Hi! I'm a full-stack developer who ended up specializing in a weirdly specific niche: taking things that almost work – a rough AI idea, a half-finished MVP, someone's vibe-coded weekend project – and turning them into something a real business can actually run on.
I take on projects at any stage – from a blank page and an idea, to an existing codebase that needs new hands on it.
I've been building software professionally for years, and the work that gets me genuinely excited right now is at the intersection of AI and practical business systems: agents that quietly take hours of manual work off someone's plate, dashboards that finally show a founder what's actually happening in their business, and MVPs that go from "idea on a whiteboard" to "thing customers are using" faster than most teams think is possible.
☑️A bit about how I got here
I started out doing classic full-stack work – websites, web apps, the usual. Somewhere along the way I noticed a pattern: the most interesting projects weren't "build me a website," they were "we have this process that's eating 10 hours a week, can you make it disappear" or "we tried to build this ourselves with AI tools and it's held together with tape, can you fix it." That's where I've stayed ever since.
☑️What I actually do
→ AI agents & automation – I build agents that handle real work: customer support triage, report generation, data entry, internal admin. Not chatbot demos – things that replace hours of someone's week, every week.
→ Custom business systems – CRMs, internal dashboards, workflow tools built around how your team actually works, not around a template you have to bend your process to fit.
→ SaaS MVPs – if you have an idea and need to see it as a real, clickable product fast, this is probably my favorite type of project. Weeks, not months.
→ Rescuing stuck projects – this might be the thing I'm most known for at this point. Half-finished builds, AI-generated ("vibe-coded") apps that worked in a demo and fell apart with real users, code from a developer who disappeared mid-project. I go in, figure out what's actually salvageable, and get it to a stable, shippable state – almost always without needing a full rebuild.
→ Web & mobile development – still very much in my toolkit when that's what the project actually needs.
☑️How I work
I don't start typing code the moment a job is posted. I ask questions first – sometimes annoyingly many of them – because building the wrong thing fast is worse than spending an extra hour making sure we're building the right thing.
Once we're aligned, I move quickly, communicate proactively (you'll hear from me before you have to ask "any update?"), and I'm honest early if something in the original plan doesn't make sense anymore.
If you're not sure exactly what you need – just a business problem and no spec – that's a completely normal place to start a conversation with me from.
☑️A few results from recent projects
·Rebuilt a client's internal CRM around their actual workflow → 35% increase in operational capacity
·Automated order syncing for a manufacturing client → 8–12 hours saved per week
·Took over a 500-page Figma design that needed real engineering behind it → delivered a working, production-ready MVP on schedule
·Picked up a stalled, partially AI-generated MVP that broke under real traffic → stabilized it into a product the client could confidently launch
☑️When it makes sense to reach out
· You have a manual process eating your team's time and suspect AI could kill it
· You need a CRM, dashboard, or internal tool that fits your actual workflow, not a generic template
· You started building something yourself (with AI tools or otherwise) and it's not quite production-ready
· You have an idea and want to see a real MVP fast, not a six-month roadmap
· You just want a second opinion before committing budget to a build – happy to do a quick, honest audit first
Send me a message with what you're working on. Even if it's half-formed, that's a fine place to start.

Hello! 👋 I’m a Senior Full‑Stack Engineer who helps founders and teams ship product features without drama.
My focus is business outcomes first: clear scope, predictable delivery, maintainable code, and a UI that feels polished and trustworthy. I’m comfortable owning a feature end-to-end – from discovery and UX decisions to backend architecture, deployment, and monitoring.
I’m also UI/UX-minded: I can prototype flows in Figma, define a simple design system (tokens/components), and ship it as clean, accessible UI. For design-only tasks, check my UI/UX specialized profile.
What I can help you with
::: SaaS and internal tools: dashboards, admin panels, role/permission systems
::: Headless CMS builds: Strapi / Payload CMS, content modeling, roles, custom APIs, SEO workflows
::: Cross-platform: Tauri/Dioxus, Flutter – desktop/mobile + native integrations
::: Web3: on/off-chain architecture – wallets, indexers, token/NFT tooling, dApp, backend integrations
::: AI features: OpenAI tool-calling, RAG pipelines, evaluation, cost/performance tuning
::: Backend & real‑time: REST/GraphQL, WebSockets, background jobs, queues, caching
::: Bots & integrations: Telegram + Discord, webhooks, payments, third‑party APIs
::: Hardening: performance, security basics, stability, observability, production support
How I work
::: Align on goals and constraints → define measurable success (speed, conversion, reliability, cost)
::: Provide a delivery plan → milestones, risks, tradeoffs
::: Ship iteratively → short feedback loops, demos, transparent progress
::: Stabilize → edge cases, testing where it matters, monitoring and docs
Tech snapshot
::: Frontend: Vue / React, Nuxt / Next.js, Astro, TypeScript, component systems, design tokens, Tailwind
::: Backend: Rust, Go, Node/Bun/Deno – APIs, real-time, background jobs
::: Data: PostgreSQL, Redis, SQL performance and indexing
::: CMS: Strapi, Payload CMS
::: Cross-platform: Tauri/Dioxus, Flutter
::: Web3: Solana, wallets, on-chain data, indexers, dApp integrations
::: Delivery: Docker, Kubernetes, CI/CD (GitHub Actions), Nginx/Traefik, logging/metrics
::: AI: OpenAI API integrations, RAG, evaluation, cost/perf tuning
If you want someone who communicates clearly, thinks in outcomes, and can own delivery from UI to production – message me with your goal and any constraints, and I’ll propose the cleanest path to ship.

LLM and GPT Integrations
Production-grade ChatGPT integration with cost optimization, error handling, and fallback strategies. I've helped clients reduce OpenAI API costs by 60-70% while maintaining or improving output quality.
API Integration with Business Systems
I connect AI agents to CRMs, ERPs, and workforce tools. Experience with Bitrix24, HubSpot, When I Work, and custom API integration with existing backends including Laravel and other frameworks.
RAG Systems
Knowledge bases that actually return accurate answers. Vector databases (Pinecone, Weaviate, FAISS), chunking strategies, retrieval tuning, and evaluation pipelines.

I build production AI systems — and the data pipelines that feed them.
Most AI projects stall at the same wall: the team wants an agent or RAG system, but the underlying data lives in scattered PDFs, broken APIs, half-scraped websites, and legacy databases. I do both halves of that problem, which means your AI build doesn't pause for three months while someone "figures out the data."
Top Rated Plus, 100% Job Success, 2,000+ hours delivered across real estate, finance, e-commerce, healthcare.
Recent AI work
— AI assistant for an electronic-components distributor: live BOM cross-referencing on real ArduPilot / Pixhawk hardware, 84% catalog coverage in a recorded client demo.
— AI ops assistant for CPA / affiliate networks: native integrations with Affise, Keitaro, Voluum, and Tune. LLM-driven offer-matching.
— RAG over technical PDFs (datasheets, schemas, contracts) with sub-second retrieval and Claude / GPT-4 as the answer layer.
Recent data infrastructure work
— 200K+ legacy financial documents migrated to PostgreSQL with custom schema and full data lineage.
— Real Estate Data Lake with daily refresh across 12 source platforms.
— Large-scale scrapers for Amazon, Etsy, and niche marketplaces with anti-bot rotation and clean dataset output.
How I work
Week 1 we lock scope and edge cases. Week 2–3 you get something working — not slides. After that we iterate against real data, not assumptions. I treat AI agents as engineering, not prompts: evals, guardrails, error budgets, observability. No "let's hope the model behaves."

AI: Python / FastAPI, LangChain, LlamaIndex, OpenAI / Anthropic / DeepSeek, Pinecone / Qdrant / Chroma, Postgres + pgvector.
Data: Playwright, Scrapy, Selenium, Polars, Pandas, Airflow, AWS / GCP.
If your project needs both — or you're not sure where data ends and AI begins — send me what you're trying to build. I'll reply within 24 hours on whether I'm the right fit.
