---I'm Tahmid, a full stack web engineer with a strong eye for product design and UI/UX. I've also built two open source projects that I want to showcase here. Both projects were a solo effort.
- Forms.md (https://forms.md): Open source TypeForm alternative (350 stars on GitHub), complex project built with JS/TS, fully-tested, lots of functionality. Just launched two weeks ago.
- Halfmoon (https://www.gethalfmoon.com): CSS framework (3k stars on GitHub), drop-in replacement for Bootstrap. 1.1M total downloads (from JSDelivr).
Recently I've worked a lot on RAGs and LLM wrappers, so I have quite a bit of experience with prompt engineering/AI stuff as well.
Application Developer with over a decade of experience.
* Native application development for iOS, Android, Mac and Windows
* Backend services in Go
* Creating and/or integrating APIs/SDKs
* TV/Video applications on all platforms (Apple, Android, Amazon, Roku)
Extensive experience building products and platforms from the ground up.

While I'm familiar with various technologies, my passion lies in programming with Rust. Whether it's backend development, blockchain, compilers, DevOps, embedded systems or mobile applications, I am totally onboard as long as there is a little bit of Rust involved.

I'm a generalist and an opinionated software engineer with experience both in management and as an indepth technical designer, I am looking forward to work with you. If you need a larger team at your disposal, I can arrange that with my industry connections. I guarantee all my work will bring value, or I'm not charging for it. I'm not looking for "cog in the machine coder" type positions :)
Leave me your contact if you'd utilize my help with:
- Large web API implementations
- Automatic code quality checks and processes
- Software Engineer management coaching or mentoring
- Process and scoping help (how to leave development hell)
- Large data streaming and processing systems
... and plenty other things, really. I am certain we can figure out a way to solve your issues in the way that _brings joy_.
I've got 8+ years of senior experience (leading and managing projects and teams). I've recently written code in Go, TS (& React), and Python (deployment and architecture included) with traditional stacks (Postgre, Redis, Kafka, etc. etc) and I'm comfortable with all the modern web tech-stack. I've got some past experience with C#, PHP, and all kinds of scripting languages. I pick up languages quite quickly, so that shouldn't be a problem, and I've got a working knowledge of most programming paradigms.

Hi there! I'm Nitin, a software engineer with a passion for AI/ML, computer vision, and automotive software.
I’ve spent some time at Bosch developing real-time ADAS applications and optimizing perception pipelines, and I'm now deep into research at NC State—exploring information bottlenecks in deep learning and contributing to open-source projects like SGLang. I've also led projects in robotic navigation using Visual SLAM and ROS, fueling my interest in autonomous systems. Lately, I've been diving into AI agents and exploring innovative applications across different domains.
I'm eager to collaborate on challenging projects in robotics, intelligent systems, or any cutting-edge tech. If you're working on something exciting in these areas, let's connect!

Experienced (10+ yrs) full stack product engineer. Very good at both web & mobile & desktop apps, APIs, Postgres, Linux, mentorship, and communication in general. Touch typist, VIM ninja, refactoring monster. With an academic background of philosophy.
Been developing a lot of different projects for different teams, company types (startups, scale-ups, enterprise) and industries (finance, crypto, digital marketing, automation, online education, e-commerce).
My technical specialty is building simple systems with few moving parts that contain as little accidental complexity as possible. I'm pragmatic but always chase proper implementations at the same time. I don’t easily buy the hype nor subscribe to every new shiny tool & paradigm. I focus on robust & reliable software as much as possible.
My business specialty is caring greatly about understanding your domain, business model, figuring out your product priorities and actually iterating fast. In a world where the majority of software projects fail and the majority of engineering hires disappoint, I am promising you the peace of mind of knowing that you have an actually capable engineer beside you who understands your business model, cares about your investment and is able to make good judgements.
Always looking for interesting & challenging projects and smart people.
Feel free to contact if you don't have the luxury of failure.
