Hire CRM developers who start from your records, not a contacts table
As of October 2026, our engineers have completed 41 CRM projects. Most of those systems track a trading account, a job candidate or a patient chart, or a sales deal. When you hire CRM developers, that central record decides who fits the work.
What is the main record in your CRM?
Salesforce, HubSpot and Dynamics 365 are built around contacts, companies and deals. That model suits a sales team moving opportunities through stages. It strains when your business manages something else: a brokerage account with trading permissions, a candidate placed with several clients, or a clinic visit with an insurance claim attached.
Two expensive mistakes follow from the wrong call. A company forces its own record into a platform, and its rules end up in custom fields that no report can read together. Or a team builds its own CRM when contacts and deals were enough, then rebuilds the email sync, permissions and change history the platform already had. Cortance matches CRM developers on the records they have modelled before. A brokerage meets engineers who built account systems, and a team on Dynamics 365 meets engineers who extended it.
CRMs our engineers built around a client's own record
Ivan V. designed a CRM for brokers and proprietary trading firms where the central record is a trader account. He connected it to the Takion, Silexx and DAS trading platforms through APIs and webhooks. Opening an account and managing its subscriptions for platform access, market data and execution rights had been manual work, and his system automated it. He also moved the existing traders into the new CRM, together with the brokers and firms above them.
Alex St. was the lead PHP developer on RECMAN, a CRM for recruitment and staffing agencies built around candidate search and invoicing. In a team of ten developers, he planned the fixes for database weaknesses and XSS vulnerabilities. He also designed the marketplace module, with a REST API that lets other tools integrate with the CRM.
Ivan S. built a CRM for field sales representatives on .NET, with warehouse stock, delivery route planning and a mobile mode, integrated with Salesforce. One API layer serves the web client, the mobile app and a Telegram bot, so every channel applies the same business rules.
AI jobs with the records your CRM keeps
A growing share of the requests Cortance receives are process automation and AI agents. In a CRM, those features depend on the same data model. A transcript of a treatment session is useful when the session is a record in its own right, with a patient, a doctor, and a date. Saved as free text on a contact, it cannot be filtered, reported on or reviewed. Alex St. worked on EDUCTO, a treatment CRM for doctors who work with children with special needs, where he built session records with live audio recording and speech-to-text.
The same applies to AI that talks to customers. Dmitry A. connected an AI support bot to an operator CRM. When the bot cannot answer, the conversation lands in the operator queue with its message history. He replaced automatic assignment with a queue where operators claim dialogues, after remote operators on unstable connections kept receiving chats they could not pick up. In project histories like these, we look for where AI output lands and who handles what it cannot.
Send us your main record and the systems around it
Tell us what your CRM tracks or should track, which platform you run today, if any, and which systems it exchanges data with: billing, accounting, telephony, email or a mobile app. We send matched CRM developer profiles within 30 minutes, at a typical $29-42 an hour, and the developer you choose can start within 2 days.

Where CRM work in our network goes beyond contacts and deals
Engineers in Cortance's network have built and extended CRMs for clinics, insurers, car dealers, field sales teams and marketing teams.
Dental clinic CRM around the patient chart
Ann D. built front-end features for a dental clinic CRM whose one-page chart shows a patient's clinical information at a glance, with health ledgers, insurance plans and lab requests attached. React, TypeScript and GraphQL.
Insurance CRM with calls inside it
Arevik S. worked on a CRM for US insurance companies with one-to-one, app-to-app and conference calls through Twilio on the front end and back end, plus Stripe payments. She was responsible for one of its microservices.
Car dealership CRM on a phone
Victoriia S. led the mobile app of a CRM for car dealerships from its first version: warehouse stock, sales tracking and staff productivity, built in Flutter with BLoC and Firebase.
Salesforce data on an offline iPhone
Severyn K. worked on an iOS app for medical sales reps that builds its screens and a local SQLite database from Salesforce data. Reps create orders and customers offline and sync later, and admin changes in Salesforce reach the app on the next sync.
Email activity captured into the CRM
Ihor O. worked on an Azure-hosted product that captures email activity into the CRM through an Outlook and Gmail add-in, with an admin UI for sync statistics and user management.
A marketing CRM moved off a monolith
Dmytro V. worked on a CRM that targets customer groups for marketing campaigns. He helped move its legacy features from an old .NET monolith to .NET and Python microservices on Google Cloud, with Snowflake for the data.

Choosing a CRM developer: the work, the skills and the checks
Three kinds of CRM work, three different skill sets
CRM projects fall into three kinds of work, and each calls for a different developer.
Platform work happens inside a vendor's CRM. On Salesforce, that means Apex, Flow and Lightning Web Components. On Microsoft Dynamics 365, it means C# plug-ins, automation flows and Power Apps. The developer needs the platform's limits and deployment habits more than a broad framework stack.
A custom CRM is a product of its own, built on a web framework such as Laravel, Node.js, .NET or Django with a relational database underneath. The developer designs the data model, the permissions and the history of changes, because no vendor ships them.
Integration work connects a CRM to billing, accounting, telephony, email or a mobile app. It is API and queue work: webhooks, retries and a rule for which system wins when two of them disagree. Many projects need two of the three kinds, and a brief that names them gets a sharper match.
Skills that separate a CRM developer from a general web developer
A general web developer can build the forms and tables of a CRM. A CRM developer also plans for what years of use do to customer data. Three skills show the difference.
The first is permissions. Sales, support, finance and managers see different parts of the same customer, and one wrong rule shows a margin or a medical note to the wrong team. A good candidate can explain the access model of a CRM they built, not only its screens.
The second is duplicates. The same customer arrives through a web form, a spreadsheet import and a phone call. Someone has to decide which record survives a merge and what happens to the notes and deals attached to the other one.
The third is the history of changes. Disputes about a price or a promise end with the question of who changed a field and when. A CRM that keeps no history leaves that question without an answer.
Moving records out of an old CRM or a spreadsheet
A CRM migration fails when history arrives without the links that gave it meaning: notes detached from the deal, invoices detached from the customer. Three decisions come before the move. Map every old field to its new owner, or decide to drop it. Keep the old record IDs, so history can be linked again and checked after the import. Run both systems side by side for a short period and compare the totals.
Ask a candidate how they kept history linked in a past migration. A specific answer about IDs and reconciliation is worth more than a list of import tools.
What to check in a CRM developer's past projects
Ask about one CRM the candidate built or changed, and listen for the record at its center. A strong answer names that record, explains who could see and edit it, and describes one sync that failed and how anyone noticed. Weak answers stay on screens and fields.
Three answers are red flags. The candidate plans to fit every rule into custom fields before asking how reports will read them. Nobody owned the integration after launch. Duplicates were cleaned once, with no rule for the new ones that keep arriving.
Why demand for CRM work keeps growing
Salesforce leads the CRM market with a 20.0% share of 2025 revenue, according to IDC's Worldwide Semiannual Software Tracker from April 2026. The other four fifths of that revenue go to other vendors, before counting the CRMs companies build for themselves. Each of those systems needs developers who can change it.
Automation adds a second source of demand. AI agents that qualify leads or answer customers read and update CRM records, and they work only as well as the data model under them. A CRM with a clear model for its main record is where that work starts.
