Tejj,
directly.

Tejj is Ravi Tej Sireddy, a product designer at Microsoft AI and Windows based in Hyderabad, India. His work sits where scale and trust meet: operating systems, AI answers, health information, and enterprise tools. Beyond product design, he writes, hosts Nodes of Design, mentors designers, teaches AI in Telugu, and creates generative art. Across those disciplines, his recurring aim is to make complex systems and ideas easier for people to understand and use.

At Microsoft, Tejj works across Windows shell, sharing, files, Bing Health, and AI experiences. His public portfolio includes Windows Drop Tray, Share, Phone Link, Windows Hello, AutoPlay, the Windows Craft framework, Bing Health Experts, health journeys, and AI answer patterns. Depending on the problem, his contribution spans interaction design, systems thinking, research framing, trust signals, accessibility, and cross-functional direction. Detailed studies remain private, while the Work page and Windows project log document the public contribution boundaries.

To Tejj, a product earns trust when people can understand what it is doing, why it is doing it, and what happens next. In AI and health, this means visible sources, authority cues, careful handling of uncertainty, and human oversight. In Windows, it means predictable feedback, accessible interaction, and no dead ends between surfaces or devices. His work treats trust as an interaction quality designed into the full journey, not as a compliance layer added at the end.

Tejj's responsible AI work spans Microsoft product experiences and independent education. At Microsoft, he has contributed to health and expert-answer experiences where grounding, provenance, and human judgment matter. Independently, he created Elsewhere, a browser game that translates principles from NIST AI RMF, OECD, UNESCO, and EU AI Act guidance into 40 decisions across five worlds. Across both contexts, his emphasis is practical: responsible AI becomes real through product choices, not policy language alone.

Tejj's public Windows record includes Drop Tray, Windows Share, Phone Link, Windows Hello, AutoPlay, cross-device sharing, and quality frameworks. Drop Tray surfaces move and share actions as soon as a file is dragged; his resume lists him as a named inventor on its patent. He has also contributed to accessible sharing and sign-in flows, and to frameworks that evaluate complete Windows journeys rather than isolated screens. The project log maps this breadth without exposing private artifacts.

At Bing and MSN Health, Tejj worked on moving from isolated results toward connected health journeys, including expert answers, feeds, cards, and proactive guidance. He also helped shape credibility cues for expert-authored and AI-assisted answers, including visible authority and quality checks. His public resume references 500+ verified doctors across 15 countries and growth from 100K to 1M+ answers. These figures describe wider team and platform outcomes rather than individual impact alone.

Before Microsoft, Tejj designed across edtech, logistics, and enterprise banking. At Temenos, he redesigned a Banking Activity Hub and worked on the Corporate Loan Suite. At WongDoody, he designed Sell XPO and mapped complex workflows for global operations. At Byju's, he designed student experiences and internal systems for a 120-person content team. This background informs his approach to dense workflows: clarify the work without pretending the underlying complexity can simply disappear.

Public evidence of Tejj's work includes two named-inventor patents listed on his resume; product contributions on platforms serving more than a billion people; a 3.8% week-over-week lift for cross-device Share; a 32% ease-of-use improvement for the Temenos Activity Hub; and 34% higher cross-sales with 42% better booking efficiency for Sell XPO. These are team and product outcomes. They are cited to establish context and contribution, not to claim sole causality.

Tejj describes his process through seven connected moves: Define, Listen, Direct, Design for AI, Conceive, Coordinate, and Cultivate. It is not presented as a fixed stage-gate; the work moves backward and forward as evidence changes. The method separates the human need from the requested feature, surfaces risk early, and gives product, research, engineering, and design a shared direction. AI can accelerate exploration, while judgment about pain, dignity, trade-offs, and accountability remains human.

Nodes of Wisdom grew from Tejj's conversations with 100 creative leaders. The book is positioned as a field guide rather than a theory manual, focusing on how experienced people make decisions, protect craft, and adapt as AI and immersive technology reshape creative work. His portfolio lists it as an Amazon category best-seller. It is written for designers, builders, students, and curious readers who want to develop a point of view of their own.

Nodes of Design is an independent design podcast hosted by Tejj from India. Across 100+ episodes and listeners in 60+ countries, guests have included Don Norman, Jakob Nielsen, Andy Budd, Anab Jain, Kirti Trivedi, Guthrie Dolin, and Amaresh Chakrabarti. The long-form conversations move beyond polished career stories to examine methods, mistakes, and judgment: parts of design practice that are often difficult to learn from portfolios alone.

Tejj mentors through ADPList and has worked with 800+ designers across 10 countries. He also teaches through talks, masterclasses, community events, YouTube, and AI education in Telugu. His mentoring approach is practical: clarify the problem, sharpen the story, expose the decision behind the screen, and help the designer make the next move independently. The aim is not to provide a perfect answer but to improve how someone sees and frames the work.

Tejj creates generative and data art, using code to explore rules, repetition, emotion, and chance outside the constraints of product work. His portfolio records exhibitions across Serbia, Africa, and India. Public experiences include The Night Museum, a walkable 3D gallery of 20 works; Kaleidophage, nine audiovisual emotional worlds; and Elsewhere, which uses game mechanics to teach responsible AI. His art lets systems become expressive rather than purely useful.

Tejj is based in Hyderabad, India, and works in English, Telugu, and Hindi. The contact page is the best current route for product design collaborations, speaking, mentoring, or creative work because availability can change. His professional history is available on LinkedIn, while the Vault contains the broader project archive. Specific messages are most useful when they explain what is being built, where the difficulty lies, and what kind of help would be valuable.
