I build AI automation systems that help businesses respond to leads faster, update CRMs automatically, reduce manual work, and connect the tools they already use.
If your team is dealing with slow follow-up, disconnected apps, messy spreadsheets, manual copy-paste work, or repetitive client communication, I can help turn that into a clean automated workflow.
My focus is not just “building a bot” or “connecting two apps.”
I build practical business systems that save time, reduce errors, and make daily operations easier to manage.
What I can help you automate:
→ Lead capture and follow-up
Automatically collect leads from forms, websites, ads, WhatsApp, Telegram, email, or spreadsheets — then route them into your CRM, notify your team, and trigger the right follow-up.
→ CRM and pipeline workflows
Automate lead creation, status updates, task creation, tagging, reminders, notifications, and handoffs between sales, operations, and support teams.
→ AI chatbots and assistants
Build AI-powered bots for WhatsApp, Telegram, and websites that can answer questions, qualify leads, collect information, send links, update records, and escalate to a human when needed.
→ Internal business automations
Replace repetitive manual work across Google Sheets, Gmail, Google Drive, Airtable, ClickUp, Notion, Slack, CRMs, and other business tools.
→ AI workflow systems
Use OpenAI, Claude, and structured prompts to summarize messages, classify requests, generate replies, score leads, extract data, draft outreach, and make workflows smarter.
→ API integrations and custom backend logic
When no-code tools are not enough, I can build custom API logic, FastAPI backends, webhook handlers, and database-connected automation flows.
Recent systems I’ve built:
→ WhatsApp AI chatbot connected to CRM and payment status logic
→ Jotform → Make → ClickUp automation for product operations
→ AI outreach research pipeline using Apify, Airtable, Make, and OpenAI
→ Telegram bot with FastAPI backend and Google Sheets integration
→ Automated lead capture and instant follow-up systems
→ Google Workspace workflows for Sheets, Gmail, and Drive
→ CRM automation with tagging, status updates, and task creation
Tools I work with:
n8n · Make · Zapier · OpenAI · Claude · Python · FastAPI · Supabase · Airtable · Google Sheets · Gmail · Google Drive · ClickUp · Notion · WhatsApp Business API · Telegram Bot API · Webhooks · REST APIs
How I usually work:
1. I first understand your current workflow and where time is being wasted.
2. I map the automation logic clearly before building.
3. I build the system using the right mix of no-code, low-code, AI, and custom code.
4. I test the workflow with real examples and edge cases.
5. I document the system so you are not left with a black box.
I prefer clean, reliable systems over fragile “quick hacks.”
My goal is to build automations that your business can actually use every day, not just impressive demos that break later.
Good fit if you need:
→ A chatbot that actually connects to your business process
→ A lead pipeline that responds faster than your team can manually
→ A CRM workflow that updates itself
→ A Make, n8n, or Zapier automation built properly
→ AI added into an existing workflow
→ A custom automation where standard tools are not enough
→ Someone who can think through the business logic, not just connect modules
I work milestone-based, communicate clearly, and keep the system understandable from start to finish.
Send me your current workflow, the tools you use, and what you want to automate - I’ll help you find the fastest and cleanest way to build it.

Senior Python backend developer with 10+ years building scalable SaaS platforms, REST APIs, and AI-powered systems in Python, Django, DRF, and FastAPI. I turn product requirements into clean architecture, reliable integrations, and production-ready delivery.
Need someone to own the backend — from database and API design to LLM integrations and deployment? That's my core strength. I focus on backend-heavy web applications where reliability, maintainability, and business logic matter most, and I help teams fix slow, messy, or hard-to-maintain Python/Django codebases by restructuring logic, stabilizing APIs, and cutting technical debt.
I also deliver end-to-end SaaS MVPs — integrations, admin flows, auth, deployment, and collaboration across the full web stack.
𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱:
🟢 SaaS backends and MVPs (Django / DRF, FastAPI)
🟢 REST APIs, webhooks, and third-party integrations
🟢 AI & LLM features — OpenAI, Claude, LangChain, LangGraph, RAG
🟢 Workflow automation and ETL pipelines (Celery, Redis)
🟢 Admin panels, authentication, roles & permissions
🟢 Refactoring & scaling legacy Python / Django systems
🟢 Docker-based deployment, AWS, and CI/CD
𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗵𝗶𝗿𝗲 𝗺𝗲 𝘁𝗼:
🟢 Launch the backend for a new SaaS product
🟢 Stabilize and scale an existing Django application
🟢 Build APIs and integrations that scale reliably
🟢 Automate manual business workflows
🟢 Add AI / LLM functionality to an existing platform
🟢 Get senior-level execution without unnecessary complexity
𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲:
Over 10+ years I've shipped products across SaaS, fintech, healthcare, education, and internal business tools. I build modular, well-structured systems that stay easy to extend as your product grows — especially strong in API-heavy platforms, async workflows, and third-party integrations.
𝗖𝗼𝗿𝗲 𝘀𝘁𝗮𝗰𝗸:
Python · Django · Django REST Framework (DRF) · FastAPI · PostgreSQL · MySQL · Celery · Redis · Docker · AWS · GitLab CI/CD · REST APIs · Webhooks · Stripe · Twilio · OpenAI · Claude · LangChain · LangGraph · React
𝗛𝗼𝘄 𝘄𝗲 𝘀𝘁𝗮𝗿𝘁:
For projects where the scope needs validation, I offer a paid discovery phase — a practical way to align on architecture, priorities, and a delivery plan before a larger engagement. You leave with a clear roadmap, fixed next steps, and no guesswork.
If you need a solid Python/Django backend, clean APIs, AI integrations, and senior-level execution with clear communication, send me a message — I'll reply with honest feedback on your project.

Can't figure how to launch up your SaaS MVP?
I help startups/solopenuers & enterprises build AI-powered apps that cut costs, boost revenue, and scale fast.
Hi, I’m a Top Rated Plus Full-Stack AI Engineer focused on AI product engineering + agentic systems/pipelines & orchestration. I build end-to-end solutions, from UX to backend to infra, that ship fast, scale cleanly, and actually work in production (not just demos).
If you’re building an AI-powered MVP, internal tool, or customer-facing SaaS, I can help you go from idea → architecture → build → deploy → iterate with a strong emphasis on reliability, security, and measurable outcomes.
🚀 What I build (AI & Custom Software Development):
1) RAG / Knowledge Base Chatbots (docs, Notion/Drive, internal wikis) with citations + guardrails
2) LLM features inside products (summaries, extraction, classification, agents, tool-calling)
3) AI dashboards (analytics, ops panels, admin tools) + role-based access
4) Production-ready backend systems (auth, billing hooks, queues, caching, rate limits,payments systems)
Real-world impact from some of my solutions:
1) TerraPrime - AI real estate opportunity matching platform: Built and scaled the platform to 15K+ paying users, involving investors & developers, across the world & accelerating to date.
2) Mindcrate - Document generation and AI drafting system: Built a document-extraction and drafting system with Payments, Authentication & Infra that has driven $700K+ revenue.
3) StudioIQ Pro - Agentic large-scale OS for Post-Production/VFX industries, serving clients like Netflix/HBO, crossing $950K+ ARR.
🔧 Tech Expertise:
- Python | TypeScript | React | Next.js
- Redux | SSR | React Query | PWA | Tailwind | MUI | Shadcn | Chakra UI
- Product-quality UI, performance, and SEO foundations
- Node.js | NestJS | FastAPI | Django
- API Design | Integrations | Secure Auth (JWT, OAuth, OTP)
- Background jobs, queues, webhooks, event-driven workflows
- RAG pipelines | embeddings | vector search (based on your stack)
- LangChain | LLM orchestration | evaluation + prompt/versioning patterns
- Reliability guardrails (validation, fallback flows, logging/traceability)
- PostgreSQL | MySQL | MongoDB | Supabase | Firebase | GraphQL
- Redis / caching patterns (when needed)
- AWS (S3, EC2, Route53, Lambda) | Docker | GitHub Actions | CI/CD | CloudFront CDN
✅ WHEN I AM THE BEST FIT FOR YOU:
- You are serious about your product, want it to succeed & want to see working product from week 1.
- You want some that can leverage power of AI Coding and Enterprise sofware engineering techniques to maximum, with a realistic balance.
- You have a realistic budget that reflects the value of quality craftsmanship and clean, maintainable delivery, over AI generated crap that has lots of security issues and fails in production.
- You appreciate a structured approach: one that prioritizes careful planning, sound architecture, and deliberate decision-making over hasty execution, so that once product is launched it succeeds.
- You require a solution built for real-world production environments, not a prototype that falls apart under pressure.
- You value consistent communication, transparent progress updates, and a collaborative working relationship.
❌ I AM NOT THE BEST FIT IF:
- Your primary selection criterion is the lowest possible rate, regardless of outcome quality.
- You expect a fully realized, complex build delivered within an unrealistic or arbitrarily compressed timeline, thinking that AI can magically do everything.
- You intend to proceed without a clearly defined scope, necessary access, or documented requirements.
- You prefer a hands-off arrangement with little room for professional input, recommendations, or strategic discussion.
- You are willing to compromise long-term stability, scalability, and reliability in exchange for speed.
✅ Let’s Collaborate
I combine founder-speed execution with enterprise-level engineering discipline. If you want an AI product that’s dependable (and not “hallucination-prone”), or an automation system that won’t break every week, I’m your person.
📩 Message me with your idea + what “success” looks like, and I’ll reply with a mini plan + roadmap (phases, risks, and the fastest path to value).

Most SaaS products do not need another redesign. They need a developer who can improve performance, stabilize the platform, fix scaling issues and build features properly without breaking existing workflows.
I mainly work on Laravel and React based SaaS applications that are already being used by real businesses and now need stronger architecture, faster dashboards, cleaner APIs, subscription systems, workflow automation or long-term product development.
A lot of clients reach out when:
• The SaaS platform becomes slow as users grow • APIs start failing or become difficult to maintain • The dashboard feels messy or unstable • Subscription and billing logic breaks • Developers left behind unstructured code • Features were added quickly and now create conflicts • The backend becomes difficult to scale • Frontend performance starts affecting user experience

🔥I help startups and growing businesses build fast, scalable web and mobile apps using Python, Laravel, React Native, and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥
🚀I also lead a web development team, Join.To.IT from Kyiv, Ukraine as co-founder and CEO. We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀
I’m an experienced Laravel engineer, React engineer, Vue engineer, and React Native engineer with 14 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements.
My skills:

API Integration
Stack of technologies we use:
✅ HTML/CSS, Bootstrap, Tailwind
✅ JavaScript (React, Vue, Node.js, Express, AdonisJS, Nuxt)
✅ React Native for cross-platform mobile delivery
✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more)
✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL)
✅ PWA (Progressive Web App)
✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch
✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase
✅ DevOps and administration: LAMP, CentOS, Ubuntu
As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable.
You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work.
Our team has already worked in such industries as:
✅ Marketplace
✅ E-commerce
✅ Travel and Hospitality
✅ Custom ERP (Enterprise Resource Planning)
✅ ChatGPT integration (LLM model in your website front end)
✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling)
✅ Social media (Tinder-like networks, short video platforms, communities)
✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments)
✅ Sport (gym management systems, trainer platforms, fitness apps, club portals)
✅ Legal (document automation, AI-assisted legal processing)
✅ Healthcare (clinic management, booking, mental health software)
✅ Education (LMS, automated training, coaching marketplaces)
✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators)
✅ Manufacturing (shop floor management and automation)
✅ Human resources (HRM systems)
✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics)
In our work history you’ll find successful products built with Laravel, PHP, JavaScript, MySQL, React, Vue, WordPress development, Web Development, Full Stack development and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience.
We have 65 senior developers across PHP, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations.
Don't hesitate to get in touch with me for further details and fruitful work.
