    ⭐Top-rated DevOps expert with 70+ completed projects on Upwork. I lead a team of highly motivated DevOps experts who help SaaS businesses to build scalable, high available and secure infrastructures on AWS/GCP/Azure according to the best practices. What you will get with me and my team? ✅Price & Value balance. With us, you get top-quality DevOps assistance at a reasonable price. We are sensitive to customer’s needs and use a proactive mindset and efficient workflow to exceed your expectations. ✅Long-term support. We tend to build reliable long-term relationship with our customers, supporting them throughout their product lifecycle. ✅Relevant expertise. Our team members use all modern DevOps tools & technologies to cover various challenges. We have AWS/GCP certified experts in team and internal DevOps training program which helps to grow strong talents in-house. ✅Business-oriented approach. We work with startups and businesses of different scale every day and know how to enable the efficient use of resources and save up to 80% in your infrastructure costs, how to improve deployment time from weeks to minutes, and how to make your setup secure. ===== Technologies that I adopt and I’m an expert at: - AWS, GCP, Azure - Docker - Kubernetes - Terraform - Ansible - Jenkins, CircleCI, GitHub/BitBucket pipelines - Prometheus - Grafana - Datadog etc. My area of expertise includes: DevOPS • CI/CD • Infrastructure as Code • Container Orchestration • Configuration Management SysOPS • Remote Infrastructure Management Services • Monitoring • Application Management • Infrastructure Upgrades/Migration CloudOPS • Cloud Administration (AWS, GCP, Azure, Digital Ocean) • Cloud Monitoring & Maintenance • Cloud Cost Optimization • Architecture Consulting • Cloud migration DbOPS • Remote Database Administration Services • Performance Optimization • Orchestrated Migration across platforms/ databases Industries I have experience with: - Fintech - Healthcare - Security - Marketing - Blockchain - Delivery, etc. ===== Case studies of the customers I have worked with: 🔸Safe and Cost-Effective Infrastructure to Bring One-Click Deployment For a Cyber-Security Provider: Deployment time decreased from 8 hours to 10 minutes (48x faster deployment). Fewer resources (time/costs/employee-hours) are now required as code deployment has moved from a tedious, manual process to a codified, automated mechanism. 🔸Backend Infrastructure Design & Development for all-in-one connectivity platform for restaurants & stores: Product provisioning time shortened from 1,5 weeks to 1 hour. Company can drive much more value to their customers now, due to being able to provision the product 200-300 times a month, instead of 5-6 monthly deployments. System redesign and automation allowed to save 30-35% of the budget and free the internal resources for more important tasks. ===== Feel free to contact me or book a consultation, I’d love to discuss your project and help you reach business goals.

    I am an expert level data scientist. I have a certifications for specialisation in Deep Learning( covering image and text data analysis algorithms) I am a "Kaggle competitions expert" with a current rank of 3196 and highest rank of 1727 among 154000 data scientists based on my competition results so far. I also have experience as a full stack engineer having single handedly developed the entire tech stack for the startups where I have been a co-founder in technology. I have used angular as the mvc framework for the frontend, python-flask/java as backend, SQL/ mongodb / elasticsearch as database and also Google Cloud Storage as backend static data storage service. I also have experience in combining the above mentioned skills in creating a semantic search engine (applied to Indian Supreme Court cases). A semantic search engine relies on the meaning of the search phrase rather than try to look up matching keywords to return results. I have completed my B.Tech. from IIT Kharagpur in 2012 and since then have worked on many software projects. At first I worked as a software engineer at 247.ai Since then I have had a taste for both website development and AI and acquired a taste for entrepreneurship. Taking on complete responsibility as a CTO and putting to use my skills as a full stack developer and AI engineer. I am available for both web development and AI based projects on a contract basis currently.
