Founding Engineer · Full-stack · Islamabad
A portfolio you can
actually run.
I'm Mujtaba — I help founders turn ideas into software that's reliable enough to bet a business on. This portfolio is built the same way.
system status
Real-time coaching, while the call is still live.
Dextego joins a rep's Zoom / Meet / Teams call, listens, and whispers the next best move in under a second. I'm the founding engineer — I built the platform from an empty repo.
Full-duplex voice, not push-to-talk — server-relayed through OpenAI's Realtime API, with voice-activity detection handling turn-taking so the agent never talks over the rep or the prospect.
how it works
A multi-agent pipeline with memory — built for sub-second turnarounds.
Live audio
Recall.ai bot
Transcription
NestJS gateway
Agent router
Mastra
Reasoning
OpenAI
Live hint
desktop + web
Memory + RAG
Supabase · pgvector
knowledge base
A sync layer over pgvector with two-way OAuth connectors into reps' existing docs and wikis — scoped at the folder/workspace level, so newly added docs sync automatically. The agent pulls this in as searchable context mid-call.
the problem
Reps learn the wrong lesson from lost deals weeks too late. Coaching happens after the call, from memory, if at all. Dextego moves it into the moment — but that only works if the whole loop, from spoken word to on-screen hint, stays under a second and never gets in the way.
my role
- ›Architected the realtime transcript → agent → hint pipeline from scratch.
- ›Built the multi-agent system with persistent memory + RAG knowledge bases.
- ›Shipped billing, credits & enterprise reporting end to end.
- ›Delivered a cross-platform desktop app + Chrome extension in one monorepo.
$ ls ~/agents
Five specialists, one platform.
Every card carries the same six capabilities in the same order — lit when the agent has it, dimmed when it doesn't. Only Tego joins the live call, Esther runs leanest, D-Agent is text-only.
Elite sales roleplay — buyer simulations, objection handling, and live pitch scoring.
Leadership & career coaching — promotion readiness, executive presence, org dynamics.
Mindset & motivation — resilience, rejection recovery, and keeping momentum going.
Product & training expert — answers grounded in your knowledge base.
Onboards new users, answers platform questions, and routes you to the right coach.
what I'd build next
Per-rep hint personalization from won/lost outcomes, and an offline eval harness so we can ship agent changes with confidence instead of vibes.
The AWS-backed backend for a social platform — auth, storage, async events, and automated content safety, owned end to end.
I built and run the infrastructure behind ALLTRUEistic's backend: Cognito for auth, S3 for media storage, SQS + EventBridge for async workflows — plus an automated moderation pipeline (built on AWS's media2cloud) that screens every photo and video for explicit/nude content before it's ever visible to another user.
how it's built
A GraphQL API backed by auth, storage, async events, and automated moderation.
Cognito
auth / user pool

Apollo + subscriptions

content-safety pipeline
SQS + EventBridge
async event bus
Redis + background jobs
cache, scheduled jobs
the problem
A social platform needs more than API endpoints — it needs auth that scales, storage that doesn't leak private media, async processing that doesn't block requests, and a way to catch explicit or abusive content before a human ever sees it. All of that had to be built on AWS from day one.
my role
- ›Integrated Cognito, S3, SQS, and EventBridge as the backend's core infrastructure.
- ›Built the automated content-safety pipeline (S3 → media2cloud) that flags explicit/nude content pre-publish.
- ›Owned the GraphQL schema and data layer as the platform grew.
- ›Designed the background-job system powering recurring events and re-engagement.
Case studies
↑ Dextego (flagship)One week of content, scheduled in seconds.
Sociali turns a brand brief into a full multi-platform posting calendar — generating copy, picking slots, and pushing to Facebook, Instagram & LinkedIn. I built the scheduling engine and the workflow orchestration end to end.
Also built
ALLTRUEistic
The admin panel of a social media platform, facilitating content management and user moderation.
Allo-Dentiste
The admin panel of a dentist appointment app, streamlining appointment scheduling and patient management.
Bookstore
A user-friendly bookstore app that simplifies browsing, purchasing, and managing your favorite books with recommendations and a smooth checkout experience.
Where I've worked

The engineer behind the cursor
Founders bring me the messy version of an idea; I hand back something that runs in production.
Self-taught, three years deep, ten-plus products live across AI, tele-health and SaaS. I optimize for the boring wins — less risk, faster delivery, systems that don't rot.
And because I'm a bibliophile, I care as much about how it reads as how it runs.
Let's build something worth shipping.
