Answers to the most popular questions
Boxed systems work well as long as your processes match their logic. In Cherkasy I most often see mixed businesses: wholesale plus processing plus retail plus export. In Bitrix24 or RetailCRM these scenarios become an expensive web of workarounds and paid modules. A custom CRM on Next.js and Node.js gives a clean data model for your real process: a funnel with a production stage, separate price lists for wholesalers and gas-station chains, multi-currency for export. You do not pay per user monthly and do not depend on the vendor's roadmap.
For the stack details see CRM, ERP and SaaS.
For agribusiness and manufacturers — like processing plants or agricultural machinery dealers — I build two-way exchange with 1С/BAS via REST API or a middleware bus. The CRM owns sales, contracts and shipments; 1С/BAS remains the core of accounting and warehouse. Every sync is logged, with manual rollback and a discrepancy dashboard so the accountant trusts the numbers.
I start with critical documents: invoice, delivery note, return, reconciliation act. Then, if needed, production orders, specifications, batch tracking. More on the approach in Web Development.
Yes, I work with IT teams differently than with traditional business. A Cherkasy IT Cluster startup usually needs not a CRM but the SaaS product itself: multi-tenant architecture, billing, roles, customer-facing API. Here I act as a technical partner or CTO-as-a-service: design the architecture on Next.js + Node.js + PostgreSQL, set up CI/CD on AWS or Google Cloud, help hire the first engineering team.
If you are building a B2B SaaS for the Ukrainian or European market, I will share references and explain how to avoid typical MVP-stage mistakes.
Honest range for Cherkasy: a small CRM for a sales department — 8,000 to 15,000 USD; a full ERP with production, warehouse and 1С — 25,000 to 60,000 USD. The exact number appears after a 1-2 week discovery phase, where I map scenarios, roles, integrations and break the project into milestones.
I work either on a fixed price per stage or time & material — we choose together. The contract covers code and documentation handover, so you are never held hostage by the agency. Details on Contacts.
Security is built into the architecture: distinct roles and rights in PostgreSQL, encryption of sensitive fields, audit logs of all user actions, two-factor authentication for admins. Backups run daily with quarterly restore tests. For critical installations I deploy in a private VPC on AWS or Google Cloud.
For businesses handling personal data (retail, healthcare, education) I align the system with GDPR and Ukrainian data-protection law. A separate security review runs before each release.
Yes, this is one of the most common tasks. Leads from a Next.js website, Tilda forms, calls from Binotel or Ringostat, requests from Prom, Rozetka, OLX, messages from Instagram and Facebook — all merge into one CRM funnel. Every lead carries source, UTM tags and the full touch history.
Marketing sees cost per lead by channel, sales sees the full client picture. If you already have a website, I integrate via REST API; if not, we build the bundle together — see Web Development.
No CRM works if the team rejects it. So I always split rollout into waves: start with one department (usually sales), bring it to a working state, then add warehouse, production, finance. For each department — a dedicated onboarding, video instructions in Ukrainian and checklists.
The first month after launch I am personally on call: weekly meetings with key users, quick UX fixes, extra training. This is the most expensive stage for competing agencies and exactly where they collapse — for me it is included in the fixed price.
Your business, your code. The contract covers handover of repositories, infrastructure, documentation and access. I deliberately use an open stack (Next.js, Node.js, PostgreSQL) so any other team can continue without a rewrite.
Every project comes with technical documentation: DB schema, API description, deployment guide, decision log. If needed, I help find the next contractor or in-house developer. See About.
Yes, manufacturing ERP is a separate track. For machinery (similar to Bohdan Motors and smaller Sosnivskyi-district plants) I cover BOMs, routings, work-in-progress, batches and serial numbers. For food processing and the sugar industry — raw material tracking, recipes, shelf life, lots.
Integration with shop-floor equipment is possible via OPC UA, MQTT or file exchange — depending on the equipment park. We start with an MVP on 1-2 production lines and scale from there.
Cherkasy region agribusiness has its own logic: future-harvest contracts, fuel and lubricant prepayments, field monitoring, machinery tracking, export contracts in foreign currency. I build a CRM that respects seasonality: a funnel from sowing to elevator, contracts linked to fields and crops, integration with 1С Agro or BAS Agro.
A dedicated module for export deals comes with multi-currency, Incoterms binding and automatic payment reminders. For many farms this is the first move from Excel to transparent accounting.
Yes, for Cherkasy IT Cluster teams and independent SaaS startups I am a frequent technical partner. I build multi-tenant architectures on Next.js + Node.js + PostgreSQL, with data isolation at schema or row-level. I plug in billing (Stripe, Fondy, LiqPay), roles and permissions, audit log, public API.
For early MVPs I can act as a fractional CTO: architecture, hiring the first developers, code reviews, technical interviews with investors. Your product, your brand; I stay in the shadow if you prefer.
Yes, transparency is the basis of my work. Every project runs in Linear or Jira with open access for the client. Once a week — a Zoom or Google Meet demo where you see the real system, not a PowerPoint deck. Between demos a staging server with the latest build is always available.
Priority changes are part of the job. Few things are fully known at start, so I build a discovery buffer into each sprint. I am happy to work with your project manager or run the project myself. Book a call on Contacts.

Cherkasy is no longer just an industrial city. Alongside the classic giants of chemistry, sugar and machinery, a powerful layer of agribusiness, regional retail and IT teams united in the Cherkasy IT Cluster has emerged. They all grow faster than their internal systems. I am Oleksandr Filyuk, with 15+ years building CRM, ERP and SaaS products and 130+ delivered projects. I help Cherkasy businesses make the leap from Excel and boxed Bitrix24 to their own controlled platforms.
Most often companies come to me where sales lives in one system, production in another, accounting in a third. Data is moved by hand, the owner looks at weekly reports and trusts no number. I close that gap with one connected system on an open stack: Next.js, React, Node.js, PostgreSQL, REST API and GraphQL for integrations. I connect to 1С, BAS, RetailCRM, Bitrix24, Salesforce, Pipedrive, HubSpot — without hard vendor lock-in.
Bitrix24, RetailCRM, amoCRM are good starting tools. While the business is simple they cover 80% of needs. Problems start when a mixed model appears: wholesale agricultural products plus processing plus export plus a retail chain. In boxed systems this becomes an expensive web of workarounds, custom modules and per-user monthly fees. At some point the cost of supporting the box exceeds the cost of custom development.
A custom CRM on Next.js and Node.js gives a clean data model for your real process. Funnels with a production stage, separate price lists for wholesalers and fuel-station chains, multi-currency for export to Poland, Moldova, the EU, flexible roles and permissions. You do not pay per user. You own the code and do not depend on vendor updates that break your customizations.
I do not push custom development on everyone. During discovery I will say honestly: if you have five managers and simple B2B sales, RetailCRM will be cheaper. Custom CRM makes sense from 15-20 users, two or more integrations or non-standard business processes. If your case is different, I will help configure the box correctly and save your budget.
Manufacturing ERP is a separate world. For machinery plants in the Sosnivskyi district (modeled on Bohdan Motors and smaller factories) I cover BOMs, routings, work-in-progress, batches and serial numbers. For food processing, sugar and dairy — raw material tracking, recipes, shelf life, lots, quality control. Shop-floor equipment integration is possible via OPC UA, MQTT or file exchange — depending on the equipment park.
Cherkasy region agribusiness has its own logic: future-harvest contracts, fuel, lubricant and seed prepayments, satellite field monitoring, machinery tracking, export contracts in foreign currency. I build an ERP that respects seasonality: a funnel from sowing to elevator, contracts linked to fields and crops, integration with 1С Agro or BAS Agro. A separate export module with multi-currency, Incoterms and automatic payment reminders.
The start is always the same — a 2-4 week discovery phase. I visit the production site or an office on Soborna Square, talk to department heads, map scenarios in Miro or FigJam. Only after that does the code begin. The first release is an MVP for one production line or one warehouse, then phased expansion.
I work differently with IT teams. A Cherkasy IT Cluster startup needs not a CRM but the SaaS product itself. Here I act as a technical partner or fractional CTO: I design a multi-tenant architecture on Next.js + Node.js + PostgreSQL, with data isolation at schema or row-level. I plug in billing via Stripe, Fondy or LiqPay, roles and permissions, audit log, public API for customers.
I set up CI/CD in GitHub Actions or GitLab CI, deploy on AWS, Google Cloud or Hetzner — depending on budget. For early MVPs I take on the fractional CTO role: architecture, hiring the first developers, code reviews, technical interviews with investors. Your product remains your brand; I stay in the shadow if needed.
A modern CRM does not live in isolation. I integrate systems with a Next.js website, Tilda forms, Binotel or Ringostat telephony, marketplaces Prom, Rozetka, OLX, messengers Instagram, Facebook, Telegram, APIs of Ukrainian banks. For logistics — Nova Poshta, Ukrposhta. For marketing — Google Ads, Facebook Ads, email services.
Security is built into the architecture: roles and permissions in PostgreSQL, encryption of sensitive fields, audit logs, two-factor authentication. Backups daily, with a quarterly restore test. For businesses with personal data — GDPR and Ukrainian law compliance. A security review before each release.
Step one is a free 30-minute call where I listen to your task and honestly say whether it is my case. If yes — a 1-2 week discovery phase at a fixed price. You receive scenario maps, a DB schema, mockups of key screens, a roadmap and an honest budget estimate. Then phased development with weekly demos. The first month after launch is my direct support with an SLA on critical bugs. Book a call: Contacts. More about me — About.
