Hi,

I'm Vikesh, a software developer, founder, and open source contributor with extensive experience building modern backend, AI, and infrastructure systems. My core stack includes Go, Python, Node.js, and React, with deep work in AI engineering: RAG pipelines, evals, guardrails, agentic automation, and LLM integrations using OpenAI and Anthropic APIs, LangChain, and vector databases like Pinecone and pgvector. I specialize in cloud and DevOps and have worked extensively with AWS, including ECS, Lambda, CloudFormation, ELB, and SES, alongside DigitalOcean, Grafana, and Ansible.

Companies I Founded:
  1. Founder, TexAu, a go-to-market automation platform used by thousands of teams every month, with 200 or more automations, 300 or more templates, and waterfall enrichment.
  2. Founder, RichAPI, a B2B data enrichment API with pay-per-use pricing, multi-provider waterfall logic, and success-weighted billing.
Work Experience:

I have worked with more than 10 clients worldwide as a freelancer and contractor.
  1. Developer, Penta SLL (business bank in Berlin), Remote, October 2017 to March 2018
  2. CTO, Speedbox (logistics startup in Mumbai), February 2017 to September 2017
  3. Automation Team Intern, Slack, San Francisco, June 2016 to August 2016
  4. Software Engineering Intern, Directi, Mumbai, January 2016 to March 2016
  5. Software Engineering Intern, Directi, Mumbai, March 2015 to September 2015
I contribute to open source projects from top companies including Google, Apple, and LinkedIn. I am a core team member of the Node.js Foundation, where I handle the automation project, and a core developer of Botpress, a chatbot building framework. My open source work is available on GitHub.

I also write technical content. I maintain my own blog at Eulercoder and have published with leading tech publications on Medium, including HackerNoon and freeCodeCamp. I was featured as Geek on the Top on GeeksforGeeks, one of the largest computer science portals on the web.

I focus on building APIs, integrations, AI systems, DevOps, and backend development.

I look forward to hearing from you.

Thanks and regards,
Vikesh Tiwari
