About Me

Building at the edge of engineering & delivery

I'm Rakesh Suryavanshi, a forward deployed engineer with an MS in Computer Science from Cal State LA. I've spent 8+ years building production software across the full stack.

Senior software engineer with 8+ years shipping full-stack systems, now focused on moving into Forward Deployed Engineering — where deep technical skills meet direct customer impact. My sweet spot is the gap between a product vision and working software.

My background is in green tech — I've built software for sustainability, energy, and climate-adjacent domains, which means I understand complex regulated industries and the engineering trade-offs that come with them. Currently sharpening my edge on AI/LLM deployments, API integrations, and DevOps.

Multi-tenant — every query scoped by tenant_id, BOLA structurally impossible
Async ingestion: upload → Celery → chunk → embed → pgvector HNSW index
SSE streaming, Redis query/embedding cache, sliding-window rate limiting
Prometheus metrics, structured logging, health endpoints — production-ready

How I Work

The FDE playbook

01 — Discover
Read before the call

I review the codebase before the first meeting. The stated problem is rarely the real one.

02 — Scope
Define what done means

Crisp spec, clear success criteria, explicit boundaries. No surprises mid-engagement.

03 — Ship
Working software fast

Bias toward shipping and iterating. Observability and rollback plans from day one.

04 — Handoff
No black boxes

Docs your team reads. Code your team maintains. Done when the next engineer owns it.

Get In Touch

Let's buildsomething great.

Hard integration, AI product to productionise, or infrastructure that needs to actually work — let's talk. Available within 1–2 weeks.
