Project details
You will get a production-ready full-stack web app: React/Next.js on the front, Node.js/TypeScript behind it, PostgreSQL or MongoDB for data. Built for real use - auth, roles where needed, clean architecture, and full code ownership.
I start from scratch or extend an existing codebase. Every order begins with a short discovery so the scope matches the tier you buy.
What’s included (tier-dependent):
• Frontend + backend in one delivery
• REST API and database schema
• Auth / role access
• Responsive UI for core screens
• Third-party API integrations
• Deploy + logging
• Source code, short documentation, handoff
Best for SaaS MVPs, admin panels, internal tools, client portals, and finishing half-built products.

Backend Developer Node.js Needed for Existing Web Platform
Aleksei jumped into our existing codebase and started delivering immediately. Worked across Node.js, Python, and Java like he'd been on the project for months. Clean code, no hand-holding, got things done. Would happily work with him again.

Telegram Bot for AI Assistant - Human Handoff & Multi-Trainer Ready
Loved working with Aleksei! He built us a Telegram Bot that connects our AI to trainers - routine replies through the AI, tricky ones to a human. Multi-tenant from day one, clean work, on time. Would happily work with him again. 👍

Job Success
Belgrade, Serbia - 8:27 pm local time
Founder of a development studio in Belgrade with an in-house team. 12 years in IT consulting and business analysis - I think like a product owner, not just a coder. Every project starts with discovery: I find what actually eats your team's time, then build the system that replaces it. On time, on budget, with a 6-month warranty and full code ownership transferred to you.
WHAT I BUILD
FULL-STACK WEB APPS AND DASHBOARDS
React and Next.js on the front; Node.js on the back; TypeScript across the stack. PostgreSQL or MongoDB for data. SaaS platforms, admin panels, internal tools, client portals. Connecting existing interfaces to live APIs, finishing half-built products, and extending inherited codebases - I am comfortable taking over someone else's project.
AI INTEGRATION
OpenAI and Claude APIs added into real business workflows - structured outputs. AI agents with confidence thresholds, human handoff and anti-hallucination guardrails. RAG systems with custom chunking, embeddings and citation-grounded answers.
Live example: a RAG assistant on my cases, background, and how I work - search @NekaSoftBot on Telegram.
BACKEND AND APIs
Backend with REST APIs, webhooks, background jobs and database design. I build payment integrations (Stripe, PayPal, PayAnyWay) with safe payment handling. My backends can be multi-client setups, using OAuth, third-party integrations and error logging. Usual stack: Node.js/TypeScript, Koa, PostgreSQL or MongoDB, Keycloak for auth
AUTOMATION AND DATA PIPELINES
Web scraping and ETL with Playwright and Selenium. Scheduled extraction, data validation, structured export to Excel and Google Sheets, automated reporting. Real pipelines with error handling and logging - not one-off scripts. Report automation saved a manufacturer 10+ hours per week; lead intake automation freed 20 hours per month.
TELEGRAM BOTS AND MESSAGING AUTOMATION
Production bots serving 1,500+ users: helpdesk ticketing with two-way sync, subscription and payment flows, CRM verification, lead capture with analytics. TypeScript, Telegram Bot API, grammY.
DEPLOYMENT
Deployment on VPS or Railway - with monitoring, logging, and documentation. I can use your VPS or help choose a provider. Stack: Docker, Nginx, CI/CD with GitHub Actions.
HOW I WORK
- Discovery first: I map the process and understand your business goal before writing code, so the scope is real and the estimate holds.
- I lead every project personally - from requirements through architecture, development, QA and release.
- Clear communication: progress you can see, questions asked early, no silent weeks.
- Clean handover: documented code, deployment instructions, full ownership transferred.
As a result: 100% Job Success and clients who come back with new projects - that is how I measure quality.
Tech: Node.js, TypeScript, JavaScript, React, Next.js, PostgreSQL, MongoDB, Supabase, Docker, CI/CD, REST APIs, webhooks, OpenAI API, Claude API, RAG, pgvector, Playwright, Selenium, Google Sheets API, Stripe, Telegram Bot API.
Tell me what is eating your team's time, or what is half-built and stuck - I will tell you honestly whether I am the right fit and what it takes to finish it.
