Capabilities

What I can do as an engineer

Seven areas of professional capability a hiring company can lean on. Each one is grounded in production code I have written, open-source repositories I maintain, and long-form writing I have published. The point of this page is to make the depth legible before any conversation starts.

Seven areas of capability

Each one is a body of work, not a brochure. Follow any tile through to a deeper view, then read the repos and essays that back it.

AI engineering

Production LLM systems built on top of multi-provider failover, retrieval, eval harnesses, voice loops and MCP servers.

Automation engineering

Unattended workflows that route events, parse documents, hit APIs and recover cleanly from partial failure.

Application development

TypeScript and Python services that behave well in production: typed contracts, RLS, audit trails, sensible defaults.

Solution architecture

System design before the first commit. ADRs, trade-off notes, integration diagrams, deliberate stack selection.

Cloud and DevOps

Vercel, Cloudflare, DigitalOcean and Kubernetes wired together with Terraform. Boring, reproducible infrastructure.

Data engineering

Postgres-first pipelines, DuckDB analytics, schema migrations that do not lose data, structured output from documents.

Interface engineering

Tailwind v4 and shadcn/ui interfaces built to production standard. Accessible, responsive, dark-mode native.

Engineering defaults

What is true in every lane

The six defaults below show up regardless of which capability is in play. They are the bar I hold myself to in production code.

Safe defaults, day one

Row-level security on every table, real audit logs, no secrets in the repo. The defaults you would actually want if you cloned the code at midnight.

Observability before features

Structured logs, error tracking and a health endpoint go in before the first feature. You can see the system before you ship the system.

Boring stack, sharp tools

Postgres before Mongo. Server-rendered HTML before another SPA framework. Reach for the exotic only when the boring option genuinely runs out.

Senior IC, end to end

From schema to deploy script, the person on the email is the person at the keyboard. No handoff layers, no junior shuffles.

Write the diagram first

An ADR, a Mermaid sketch, a one-pager of trade-offs. If the system cannot be explained in a paragraph, it is not ready to ship.

Open source by default

Generic infrastructure goes public, MIT-licensed. Eighteen repositories and counting. If a problem is general, the answer should be shared.

Why this matters to a hiring team

Most engineering CVs claim a stack. This page points at the running systems behind each claim. The repositories are public. The essays cite their sources. The architecture diagrams are in the wiki. A hiring team can audit the depth before the first interview, which is the way it should be. Sarma is taking PAYE full-time roles only until 14 February 2030; the hire-me page explains the shape of that.

The evidence behind every lane

Browse the public repositories, read the past-work write-ups, then look at the hiring page.

Nineteen open-source repositories

Everything I rely on in production, published MIT-licensed. Read the code before reading anything else.

Past work, written up plainly

The projects I can talk about publicly, with scope, stack and outcome. The same shape a hiring team would see in a technical review.
