injection, sharing violations. Designing against it from the start is far cheaper than remediating afterwards.
