Choose your situation

A short path for your task — pick what fits best.

What I solve

If the CRM is unstable, data diverges, an integration fails without a clear error, or the old code is scary to touch — I first find the cause, then propose a safe fix plan.

Leads are created as duplicates Deals are not linked to leads Robots fire at the wrong stage Business processes hang REST requests overload the portal Sync works "sometimes" Impossible to understand the cause of an error No exchange history Reports do not match reality The old code is scary to touch

Ready-made solution paths

Some tasks ship faster on a proven skeleton.

Examples of tasks I have solved

Without disclosing clients: problem, approach and operational result

CRM and lead/visit duplicates

Problem: Duplicate leads, deals and contacts; managers lost visits and reconciled data manually.

What I did: Set up rule-based deduplication, data normalization and mobile visit forms.

Result: Managers stopped reconciling visits manually, the database was cleaned of duplicates.

Bitrix24 D7, REST, PHP, MySQL, cron 1–2 weeks

Bitrix24 ↔ MoySklad integration

Problem: Products, stock and orders diverged between the CRM and the warehouse.

What I did: Built two-way sync with mapping, retries, error handling and logging.

Result: An exchange history appeared: it is clear where and why sync fails.

Bitrix24, MoySklad API, PHP, queues, logs 1–3 weeks

HR automation and candidates

Problem: Hiring was manual, candidates from HeadHunter/Huntflow did not reach the process.

What I did: Integrated HH and Huntflow, auto-creation of candidates, HR processes and notifications.

Result: Candidates enter the funnel automatically, less manual transfer.

Bitrix24, HH/Huntflow API, webhooks 1–2 weeks

Client checks via external services

Problem: Client checks (scoring, government and banking) were done manually.

What I did: Connected TrustMe / ADATA / PKB and OTP, auto-checks right in the card.

Result: A check in seconds right in the card, a single process.

PHP, REST, TrustMe/ADATA/PKB, OTP 1–2 weeks

FAQ

Do you work under a contract?

Yes, officially as a sole proprietor: contract, invoice and closing documents.

Do you work with the Bitrix24 box (D7)?

Yes. I customize the boxed version: modules, business processes and direct integrations on D7.
