Runtime bugs that surface after launch are expensive to trace and fix — type safety catches most of them in your editor, months before a user ever hits that code path. That's the difference between an API route where a typo in a field name throws in production at 2am versus one where TypeScript flags it before you commit. From React components with strongly typed props to Node.js APIs with typed request and response contracts, I build type-safe applications across the entire stack — not just the parts that are easy to type.

Why TypeScript
Why TypeScript?
TypeScript isn't just about catching errors — it's about building applications that are easier to maintain, refactor, and scale. If your product is a subscription business, see SaaS MVP development, or hire a full-stack developer if you need the backend built too.
Fewer Runtime Errors
A mistyped API field or a null you forgot to handle gets caught during development instead of surfacing as a production error weeks after launch.
Better Maintainability
An interface documents what a function actually expects and returns, so a new developer — or me, six months later — doesn't have to reverse-engineer it from usage.
Better Developer Experience
Autocomplete, jump-to-definition, and safe rename-across-files refactoring work reliably across the entire codebase, not just within a single file.
Scalable Architecture
Generics and strict interfaces keep large frontend and backend applications coherent as they grow, instead of accumulating any-typed escape hatches that quietly reintroduce the bugs types were supposed to prevent.

What I build
What can I build with TypeScript?
From SaaS platforms to real-time applications — every product is built with type safety in mind.
SaaS Applications
Type-safe SaaS platforms where the subscription tier, billing state, and tenant permissions are modelled as types — so an unhandled plan or role isn't a runtime surprise.
APIs
Strongly typed REST APIs with request and response contracts shared between frontend and backend, so a backend change that breaks the frontend fails at compile time, not in a user's browser.
Dashboards
Analytics dashboards and admin panels where chart and table components are typed against the actual data shape, catching a mismatched field before it renders as blank or wrong.
AI Applications
AI-powered applications where streamed LLM responses and API integrations are typed end to end, so a malformed response gets caught instead of silently breaking the UI.
Admin Platforms
Role-based admin systems with typed permissions and data models, so a missing permission check shows up as a type error during development instead of an access bug in production.
Real-time Applications
Real-time features with typed WebSocket event payloads, so the client and server agree on the shape of every message instead of guessing at runtime.
E-commerce
Type-safe e-commerce platforms where cart, order, and payment state are modelled as types, reducing the class of bugs where a checkout silently fails on an unexpected field.
Internal Tools
Custom business tools with typed workflows and validated data models, so a form submission that doesn't match the expected shape gets rejected before it reaches your database.
Selected work
Complete digital products, not just websites
SaaS platforms, AI systems, mobile apps, automation pipelines and business management platforms — designed, built and shipped for real clients.
Swasthify — Healthcare Management Platform
A healthcare platform with four different user roles and multiple payment and record-upload flows — the kind of surface area where a single mistyped API field could silently corrupt a patient record instead of failing loudly, which made getting the types right across the Node.js backend and Next.js frontend non-negotiable.
Web platform + Android application supporting 10k+ users across projects.
AI
AI Voice Interview Platform — Real-time Voice Assessment
A real-time voice interview platform where conversational AI, voice interaction, and evaluation logic all pass structured data between services — typed contracts between the Gemini/Vapi integration and the evaluation pipeline prevent an entire class of bugs that would otherwise only show up mid-interview.
AI
AI Video Ads Generator — Automated Content Creation
An AI-powered platform that helps generate promotional video advertisements through an automated content creation workflow.
Automation
Flying Alpha — Automation Platform
A SaaS automation platform where workflow definitions and their execution state have to stay in sync — typed workflow schemas catch a broken automation step during development instead of after it's already skipped a step for a customer.
Donation / NGO
Bring Smile — Donation Platform
A modern donation website designed to help organizations collect donations, communicate their mission and create a simple digital fundraising experience.
Donation / NGO
Plan to Empower — Donation Platform
A purpose-driven donation platform focused on connecting supporters with meaningful social initiatives through a clean and accessible digital experience.
Finance
Legal257 — Finance & Loan CMS
A finance and loan management platform designed to simplify financial service operations, content management and customer workflows.
Donation / NGO
Jonojivan — Donation Platform
A donation-focused digital platform built to support social initiatives, manage campaigns and provide an accessible contribution experience.
E-commerce
Jonojivan — E-commerce Platform
An e-commerce platform designed to manage products, customers, orders and online commerce workflows.
AI Blog Automation Platform
Multi-worker AI automation system
A multi-worker content pipeline — research, planning, outline, and writing workers passing data through BullMQ queues — where typed job payloads keep every worker speaking the same schema instead of one worker's output silently breaking the next stage.
Factory Management Platform
Manufacturing ERP
A complete manufacturing management platform for managing factory operations, workforce, raw materials, agents, distributors, offers, inventory and sales from one centralized system.

When to hire
When should you hire a TypeScript developer?
TypeScript is especially useful when you're building a product that will continue growing.
SaaS Products
A SaaS product's data model — plans, permissions, billing state — only gets more complex over time, and types keep that complexity from turning into scattered runtime checks.
Large React Applications
As a React app grows past a handful of components, typed props stop prop-drilling bugs and undocumented component contracts before they compound.
Startup Products
Startups pivot scope constantly — TypeScript lets you refactor confidently because the compiler tells you everywhere a change breaks, instead of finding out from a user.
API-Heavy Applications
When frontend and backend are built by the same typed contracts, integration bugs from mismatched fields or renamed endpoints get caught before deployment, not after.
Team Development
Shared interfaces act as a contract between developers working on different parts of the same codebase, without needing a meeting to agree on a data shape.
Long-term Projects
Applications expected to stay in production for years accumulate the most value from TypeScript, since every future change is checked against the types already in place.
