Gunjan Vasara
Senior Software Engineer · 7+ YOE · Former Uber Contractor
I'm a senior software engineer who takes features from ambiguity to shipped product — owning UX, engineering, and delivery end to end. Recent work spans enterprise SaaS, data platforms, and AI security tooling.

The Path
Where I've built.
Most of this work was through one employer, across several client engagements — shown here as what each one actually was.
Deuex Solutions Pvt Ltd
Employer · Senior Software Engineer · Remote
12thMen — Sports Team & Tournament Platform
Drove UI/UX architecture and product strategy for a live sports platform featuring real-time auctions and tournament management.
- Led an end-to-end product audit across team creation, auction bidding, and tournament setup to eliminate onboarding friction and improve flow completion.
Highflame — Deuex client · Enterprise LLM Security Platform
Senior software engineer delivering admin-facing UX for an AI coding-agent monitoring platform.
- Built the Code Agents experience from scratch, spanning navigation, agent discovery, usage dashboards, threat analysis, command analysis, and onboarding.
- Drove product and engineering alignment on a platform-wide definition of "threat," establishing consistency across security surfaces.
- Architected a shared telemetry package with a clean UI/API abstraction, enabling telemetry experiences to be reused across enterprise modules.
- Integrated PostHog into the application and configured dashboards to track key user interactions and product usage.
- Investigated inconsistencies in PostHog event tracking, traced the cause to browser ad blockers, and resolved it for affected clients by routing PostHog requests through a Next.js reverse proxy.
- Used PostHog analytics to identify signup friction caused by an insufficiently visible Terms & Conditions checkbox that left the signup button disabled for some users, fixing it to recover completions.
- Led a zero-downtime data-layer migration across Code Agents surfaces as legacy APIs were deprecated, rewriting hooks and validating data correctness throughout the transition.
- Also stabilised the platform's legacy LLM Gateway — consolidating two disconnected Provider/Route UIs into one navigation flow and fixing auth-flow issues (broken admin invites, stale side-panel data) on a product where correctness drives trust.
Uber — Databook — Deuex client · Internal Data Insights Platform
Frontend engineer on an internal developer platform used daily by engineers.
- Led the end-to-end migration of Databook's analytics tracking from Universal Analytics to GA4, remapping UA's category/action/label events to GA4's event/parameter model, replicating view-based segmentation with GA4 data filters, and authoring the team's reference documentation for the new setup.
- Reduced landing-page load time from ~12s to 3s through query optimisation and more efficient data handling.
- Designed and built a recursive tree view for deeply nested input-field hierarchies, balancing state complexity with rendering performance and UI responsiveness.
- Built chat personalisation features — ownership tracking, mentions, bookmarks, filtering, and sorting — from workflow design through GraphQL integration.
- Migrated two legacy table views into more maintainable, structured interfaces.
- Contributed to test coverage using Jest and Playwright, improving confidence in ongoing development.
Coolpanda — Deuex client · Website Revamp
Client-facing lead owning the end-to-end redesign of an outdated, slow-loading website.
- Worked directly with the client to gather requirements, translate them into tickets, and define page navigation and content structure.
- Built a responsive, motion-rich React website with custom Lottie animations designed specifically for the client.
- Guided a small team of designers and a junior developer through delivery, reviewing implementation and keeping the work aligned with the client's vision.
Stealth Startup — Deuex client · System Architecture Visualisation Tool
Sole Frontend Engineer building an interactive, node-and-edge-based system modelling platform.
- Architected and built the core canvas experience, including node CRUD, dynamic graph editing, and rebase workflows with layout history preservation.
- Built sequence/flow execution, allowing users to play back saved flows with step-by-step edge highlighting to visualise process execution.
- Engineered a client-side JSON graph diffing engine with colour-coded change tracking to surface structural and configuration changes.
Also regularly conducted frontend technical interviews at Deuex, evaluating candidates on JavaScript and React fundamentals.
Zeus Learning
Employer · Software Developer · Mumbai · C#, JavaScript
- Built interactive, simulation-based learning platforms replicating Microsoft Office workflows for enterprise clients, progressing from intern to owning multiple modules full-time.
- Tested UI accessibility with screen-reader tools like JAWS, ensuring simulations worked with assistive technology.
