Services
Engineering services built around real business needs
You pick the solution — we handle delivery. Fixed timelines, transparent pricing, measurable results.
Custom Web Development
Websites that don't just look good — they convert. Landing pages, corporate sites, and online stores with responsive design, technical SEO, and fast load times out of the box.
Responsive layout and mobile-first UX
Mobile-first typography, tap-friendly controls, and consistent rendering from phones to large desktops. We test critical journeys—forms, cart, navigation—so users never get stuck on small screens.
Performance, Core Web Vitals, and conversion
We tune images, code splitting, caching, and network behavior so pages feel fast even on slow connections. Strong LCP, INP, and CLS scores support SEO and reduce drop-off on key funnel steps.
SEO structure, metadata, and search-ready content
Titles, descriptions, canonical URLs, sitemaps, and schema.org tailored to your page types—company, products, articles. Semantic markup and internal linking help search engines understand the site within weeks of launch.
Payments, CRM, analytics, and APIs
We wire up LiqPay, Stripe, WayForPay, or other providers, push leads into CRM, and stream events to Google Analytics / GA4. Optional REST or backend integrations—one data loop instead of scattered spreadsheets.

Telegram Bot Development
Your Telegram bot works like a 24/7 sales manager — taking orders, answering FAQs, sending reminders, and selling while you sleep.
Orders & leads on autopilot
The bot takes orders and requests around the clock: collects contacts, clarifies details, tracks statuses, and sends reminders for payment, delivery, or appointments. Managers step in only for edge cases, so chats stay organized and you avoid mistakes from copying data by hand.
Instant answers, zero queues
Routine questions are answered in seconds—pricing, terms, hours, how to order. Flows can be updated without redeploying the bot, and when a human is needed the handoff includes context so clients don't repeat themselves and you never lose the thread.
Personalization & client history
Each Telegram user gets a stable profile: order history, preferences, segments for campaigns, and tailored offers. That drives repeat business and long-term relationships instead of one-off chat replies.
Interfaces everyone understands
Clients get clear buttons, inline menus, and step-by-step flows without confusion. Your team gets an admin panel or integrated tools to edit copy, review requests, run basic reports, and manage content without calling developers every day.
Data Scraping & Web Parsing
We extract competitor prices, leads, products, and content from thousands of pages. Structured delivery in Excel, JSON, or Google Sheets — ready for your stack.
Static sites, SPAs, and complex flows
We adapt to each source: plain HTML, SPAs with client-rendered content, pagination, filters, and limited authenticated areas—within agreed rules and site policies. We define selectors, handle layout drift, and return data in the shape your team expects.
Cleaning, deduping, and quality checks
We strip noise, normalize dates and numbers, merge duplicates, and drop obvious junk. You get a stable table or JSON you can plug straight into analytics or a CRM—no weekend cleanup sessions.
Delivery to CRM, DBs, and files
Exports to PostgreSQL, MongoDB, Google Sheets, Excel, CSV, or REST endpoints that match your ops. Mix channels—for example daily DB updates plus a weekly sheet for stakeholders.
Schedules, change detection, alerts
Cron or event-driven runs, retries on transient failures, and error logging. Alerts when prices shift, items disappear, or a threshold breaks—so market changes don't slip past your team.

✦ PDF & OCR
PDF OCR & Document Processing
We turn scans, photos, and PDFs into clean, structured data: invoices, waybills, forms, and tables processed automatically — with no manual entry.
OCR for scans, photos, and multi-page PDFs
We handle skewed scans, uneven lighting, and mixed languages in one file. We pick an engine for your case—on-prem or cloud—to balance accuracy, cost, and confidentiality requirements.
Structured fields: tables, totals, legal details
We pull line items from invoices and waybills, tie rows to subtotals and VAT, and capture counterparty details. Output is Excel or JSON with a predictable schema for accounting, ERP, or your pipeline.
Batch jobs for thousands of files
Job queues, per-folder progress, automatic document-type classification, and consistent output naming. Ideal for archives, monthly partner drops, or digitizing legacy scans.
Integrations and hands-off automation
Webhooks when files land in storage, REST APIs for your backend, pushes to CRM or Google Drive. New files follow the same recognition path—no manual copying between folders.
Bulk B2B Contact Collection
We extract emails, phones, and social profiles from thousands of websites in hours. Clean, validated, deduplicated data — ready to import into CRM or cold outreach.
Scale: tens of thousands of sites on a tight timeline
Parallel crawling over URL lists, proxy rotation, and per-domain rate limits for steady, predictable throughput. Suited to large company lists, niches, or regions—you get progress reporting and a summary of access errors.
Full contact and social footprint
Emails, internationally formatted phones, LinkedIn, Facebook, Instagram, Telegram, X/Twitter, support pages, contact forms, and other fields from typical “Contact” blocks. We align rules with you: which source wins when several contacts exist per site.
Validation, deduplication, normalization
Email syntax checks, phone normalization, merges by domain or company, and filtering of generic addresses like noreply. Optional filters by country, page language, or required fields—lists stay outreach-ready for sales.
Exports built for CRM import and automation
Excel, CSV, Google Sheets, or JSON with clear columns and consistent field names. We include source URL and scrape date for audit trails. Import templates for HubSpot, Pipedrive, Zoho, or your internal stack on request.
