I am Aashish
Software Engineer | Fullstack & AI Systems
Building scalable backend systems, AI retrieval workflows, and real-time applications using Node.js, FastAPI, React, and AWS.
Focused on retrieval systems, async processing, event-driven architectures, and production AI workflows.
Focus Areas
Scalable backend systems, APIs, and distributed workflows
Retrieval systems, RAG pipelines, and AI-powered applications
Real-time systems, async processing, queues, and event-driven architectures
I turn messy ideas into working products.
I help startups and businesses build scalable digital products, from high-performance backend systems to AI-powered applications and fullstack modern web platforms.
My experience spans full-stack product development, custom AI integrations, event-driven architectures, and real-time systems, with a focus on writing clean, maintainable software that scales with the business.
I enjoy collaborating closely with teams, solving difficult technical problems, and shipping reliable products that create real impact.
Beyond code
When I’m away from the keyboard, you’ll usually find me on a motorbike, riding through the ghats of Maharashtra or along the Konkan coast with my Wife🫰🏻 or the Boys.
Systems First
I approach problems by understanding the bigger picture before diving into code.
Fast Execution
I ship fast without sacrificing quality. If it can be automated, I automate it.
Clean Code
Readable, maintainable code that other engineers actually enjoy working with.
Where I've built things that matter
From startups to scale-ups, I've built systems designed for scale, reliability, and real-world usage.
Software Developer Engineer
- Owned end-to-end development of a multi-tenant Help Center platform with a real-time editor and live preview.
- Contributed to a production AI platform serving 100k+ users, building event-driven LLM pipelines.
- Integrated Slack/Teams webhooks to power AI-powered workflows.
- Refined prompt design and retrieval strategies to increase relevance and reduce hallucinations in enterprise use cases.
Full-Stack Engineer (Contract)
- Designed an event-driven HLS video pipeline using S3 triggers and Lambda transcoders for adaptive bitrate streaming.
- Reduced API P95 latency from 6s to 3s by resolving N+1 query patterns and optimizing MongoDB indexing and population.
- Improved throughput via parallelization with Promise.all() and tuning MongoDB connection pooling.
- Led cross-functional teams to ship performance-critical features using Node.js, Docker, and AWS.
Backend Engineer
- Built and maintained RESTful APIs for creator-business collaboration workflows including transaction management.
- Integrated Stripe and PayPal payment gateways, handling complex webhook events for diverse transaction states.
- Optimized Firebase read performance by implementing batch queries, reducing redundant high-frequency data access.
- Migrated backend codebase from JavaScript to TypeScript, enforcing strict typing across all API contracts.
Things I've shipped to prod
A full-stack SaaS for real-time resume analysis and JD matching. Features structured parsing and semantic matching using Gemini API and cosine similarity.
A production-grade non-profit platform built with Next.js. Leveraged custom JSON-LD schemas and advanced SEO architecture to secure international visibility, driving the NGO's first organic donation within 7 days of launch.
An event-driven, serverless media pipeline for adaptive bitrate video streaming. Built based on the production system deployed at SEEme Inc to automate high-throughput transcoding.
Technical Deep Dives
Technical investigations, practical guides, and lessons learned while building software.
How I Found a Fake Job Assessment Repo Hiding Malware Inside SVG Files
While auditing a take-home interview assignment, I uncovered malware hidden inside static SVG files. This write-up walks through how the exploit was structured, what it targets, and how to safely audit third-party code before running it locally.
Building Telegram Bots with Telegraf.js
A practical guide to building Telegram bots with Telegraf.js, covering architecture, environment configuration in Node.js.
