Building high-scale systems & AI applications.
I'm Manas Upadhyay, a Software Engineer with nearly 4 years of experience building scalable AI web applications, and a gym freak. Based in India.
Things I've built
FeesBook
A subscription based Android app that replaces the paper fee register for coaching institutes student records, fee collection tracking, dues and receipts in one place. Built solo with Flutter and a Django backend, shipped to the Play Store, and grown to 6K+ downloads with ₹3L+ in subscription revenue in its first 6 months.

SyneHQ
A client engagement, not a side project SyneHQ lets teams explore and act on data across all their sources by asking questions in natural language. As the sole engineer, I took the platform from zero to launch in 4 months: the AI query layer, SQL/Python notebooks, multi-source integrations, and the product around them.

What clients say
“Manas was the sole engineer on SyneHQ and took the platform from zero to launch in four months. He owned everything architecture, the AI layer, infrastructure and delivered like a whole team.”
Where I've shipped
Architecting production-grade Generative AI systems — multi-agent orchestration, image generation pipelines, and scalable backend infrastructure powering global fashion brands.
- Architected a dynamic multi-agent orchestration system in JavaScript — a runtime orchestrator that routes tasks across role-specialized agents (research, generate, validate) via a custom skills framework, powering multiple AI workflows across production systems.
- Designed a skills-based agent framework enabling modular capability assignment per agent, decoupling orchestration from execution — improving extensibility and enabling rapid deployment of new AI workflows without re-engineering core pipelines.
- Migrated the core image generation pipeline to a next-gen architecture, significantly reducing production failure rates and elevating performance across 500K+ monthly generations.
- Engineered an end-to-end AI-powered marketing outbound pipeline — ingesting CSV user lists, auto-scraping brand sites for product extraction, computing semantic brand-aesthetic embeddings for template matching, and triggering personalized image generation for hyper-personalized email campaigns at scale.
- Built brand & template personalization using cosine similarity, matching fashion brands to hyper-personalized templates aligned with their brand guidelines.
- Built a custom training pipeline with AI Toolkit and Flux Context Portrait models, producing 500+ fine-tuned fashion models for editorial generation at scale.
- Engineered Bulk Click Generation from scratch — the company’s second customer-facing feature launch — enabling scalable bulk editorial image generation and producing 500K+ images in production.
- Designed and maintained multiple AI image transformation pipelines (image-to-ghost, image-to-sketch, image-padding) powering editorial tooling that generates 250K images monthly across global fashion brands.
- Implemented interactive in-product guided tours and continuous UI/UX enhancements, improving platform stability, user activation, and retention.
Sole engineer for SyneHQ — an AI-native data analytics platform where teams query their data in natural language. Built the product end to end as a freelance engagement, from architecture to launch.
- Designed and built the entire platform single-handedly — frontend, backend, AI query layer and deployments — taking the product from zero to a launched, customer-facing platform in 4 months.
- Built the AI-assisted analytics core: natural-language querying over connected data sources with SQL/Python notebook workflows for analysts.
- Implemented multi-source data integrations and the connection layer powering centralized analysis across customer warehouses and databases.
- Worked directly with the founder, owning scope, technical decisions and delivery end to end — the engagement every freelancer wants to be trusted with.
Full-stack product and high-fidelity frontend work — story-driven landing experiences and scalable backend systems.
- Developed 15+ interactive landing pages in Next.js with advanced scroll animations using GSAP & Framer Motion — crafting smooth, story-driven experiences aligned with brand identity that increased engagement.
- Architected a scalable notification system for custom notifications over text / WhatsApp / email.
- Collaborated with 4+ developers to build an e-commerce platform capable of supporting 1M+ monthly visitors.
Full-stack development across mobile and web for internal tools and client applications.
- Developed a mobile application from scratch using React Native + TypeScript, resulting in a 20% increase in hiring efficiency in the third quarter.
- Designed and implemented the front end of the terminal application using React.js + TypeScript, boosting admin efficiency by 30%.
- Migrated the backend of the employee portal from PHP to Node.js.
- Developed APIs for the dispatch application using Node.js as the backend framework.
