    SEEKING WORK | Chennai, India | Remote 

    Technologies: Java, Golang, Angular, SpringBoot, Python, Django, Flask, SQL/NOSQL, OpenAPI, LLMs 
    Projects: https://home.alles-tools.com/
    Email: suvarnanarayanan2g (at) gmail.com
    

I'm a backend developer for the most part but I also do full stack development if the UI isn't highly complex. Before I got laid off - I was making it @ Autodesk.

I have quite some experience dealing with LLM based applications - taming them into giving more sane answers. The best one that I have built so far lets you attach to any data sources (SQL/NoSQL/Files) etc and then just ask questions about them. Literally any question (even outside the schema) and it never makes up stuff.

My going rate at the moment is $5 per hour (subject to complexity and my preference) - capped at 8 hours a day for 5 days a week, which is around $200/wk at minimum.

I am very transparent about my work and I do not ask for payment beforehand and no compulsion to pay if work is not up to your standards. Also, before I take you as my client, we will do a call - this helps me to have a measure at your expectations/requirements and helps to build a bond which is something I really value.

If you prefer - you could directly schedule a meet @ https://calendly.com/suvarnanarayanan2g/30min?month=2025-07

If you cannot make the slots to work for the calendar above, please shoot me an email and I will do a meet at a time you are comfortable with. Cheers!

  Email:[email protected]

I've had the opportunity to work as a founding engineer at multiple companies, where I've been involved in building and scaling platforms from scratch. At PreFix Inc., I led the backend development of our home maintenance platform, working as the sole backend engineer early on. I played a key role in scaling the customer base, integrating critical systems like Zendesk, Stripe, and HubSpot, and developing our business intelligence platform to enable data-driven decision-making. I also helped expand the engineering team and contributed to major partnerships, including a successful pilot program with a large insurance company, and the many security, privacy and data handling challenges that entails.

Before that, at Ruckit, I was part of the founding team where we developed a collaborative logistics platform that scaled the company to over $2M in monthly revenue. I managed a distributed team of engineers, drove third-party integrations, and helped position the company for acquisition by Command Alkon.

Now it's time for something new. You can checkout my CV/resume linked above for lots more details, and please reach out with any interesting opportunities.

I’m a machine learning researcher and former software engineer, currently working independently on a deep dive into probabilistic models, inference, and machine learning theory — including a comprehensive solutions manual for Bishop’s Pattern Recognition and Machine Learning.

You can have a look at my progress here : https://github.com/abhimanyu-jain/PRML_Solutions

I’m looking for work where I can apply this theoretical depth — ideally roles involving ML research, prototyping, or model optimization — or contribute to academic or open-source projects with strong mathematical foundations.

I have a Master’s from Boston University focused on ML, and ~5 years industry experience (Python, backend). I’m especially interested in:

Algorithmic research and model development

Teams that blend theory and implementation

Teams working on open-ended problems

I’m flexible, fast-learning, and love pushing through complexity.

Major Incident: Take Command before your IT hits the fan.

Hi, I’m Vincent — a one-man consultancy for service managers who need a second brain, a sounding board, or someone who’s seen worse.

With over a decade of hands-on experience in IT and Logistics operations, service quality, and process improvement, I help teams under pressure make sense of what’s actually happening, and what to do next.

Common reasons clients call me in: – Support is overwhelmed and nothing’s improving – Tooling, processes and roles are unclear, but nobody has time to fix it – Team leads or Service Managers are stuck and need a sparring partner – Leadership wants answers, and all you have is noise

This is call-a-friend consulting. Tactical. Direct. Remote-first.
