I'm the Founder & CEO of two AI companies - UppLabs (Top 1% AI development agency on Clutch & Upwork) and OpsWorks Co. (DevOps and Cloud consultancy, AWS, GCP amd Azure Partner) - with a combined team of 50+ certified engineers.
BY THE NUMBERS:
🏆 100+ AI, DevOps, and software projects delivered
🏆 $2M+ combined earned on Upwork, 100% Job Success Score
🏆 $100M+ in client revenue generated
🏆 100+ certifications across the team
🏆 60,000+ hours logged, 200+ completed contracts
TWO THINGS WE DO BETTER THAN ALMOST ANYONE ON UPWORK:
🤖 1. BUILD AI-POWERED SOFTWARE
Custom AI agents, RAG pipelines, production ML models, and full-stack platforms for Fintech, Healthcare, and PropTech. Not ChatGPT wrappers - real systems that process transactions, automate clinical workflows, and make business decisions. Clients include Deloitte, Citibank, Disney, and TimelyCare.
⚙️ 2. BUILD INFRASTRUCTURE THAT RUNS ITSELF
AI-augmented DevOps, AWS/GCP/Azure architecture, and intelligent monitoring that self-heals, auto-scales, and cuts cloud costs. ETX Capital cut infrastructure spend by 50%. Syndigo cut costs by 92%. Vodafone improved efficiency by 40%.
HOW WE WORK - AI-NATIVE FROM DAY ONE:
We don't just build AI products - we use AI agents and modern automation internally to deliver faster and better than traditional teams.
🛠️ On the development side:
- AI-assisted architecture design and code generation to ship features 3x faster
- Agentic code review pipelines that catch bugs and security issues before humans do
- LLM-powered test generation and documentation — zero manual overhead
- AI pair programming across the entire engineering team as standard practice
🔁 On the DevOps side:
- AI agents that monitor infrastructure 24/7, detect anomalies, and self-heal before incidents occur
- Intelligent CI/CD pipelines with LLM-powered deployment gating and rollback triggers
- Agentic cost optimization that continuously rightsizes resources and eliminates waste
- AI-driven incident response that diagnoses, escalates, and resolves issues autonomously
💡 The result: your product gets built faster, your infrastructure costs less, and your team spends zero time on problems that machines can handle.
WHAT YOU GET:
✅ Production-ready AI: agents, LLM pipelines, fraud detection, clinical AI, compliance automation
✅ AI-native web and mobile apps built to scale (React, Next.js, React Native)
✅ Zero-downtime infrastructure on AWS, Azure, GCP with Kubernetes and Terraform
✅ Full compliance: HIPAA, SOC2, PCI DSS, ISO 27001, GDPR, OWASP
✅ Cloud cost reduction of up to 90% using AI-driven optimization
✅ MVPs shipped in weeks, not months - 3x faster time-to-market
Whether you need an intelligent product built from scratch or infrastructure that stops costing you sleep - let's talk. 🚀

I help teams turn scattered docs, tickets, and logs into LLM‑powered internal tools and automation that save hours per week and reduce operational mistakes.
Over the last 9+ years I’ve built and operated secure, production‑grade backends, AI features, and DevOps pipelines for SaaS products, higher‑education, and enterprises.
What I can do for you
✅ Build "Chat with your Data" & RAG Systems
• Internal "ask anything" assistants over knowledge bases, handbooks, logs, tickets
• RAG pipelines with robust retrieval, access control, and evaluations
• OpenAI & Claude integrations (chat, embeddings, tools/agents), including Azure OpenAI
• Modern dev tooling: Cursor, Claude Artifacts, MCP servers for reliable tool‑use
✅ Design & Implement Reliable Backends
• Python APIs and microservices (FastAPI / Django REST / Flask) behind your AI features
• Clean, testable architecture and documentation your team can maintain
• SQL/NoSQL data models, caching (Redis), background jobs, webhooks
✅ Automate Workflows & Operations
• AI‑driven workflows that reduce manual review and ticket triage
• Integrations between your app and third‑party tools (CRMs, email, marketing, data platforms)
• Scheduled jobs, alerting, and reporting dashboards
✅ DevOps & Cloud Infrastructure
• Docker & Kubernetes deployments, CI/CD pipelines
• Infrastructure as Code, observability (logging, metrics, tracing)
• Secure, scalable setups on AWS/Azure (networking, secrets, backups)
🏆Why clients hired me
✅Business‑first, not model‑first. Every AI feature and backend change is tied to a clear goal: faster workflows, fewer errors, or better insight from your data.
✅Production mindset. I focus on reliability, observability, and security from day one, so your system can stand up to real usage, not just demos.
✅Clear communication. I keep you updated with short, non‑technical status summaries and propose options with trade‑offs so you can decide quickly.
✅End‑to‑end ownership. From initial architecture and POCs through deployment, monitoring, and hand‑over documentation.
🧑💻Next steps
If you need an engineer to design, build, or stabilize AI‑driven backends, RAG apps, or internal automation, send me a short message about:
1. What your system does today?
2. what you want it to do and what do you want to build?
3. ETA
I’ll reply with an honest assessment of fit and a concrete next step (quick call, architecture sketch, or small paid discovery task).
