About me

Tharshan Balasingham, drawn as a dot raster

Hey, I am Tharshan.

A software developer by training, a Product Owner by day — and under LiTha Solutions both at once: I clarify what should be built, then build it.

What I work with

  • AI

    Claude API, AWS Bedrock, tool-use loops, vector search, multi-stage model chains

    News sentiment, quarterly reports and fundamentals through a chain of language models, all hosted in the EU — every figure carries its source.

  • Backend

    Python with FastAPI, TypeScript with Fastify and Hono, Postgres, MongoDB, SQLite

    A collector that machines without an open port report to themselves, instead of being polled.

    View project: LiTha Monitor

  • Frontend

    Next.js, React, Astro, Tailwind, PWAs

    A dictated paragraph becomes individual tasks with dates and urgency; installable as an app, keeps working offline.

  • Mobile

    Expo, React Native, Tamagui, local-first with custom sync

    One codebase for web, iOS and Android; the running timer sits on the lock screen without opening the app.

  • Operations

    Docker, nginx, systemd, own VPS, Datadog, Sentry, Plausible

    Served statically through nginx with a small hardened service for the form — when the restaurant became a massage studio, the site followed within two days.

How I work

Spec-driven, which sounds unremarkable and makes the difference day to day: clarify what should be built, then the architecture, then small self-contained steps with automated checks in between. The reason is experience rather than tidiness — software only I can operate is not good software.

I run my own servers. Two machines: one for everything live, one for builds and background work. That split came after an outage where compute-heavy processes slowed the production machine down. You learn those things once.

Milestones

  1. 2022

    Vocational training as a software developer; in December the first lines of Flexer, a fitness app that still runs today.

    First client projects: a Berlin Thai restaurant, then a Thai massage studio.

  3. 2025

    After training, Technical Product Owner in the automotive industry. LiTha Solutions founded in May; consulting and concept work for a renowned Berlin university, conversations with medical practices and medical supply stores.

  4. 2026

    Technical AI Product Owner at a logistics software company — applying AI, not researching it. Moved to Hamburg. Since August LiTha Solutions as a sole proprietorship; Trade Insight in the AWS and Datadog startup programmes.

Why solo

Because I can, and because for the project sizes involved here it is more honest. You talk to the person who also builds. No intermediate layer, no handover to someone you never meet. The price is limited capacity — which is why I also say no when a project does not fit.
