More About Me
Hey there! I'm Deeshan Sharma,
a backend and real-time systems engineer. I build the parts of a product where things have to happen live — chat, calling, media pipelines, event-driven services — and I have been shipping them to production for five years.
I currently lead a backend team, so the work is as much about architecture decisions, code review and clean handover as it is about writing the code myself.

Single-handed Projects
Most of what I build is Node.js and TypeScript — NestJS and Express, MongoDB and Postgres, RabbitMQ when work needs to happen out of band, AWS underneath. When a product needs the rest of itself, I write the Next.js or React front end and the React Native app too; I have shipped mobile apps to both stores.
I ask questions before I write code, and I would rather scope something honestly than underestimate it. If a problem is real-time, event-driven, or works today but might not at ten times the traffic, that is the kind I am best at.

Team Lead & Senior Software Engineer
Jul 25-Present
I lead the backend team — four direct reports, plus mentoring across the wider engineering group — and own architecture and AWS infrastructure across our products. Still hands-on: I prototyped multi-DRM protected video delivery and led the team that integrated it, and I set the review and handover standards the team works to.
Senior Software Engineer
Jul 24 – Jul 25
Full-stack delivery across NestJS services and Next.js clients. This is where most of the shipped product work happened: the AI video-screening platform end to end, the Stripe integration on our real-time conferencing product, and the survey and reporting pipelines behind our market-research platform.
Back End Developer
Jul 21 – Jul 24
The longest stretch, and the one where the foundations were built. I wrote the real-time chat and calling platform that replaced our Slack subscription, built the internal HR portal end to end, and moved our services from Express to NestJS. Senior-scope work through the second half of it, formalised in 2024.
My Projects
Full Stack
Accros: Real Time Chat App
An in-house communication platform — servers, channels, presence, file sharing, and one-to-one audio and video built directly on the browser's WebRTC API with Socket.io signalling and no third-party SDK. Built single-handedly over 18 months and 475 commits to replace a paid Slack subscription.
Backend
HireEQ: AI Hiring Platform
An AI video-screening platform for hiring. Recorded interview answers are pulled from S3, transcoded and frame-sampled with FFmpeg, transcribed with Whisper, scored against a facial-analysis service, and turned into a recruiter report and an Excel export. I built the NestJS backend and the whole asynchronous pipeline.
Backend
DIY: Research Data Platform
A market-research data platform for creative testing: survey authoring, cohort management, a metrics dashboard and spreadsheet export. Four NestJS services on Prisma over a 190-model MySQL schema, alongside two older Express generations and an ETL that keeps a MongoDB analytics store in step with the relational system of record.
Full Stack
HRMS Portal
The internal HR platform for a whole company: leave with real accrual arithmetic, biometric timesheets parsed from the door system, an approvals queue, a shared calendar, templated email and spreadsheet export. Two repos, 312 commits, sole author, still receiving fixes three years on.
Backend
Life OS: AI-Native Personal Ops
A single-user universal inbox running on one machine at home. Anything I send it — a voice note, a photo of a receipt, a forwarded bank email — is transcribed, classified, extracted into typed records and filed. Local models, no cloud. 66 spec files and 561 test cases against 149 source files.
